Abstract

Wireless sensor network (WSN) is an ad hoc network in which each sensor is defined with their limited energy. In WSN nodes are deployed into the network to monitor the physical or environmental condition such as temperature, sound, vibration at different location. Each node receives the information (data) and then transmits to the base station. In this paper we are analyzing each sensor consumes some energy in receiving or sending the data over the network. The lifetime of the network depend on the energy spent in each transmission. So we need an energy efficient protocol that plays an important role in offering high energy efficiency and long span of network lifetime. One of such protocols is PEGASIS; it is a near optimal chain-based routing protocol. This protocol starts forming a chain using Greedy algorithm then randomly selects a chain leader for the formed chain after that data transmission takes place. In PEGASIS, it takes the advantage of sending data to its closest neighbor. It save the energy for WSN and increases the lifetime of the network. In this project work, we analyses an energy efficient routing protocol, it achieves energy conservation and reduc

Introduction

Wireless sensor network is most important technologies in recent years. In past years it has received big attention from both academic and industry in the world. A WSN typically lies of a huge number of low-cost, low-power, and multifunctional wireless sensor nodes, with sense, wireless communications and computation abilities. WSN has a many application like a monitoring, environment, military surveillance, and industrial process control. In some WSN application, the distribution of sensor node is acted in ad hoc style less certain planning and engineering. Once the sensor different attacks at different layers and its counter measure. In section IIIliterature survey, related work of some existing approaches and finally in section V we present the conclusion of our work node has been distributed, it must be able to automatically create itself into a wireless communication network.

Conclusion

In this paper, one of the main challenges in the design of routing protocols is energy efficiency due to the limited energy resources of sensors in WSN. Routing protocol can effectively increase WSN performance using efficiently utilizing energy of sensor node. Therefore, routing protocols designed for WSNs should be as energy efficient as possible to prolong the lifetime of individual sensors, and hence the network lifetime. Because of this reason PEGASIS protocol can be selected for better performance in terms of energy efficiency and network life time. PEGASIS overcome the issues of WSN. Hence future work may be well focused on modifying or improved PEGASIS routing protocols such that the improved PEGASIS protocol could minimize energy of the sensor network and extended the lifetime of network.
