ENERGY CONSUMPTION OPTIMIZATION IN WIRELESS SENSOR NETWORK FOR ENVIRONMENT MONITORING

Abstract

Wireless sensor network (WSN) has become increasingly common in several fields of human endeavors requiring information gathering and prediction in both military and civil operation. This work has presented modified energy efficient cluster based routing in wireless sensor network for environment monitoring. The scheme uses hierarchical routing protocol technique which is based on the fact that energy used for long transmission of message is very much greater than energy required for sending message over short range. A WSN was developed using MATLAB C code and with the proposed scheme simulations were carried out to analyze and investigate the effectiveness of the system in terms of optimum range of clusters required to optimize energy of WSN which revealed that the maximum number of cluster is 54. The variation of energy per round against the number of cluster shows that energy consumed per by each sensor node in the cluster is reduced as number of cluster is increased.  This indicated that with the modified algorithm there is energy consumption optimization in WSN.
