Optimization of energy in wireless sensor networks using clustering techniques

Wireless Sensor Network Consists of large number of sensor nodes, which are connected through wireless medium has emerged as a ground breaking technology, which offers the ability to measure the physical world parameters accurately. Currently there are some special type of routing protocols are designed for sensor networks. Almost all of these routing protocols have considered the energy efficiency as the objective in order to maximize the life time of the whole sensor network. So far the existing routing protocols available in Wireless Sensor Networks (WSN) are data centric, hierarchical, and location based and on demand routing protocols. As WSN consists of a collection of application specific sensors, the effective use of energy requires efficient routing protocols. The cluster based protocol are Deterministic energy-efficient clustering (DEC), SEP SEP-E are most suitable in terms of energy efficiency Hence in this paper performance evaluation of clustering enhancement of SEP (stable election protocol enhancement) is compared with DEC and SEP, and the simulation parameters were measured for no of nodes Vs average residual energy. It has been observed that the average residual energy in SEP-E have more energy available than DEC and SEP protocol. The Results shows the performance of SEP enhancement protocol is better than other existing protocols.
