Mahalanobis distance-based traffic matrix estimation Dingde Jiang, Xingwei Wang, Lei Guo http://onlinelibrary.wiley.com/doi/10.1002/ett.1382/pdf This letter studies large-scale IP traffic matrix (TM) estimation problem and proposes a novel method called the Mahalanobis distance-based regressive inference (MDRI). By using Mahalanobis distance as an optimal metric, we can get rid of the highly ill-posed nature of this problem. We describe the TM estimation into an optimal process, and then by optimising the regularised equation about this problem, TM’s estimation can accurately obtained. Testing results are shown to be promising.

Cross-layer optimisation for uplink transmission in OFDMA cellular networks with fixed relays Lei You, Ping Wu, Mei Song, Junde Song, Yong Zhang http://onlinelibrary.wiley.com/doi/10.1002/ett.1480/pdf In this paper, we consider a cross-layer design aimed to enhance performance for uplink transmission in an orthogonal frequency division multiple-access (OFDMA)-based cellular network with fixed relay stations. Because mobile stations (MSs) spend most of the power on the uplink transmission, power efficiency resource allocation becomes very important to MSs. We develop a cross-layer optimisation framework for two types of uplink flows (inelastic and elastic flows) that have different quality-ofservice requirements. For inelastic flows with fixed-rate requirement, we formulate the cross-layer optimisation problem as the minimisation of the sum transmission power of MSs under the constraints of flow conservation law, subcarrier assignment, relaying path selection and power allocation. For elastic flows with flexible-servicerate requirement, we consider the cross-layer trade-off between uplink service rate and power consumption of MSs and pose the optimisation problem as the maximisation of a linear combination of utility (of service rates) and power consumption (of MSs). Different trade-offs can be achieved by varying the weighting parameters. Dual decomposition and subgradient methods are used to solve the problems optimally with reduced computational complexity.The simulation results show that, through the proposed cross-layer resource optimisation framework and algorithms, significant benefits of deployment of multiple fixed relays in an OFDMA cellular network can be fully obtained such as reduction in power consumption, increase in service rate and energy savings in the uplink transmission of MSs.

On fair rate adaption in interference-limited systems Anke Schmeink http://onlinelibrary.wiley.com/doi/10.1002/ett.1469/pdf A fair allocation of scarce resources is crucial in systems where multiple entities compete for the same goods. General interference-limited communication systems with rate adaption are investigated in this paper and the problem of fair resource allocation is addressed by two different approaches. First, a non game theoretic fairness approach is applied to the system model. Then bargaining theory is exploited to derive a game theoretic fairness concept. To compensate the information transmission necessary in the bargaining game, so-called incentive parameters are introduced. The solution of the thereby obtained local problem coincides with the Nash bargaining solution of the global problem if the incentive parameters are properly chosen. Numerical results show the advantage of the game theoretical modelling with respect to fairness and efficiency.

Performance analysis of system with L-branch selection combining over correlated Weibull fading channels in the presence of cochannel interference

Mihajlo Cˇ. Stefanovic’, Dragan Lj. Drac’a, Aleksandra S. Panajotovic’, Nikola M. Sekulovic’ http://onlinelibrary.wiley.com/doi/10.1002/dac.1050/pdf In this paper, the performance of L-branch selection combining receiver over correlated Weibull fading channels in the presence of correlated Weibull-distributed cochannel interference is analyzed. Closed-form expressions for probability density function and cumulative distribution function of the signal-to-interference ratio at the output of the selection combining receiver present main contribution of this paper. Numerical results are also presented to show the effects of various parameters as the fading severity, correlation and number of branches on outage probability.

Cryptanalysis of a simple three-party password-based key exchange protocol Eun-Jun Yoon, Kee-Young Yoo http://onlinelibrary.wiley.com/doi/10.1002/dac.1168/pdf In order to secure communications between two clients with a trusted server’s help in public network environments, a three-party authenticated key exchange (3PAKE) protocol is used to provide the transaction confidentiality and the efficiency. In 2009, Huang proposed a simple three-party password-based authenticated key exchange (HS-3PAKE) protocol without any server’s public key. By analysis, Huang claimed that the proposed HS-3PAKE protocol is not only secure against various attacks, but also more efficient than previously proposed 3PAKE protocols. However, this paper demonstrates that HS-3PAKE protocol is vulnerable to undetectable online password guessing attacks and off-line password guessing attacks by any other user.

A QoE management system to improve the IPTV network Jaime Lloret, Miguel Garcia, Marcelo Atenas, Alejandro Canovas http://onlinelibrary.wiley.com/doi/10.1002/dac.1145/pdf One of the biggest problems of the IPTV providers is to offer enough quality of experience (QoE) to their customers. The minimum bandwidth in the access network required to provide IPTV services, jointly with the necessity to guarantee the QoE to the customers, creates the need for new type of algorithms to satisfy the network requirements. Apart from the parameters that depend on the application aspect and design, the user’s QoE mainly depends on the video quality (VQ), which can be affected by the network parameters (jitter, delay, lost packets, etc.), and on other parameters, such as zapping time and synchronization time. In this paper, we implement several benches to know how each measurable parameter affects the user’s QoE. Taking into account these parameters, we propose an analytical expression for the QoE calculation. Then, the paper presents a network management algorithm that takes into account the information received by the user to take the appropriate actions and vary some features of the IP network to provide enough IPTV QoE to the customer. Finally, we measure how one of the actions taken by our system affects the network performance and the VQ.

Dependability evaluation of integrated circuits at design time against laser fault injection Huiyun Li, Hai Yuan http://onlinelibrary.wiley.com/doi/10.1002/sec.327/pdf Laser fault injection has been proved to be a useful tool for attacks on integrated circuits. Transistors hit by a pulse of photons causes them to conduct transiently, thereby introducing transient logic errors, such as register value modifications, memory dumping, and so on. Attackers can make use of this abnormal behavior and extract sensitive information that the devices try to protect. This paper demonstrates laser fault injection attacks on very-large-scale integration circuits in a semi-invasive way for the purpose of validating fault tolerant design and performance. Then, the paper presents a simulation methodology to evaluate the dependability of the integrated circuit design against laser fault injection attacks at design time. This simulation methodology involves exhaustively scanning the layout, incorporating the exposed cells into a circuit simulator, and examining the response of the circuit in detail. Experiments conducted on the same test chip spot the same vulnerabilities, thus indicating the validity of the proposed simulation methodology.

Protocol for ownership transfer across authorities: with the ability to assign transfer target Ming Hour Yang, Hung Yuan Hu http://onlinelibrary.wiley.com/doi/10.1002/sec.300/pdf Radio Frequency Identification (RFID) has been widely deployed for its high capabilities in simple computation, storage, long scan distance, and simultaneous reading. With the combination of mobile devices and readers in recent years, it has been transformed to mobile RFID providing wider services for its users and mobility for its readers. E-commerce, for instance, has applied many of mobile RFID’s deriving services, one of which is the transfer of a tagged item’s ownership. To secure such transfer in a mobile RFID environment, we propose a new approach for ownership transfer across different authorities and prove it able to stand most threats for RFID and to prevent Denial of Service (DoS) attacks that derive from asynchrony. Another contribution in this paper is that we can assign transfer targets, which, except our scheme, can only be achieved by Yang et al.’s Cross Authority Ownership Transfer (CAOT) protocol. That scheme, however, involves heavy computation and is not suitable for lightweight tags, whereas this scheme is designed for lightweight tags and has been proved viable on low-cost passive tags and has better performance than any known ownership transfer schemes.

Simulation study of IEEE 802.15.4 LR-WPAN for industrial applications Feng Chen, Nan Wang, Reinhard German, Falko Dressler http://onlinelibrary.wiley.com/doi/10.1002/wcm.736/pdf The IEEE 802.15.4 protocol has become the primary solution for many low-rate wireless personal area network (LR-WPAN) applications. This is especially the case for industrial sensor network applications such as automation control. We contribute to the better understanding of the protocol behavior by presenting a set of results of simulation experiments. Our results outline the capabilities of this protocol in the selected scenarios but also the limitations. In particular, we investigated the dependency of the protocol on protocol-inherent parameters such as the beacon order and the superframe order but also to different traffic load. Our results can be used for planning and deploying IEEE 802.15.4- based sensor networks with specific performance demands. We put a special focus on application scenarios in industrial sensor network applications. The primary requirements are reduced end-to-end latency and energy consumption. Our studies are based on our new implementation of IEEE 802.15.4 developed for the simulation framework OMNeT++.

Secure handover for Proxy Mobile IPv6 in next-generation communications: scenarios and performance Jong-Hyouk Lee, Tai-Myoung Chung http://onlinelibrary.wiley.com/doi/10.1002/wcm.895/pdf As wireless mobile network technologies have grown tremendously over the past few years, security issues of protecting user privacy and network resources have emerged. Particularly, a mobile node (MN) must be authenticated in order to utilize the network resources whenever the MN performs its initial access or handover. In this paper, we present secure handover scenarios for Proxy Mobile IPv6 (PMIPv6): namely, handover re-authentication (HORA)and handover early-authentication (HOEA). The presented secure handover scenarios are based on EAP that is a common authentication framework for wireless mobile networks. Analysis results for the total handover latency and packet loss are presented to demonstrate whether the presented secure handover scenarios satisfy with real-time applications. PMIPv6 is in the early stage of deployment in various wireless mobile networks. The conducted results in this paper thus offer the key to an understanding of feasibility of PMIPv6 in the coming next-generation network environments.

Performance and diversity analysis of decode-and-forward cooperative system over Nakagami-m fading channels Yongxu Hu, Kwok Hung Li, Kah Chan Teh http://onlinelibrary.wiley.com/doi/10.1002/wcm.866/pdf In this paper, we derive the upper bound of bit-error rate (BER) performance and diversity gain for a decode-and-forward (DF) cooperative system. Either maximal-ratio combining (MRC) or cooperative MRC (C-MRC) is employed at the receiver in the presence of independent, non-identical Nakagami-m fading. Both analytical and simulation results show that C-MRC takes advantage of spatial diversity more efficiently and thus achieves the same or better performance and diversity order as compared to MRC.

Modern computer networks and communication systems are increasing in size, scope, and heterogeneity. The promise of a single end-to-end technology has not been realized and likely never will occur. The decreasing cost of bandwidth is increasing the possible applications of computer networks and communication systems to entirely new domains. Problems in integrating heterogeneous wired and wireless technologies, ensuring security and quality of service, and reliably operating large-scale systems including cloud computing have all emerged as important topics. The one constant is the need for network management. Challenges in network management have never been greater than they are today. The International Journal of Network Management is the forum for researchers, developers, and practitioners in network management to present their work to an international audience. The journal is dedicated to the dissemination of information, which will enable improved management, operation, and maintenance of computer networks and communication systems. Topic areas for the journal are largely defined by the taxonomy for network and service management developed by IFIP WG6.6, together with IEEE-CNOM, the IRTF-NMRG and the Emanics Network of Excellence.

A novel weighted clustering algorithm in mobile ad hoc networks using discrete particle swarm optimization (DPSOWCA) Bin Yang, Jinwu Xu, Jianhong Yang, Debin Yang http://onlinelibrary.wiley.com/doi/10.1002/nem.730/pdf In this paper, a novel weighted clustering algorithm in mobile ad hoc networks using discrete particle swarm optimization (DPSOWCA) is proposed. The proposed algorithm shows how discrete particle swarm optimization can be useful in enhancing the performance of clustering algorithms in mobile ad hoc networks. Consequently, it results in the minimum number of clusters and hence minimum cluster heads. The goals of the algorithm are to minimize the number of cluster heads, to enhance network stability, to maximize network lifetime, and to achieve good end-to-end performance. Analysis and simulation of the algorithm have been implemented and the validity of the algorithm has been proved. Results show that the proposed algorithm performs better than the existing weight-based clustering algorithm and adapts to different kinds of network conditions.

Mitigating unfairness in locality-aware peer-to-peer networks Frank Lehrieder, Simon Oechsner, Tobias Hoßfeld, Dirk Staehle, Zoran Despotovic, Wolfgang Kellerer, Maximilian Michel http://onlinelibrary.wiley.com/doi/10.1002/nem.772/pdf Locality awareness is considered as a promising approach to increase the efficiency of content distribution by peer-to-peer (P2P) networks, e.g., BitTorrent. It is intended to reduce the interdomain traffic, which is costly for Internet service providers (ISPs), and to simultaneously increase the performance from the viewpoint of P2P users, i.e., to shorten download times. This win–win situation should be achieved by a preferred exchange of information between peers which are located close to each other in the underlying network topology. A set of studies shows that these approaches can lead to a win–win situation under certain conditions, and to a win–no lose situation in most cases. However, the scenarios used mostly assume homogeneous peer distributions. This is not the case in practice according to recent measurement studies. Therefore, we extend previous work in this paper by studying scenarios with real-life, skewed peer distributions. We show that even a win–no lose situation is difficult to achieve under those conditions and that the actual impact for a specific peer heavily depends on the used localityaware peer selection and the specific scenario. This contradicts the principle of economic traffic management (ETM), which aims for a solution where all involved players benefit and consequently have an incentive to adopt locality awareness.

Traffic engineering supported by Inherent Network Management: analysis of resource efficiency and cost saving potential Gerhard Haßlinger, Giorgio Nunzi, Catalin Meirosu, Changpeng Fan, Frank-Uwe Andersen http://onlinelibrary.wiley.com/doi/10.1002/nem.770/pdf Future Internet, inherent traffic and network management as well as the corresponding business aspects are topics of intensive research activity. The combination of those areas is a main focus of Inherent Network Management (INM) as a management framework based on distributed, selforganizing and autonomous approaches to address new challenges in a trend towards heterogeneous and dynamic future networking environments. We describe the INM design and behaviors especially with regard to advanced monitoring and fast failure response to enable more flexibility in traffic engineering, in order to improve the control and utilization of bandwidth and other network resources. We analyze a case study on the process of upgrading the links in broadband access networks, as a steadily ongoing planning procedure in operational fixed and mobile networks to keep pace with rapidly growing user demand and Internet traffic.

Teschl, J. Kyrolainen, P. Valtr http://onlinelibrary.wiley.com/doi/10.1002/sat.955/pdf This paper presents a hybrid empirical-statistical model for the satellite-to-indoor propagation channel at S-band derived from measurements using a helicopter to simulate the satellite.The measurements have been carried out by means of a wideband, circularly polarized channel sounder in a SIMO (Single Input Multiple Output) configuration, allowing the derivation of entry loss, wideband and spatial model parameters. It is hoped that this paper will provide relevant information on the satellite-to-indoor channel given the large amount of experimental data available, covering a significant member of different buildings of various types, and the amount of measurement configurations: elevations and azimuths.

WISECOM: A rapidly deployable satellite backhauling system for emergency situations Matteo Berioli, Javier Mulero Chaves, Nicolas Courville, Philippe Boutry, Jean-Louis Fondere, Harald Skinnemoen, Hillar Tork, Markus Werner, Michael Weinlich http://onlinelibrary.wiley.com/doi/10.1002/sat.982/pdf This paper presents the detailed architecture of the WISECOM system, which can quickly re-establish and provide telecommunication services after a disaster by integrating terrestrial mobile radio networks, such as GSM, WiFi, WiMAX and TETRA, with satellite technologies. The system aims to be a useful tool to be deployed in the early hours after a disaster event, for both the victims and the rescue services who will be able to communicate in a reliable and robust way, improving the coordination of the different teams and reducing the time needed to provide victims with the proper treatment. The paper presents in detail the different services provided by the system taking into account its two different versions, based on two different satellite technologies, Inmarsat BGAN and DVBRCS. Together with the presentation of the system capabilities, a business model is also proposed. Thereafter, the architecture of the general system and the demonstrators that have been developed are detailed, according to the two versions of the system. The work also presents the outcomes of the tests conducted with a prototype of the system, and of the final project demonstration, which was held in Germany in May 2008 with the involvement of real end-users (fire brigades and civil protection authorities).

A cooperative transmit diversity scheme for mobile satellite broadcasting systems Do Seob Ahn, Sooyoung Kim, Hee Wook Kim, Dong-Chul Park http://onlinelibrary.wiley.com/doi/10.1002/sat.967/pdf In this study, we propose an efficient cooperative diversity scheme for mobile satellite multimedia broadcasting systems.The proposed scheme is a transmit diversity technique for adapting different channel environments, and thus, no channel quality information from the return link is needed. In the proposed scheme, we utilize space – time block codes and rate-compatible turbo codes to achieve diversity gains and additional coding gains, respectively. The satellite and several repeaters on the ground cooperate to send the encoded signals, enabling the user terminal to realize diversity gain.The simulation results demonstrate that the proposed scheme can provide greatly improved performance.The simulation results in this study show that we can achieve about a 0.8 and 2.3 dB power gain by using the proposed cooperative diversity scheme without and with maximal ratio combining schemes, respectively, compared with the conventional scheme even, with a higher code rate.
