Abstract--Cloud computing has come to the forefront as it overcomes some of the issues in computing such as storage space and processing power. It enables ubiquitous accessing and processing of information without the need of excessive computing facilities. In this work, we plan to brief some of the issues in aggregating the cloud services, discovering futuristic cloud service requests, develop a repository of the same and propose an agent based Quality of Service (QoS) provisioning system for cloud clients. Index Terms—Aggregation, Futuristic cloud services, Repository.
deployment of services across multiple cloud providers, Service Level Agreement (SLA) negotiation and management between cloud providers, additional privacy, security and trust management layers atop providers and support of context-aware applications. Works in [1-5, 15-27, 11-14] depict that not much attention is paid in monitoring and developing repository of cloud services, customized aggregation of services and distribution of services. The field of software agent technology is a rapidly developing area of research which encompasses a diverse range of topics and interests [31-37]. Cognitive agents that mimic human thought process and represent the logical transition of research on human information processing to practical application are deployed to develop an autonomous aggregating system. Section 2 presents the literature survey and section 3 describes the objectives of the research to be carried out. Section 4 describes the proposed methodology and section 5 provides the possible outcome and conclusion.
With the rapid development of processing and storage technologies and the success of the Internet, computing resources have become cheaper, more powerful and more ubiquitously available than ever before. This technological trend has enabled the realization of a new computing model called cloud computing, in which computing resources such II.

Discovery of cloud services The cloud providers are networked by segmenting or clustering them based on type of services provided, geographical locations etc. Cognitive agents crawl blindly through the cloud to discover the cloud services fulfilling the futuristic requests and build the repository of services. Further request prediction may be done using log record, click stream record and user information or Markov model to anticipate futuristic requests for discovering the cloud services. Discovery process may be carried out in parallel using the concept of agent cloning. Repository shall be updated at regular frequency to eliminate the stale information using aging techniques. Multidimensional data structure shall be deployed to store the cloud services in the repository. Efficient indexing algorithms and meta-services (service cache) shall be adopted to retrieve the service information from the repository to improve the performance of the repository access. The repository shall store the services offered, vendor details, pricing, current status, QoS etc. B. Aggregation of requested services Based on the service requests from cloud clients cognitive agents monitor the status of the services, negotiate with the vendors, and aggregate them based on the specified QoS. Unsupervised learning mechanism may help the agents to negotiate intelligently for better prices to aggregate and distribute the cloud services. English auctions may be used to maximize the profits for vending the services. Multiple options of aggregated services are to be given to the clients in order to increase their satisfaction level. C. Distribution of services After the services are aggregated they are to be distributed in a customized way. Scheduling has to be done in an optimal way so as to maximize the availability and utility of services. Billing and pricing algorithms are to be developed for the delivered services. All the above objectives will be simulated under various scenarios to assess the performance and effectiveness of the proposed scheme. The simulation shall be carried out on IBM Blade Center HS22 using compatible programming language. V. POSSIBLE OUTCOME AND CONCLUSIONS Services on the cloud are plenty but the clients are not able to get the required services. There is no common repository of availability of cloud services. The proposed work will develop a framework to overcome the above mentioned issues. Further the usage of cognitive agents offers several benefits in aggregating cloud services such as autonomy in discovering the cloud services, developing and updating the repository, embedding intelligence, flexibility in negotiation, adaptability to network environments, customization of QoS requirements etc. The research work may be enhanced in future by employing some agent based solutions to other issues such as cloud management, enablement, and interoperability and to develop some applications. Further we have planned to publish our research 118 © 2013 ACEEE DOI: 03.LSCS.2013.1.560
