Energy Efficient Stable Election Protocol for Clustered Heterogeneous Wireless Sensor Networks

Abstract

Wireless sensor networks are the networks with wireless sensors disseminated in a region which sense various types of information and then transmit this information to the other nodes or to the final destination. These nodes sense the changes in the physical parameters similar to - temperature, pressure, etc. The data sensed by these nodes are then approved to the Base Station (BS) for estimation. Wireless sensor networks are used for the variety of purposes like military surveillances, habitat monitoring, forest fire detections, landslide detections. This paper presents the new clustering algorithm by modifying SEP (Stable Election Protocol) for heterogeneous wireless sensor network, called EE-SEP. Energy Efficient -SEP protocol is used to increase the number of alive nodes and thereby increasing the energy efficiency, stability period and network lifetime and balancing the energy consumption. Simulation results show that proposed Energy Efficient SEP algorithm performs better as compared to SEP.
