ENERGY EFFICIENT ROUTING PROTOCOL LEACH FOR WIRELESS SENSOR NETWORKS

Abstract

In Wireless Sensor Network Data Aggregation is an important technique to achieve power efficiency in the sensor network. Sensor node has limited battery power so data aggregation techniques have been proposed for wireless sensor networks. A challenge to data aggregation is how to secure aggregated data from disclosing during aggregating process as well as obtain accurate aggregated results. The proposed approach includes a security mechanism, and an innovative cluster head election mechanism and the route will be selected with less energy needed. The simulation output shows that the Low Energy Adaptive Clustering Hierarchy (LEACH) has the security, energy efficiency and prolongs the network life time is high when compared to DSDV and AODV, respectively. In this case, data fusion is helpful to reduce the amount of data transmitted between sensor nodes and base station. The LEACH protocol is an elegant solution to this problem.
