Energy Efficient Clustered Routing for Wireless Sensor Network

摘要

In a Wireless Sensor Network (WSN) hundreds of tiny sensors with limited resources are accommodated to sense the information from the field. Transfer of gathered information from the sensing field to the base station must be done in proficiently to sustain the network longer. Clustering of sensor nodes is one way to achieve this goal. This paper introduces an Energy Efficient clustered routing protocol based on LEACH-C for WSN. In LEACH-C (Low Energy Adaptive Clustering Hierarchy-Centralized), the cluster heads are selected by the base station randomly. This paper introduces a novel cluster based routing protocol in which, the base station finds the highest energy node among the cluster and mark it as a cluster head for the current time. Thus in the proposed system the energy consumption of various nodes becomes more uniform as compared to LEACH-C. The simulation results indicate that our proposed method leads to efficient transmission of data packets with less energy and therefore increases the network longevity as compared to LEACH-C and LEACH.
