wireless sensor network enabled devices. While discovering new contacts energy consumptions should also be monitored of wireless sensors networks equipped devices at different parameters. Different parameters are mobility conditions of devices, adopted Discovery Algorithm, stochastic characteristics of encounters. The main goal is finding an optimal solution for discovering new contacts in limited energy budget of devices. The one way introduction of duty cycle to make radio interfaces active according to need while neighbor discovering. The second way can be minimizing the packet delivery time there by conserving the energy of devices..
1.ALWAYS ON:When radio interface are active during this state. 2.ALWAYS OFF:When radio interfaces are inactive during this state.
1.2 Duty cycle:Duty cycle is defined as a period of time in which device is operated in one complete set of predefined time.
1.3Packet delivery time:Packet delivery time is defined as
Key Words: Neighbor Discovery, Packet Delivery Time,,duty cycle,cluster head,mobile sink,energy .
the time taken by packets to reach from source to destination.
1.4Different methods:In this paper various methods are
1.INTRODUCTION
described in which the duty cycle and time to deliver the packet are seen respectively. This two factors are major concern for any wireless sensor network devices which effects the energy budget of the devices.
Unnecessary energy expenditure is a very critical issue in wireless sensor networks [2]. A main reason for this, is the selection of long paths for data transmission. Short range wireless interfaces such as WIFI, Bluetooth Smart phones can communicate with each other and other devices which are there in their range of communications. Interest is there is no special infrastructure require for communication. But real world conditions are different. Among this conditions the very basic condition is energy budget of device. High Cost is needed every time for process of discovering new nodes. Periodically checking for new nodes is an extremely energy consuming operations(Polling)[1].Every time there is less chances that interested nod is taking part in process. Keeping every time radio interfaces on also impacts on energy budget of devices. Introduction of duty cycle s good but most of the times encounters of nodes are unpredictable. Introduction of packet delivery[4] time concept yet another approach so that if packet delivery time is less the energy saving can be enhanced greatly.
2. PROBLEM STATEMENT What is better:A longer discovery processes with high contact loss probablity or shorter discovery processes with low contact loss probality and energy budget of this used methods.Answer clearly depends upon stastics of various methods.[3]
2.1MAIN CONTRIBUTION 1. Formalizing the number of contacts to be discovered. 2. Formalize the amount of energy budget and consumption required for discovering new contacts. 3.Analysis of various methods used for making duty cycle of mobile devices for communication efficient so that in less amount of energy more peers can be discovered. 4.Analysis is based on the experiments done on the mobile devices using various duty cycle algorithms.
