As ad-hoc network, wireless sensor networks (WSN) have become increasingly common in several fields of human endeavours requiring information gathering and prediction in both military and civil operation. This work has presented modified energy efficient cluster based routing in wireless sensor networks for environment monitoring. The scheme introduces two level hierarchical routing protocol involving an active cluster head (CH) and associated cluster heads (CHs) that make up a head-set. A WSN work model 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 at number of cluster 20 to 54, the energy consumption by the network was approximately the same. Thus, the maximum number of cluster was 54 because beyond this number the energy of the sensor nodes was zero. The maximum number of headset was 5. The variation of energy per round against the number of clusters showed that energy consumed per round by each sensor node in cluster is reduced as the number of clusters is increased.

Abstract


As ad-hoc network, wireless sensor networks (WSN) have become increasingly common in several fields of human endeavours requiring information gathering and prediction in both military and civil operation. This work has presented modified energy efficient cluster based routing in wireless sensor networks for environment monitoring. The scheme introduces two level hierarchical routing protocol involving an active cluster head (CH) and associated cluster heads (CHs) that make up a head-set. A WSN work model 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 at number of cluster 20 to 54, the energy consumption by the network was approximately the same. Thus, the maximum number of cluster was 54 because beyond this number the energy of the sensor nodes was zero. The maximum number of headset was 5. The variation of energy per round against the number of clusters showed that energy consumed per round by each sensor node in cluster is reduced as the number of clusters is increased.
