A Study on Reducing the Power Consumption of Wireless Sensor Networks

Bhukya Venkanna; Kamalesh. V. N.; Banothu John

A wireless sensor network with a large number of sensor nodes can be used as an effective tool forgathering data in various situations. One of the major issues in wireless sensor networks is developing an energy-efficient routing protocol which has a significant impact on the overall lifetime of the sensor network. This paper focuses on reducing the power consumption of wireless sensor networks. Therefore, a communication protocol named LEACH (Low-Energy Adaptive Clustering Hierarchy) is modified. We propose a clustering routing protocol that partitions the network into clusters; the cluster contains, CH, sub-CH (the node that will become a CH of the cluster in case of CH dies), cluster nodes; thus extends network lifetime. We have conducted simulation-based evaluations to compare the performance of the proposed protocol against Low-Energy Adaptive Clustering Hierarchy (LEACH). Our experiment results show that this protocol outperforms LEACH in terms of network lifetime and power consumption minimization.
