Abstract
Wireless Sensor Networks (WSNs) have gained growing attention from both the research community and actual users. The lifetime is a critical parameter for Wireless Sensor Networks (WSNs). As Wireless Sensor Network is a system which allows communication among the nodes which have different parameters like battery, transreceiver, sensor etc. This paper focuses on battery part of the node and the efficient utilization of energy source, that is, battery in sensor node to reduce the energy consumption of nodes, so that the network lifetime can be extended. Most previous sensor network lifetime enhancement techniques focused on the uniform battery allocation among homogeneous nodes.
This paper focuses on improving wireless sensor network lifespan with heterogeneous spatial power consumption distributions with Lossless Sleep Doze Coordination (LSDC) protocol. This paper gives solution to the lifetime–aware battery allocation problem for sensor networks with heterogeneous power distributions. We have conducted simulation based evaluation to compare the performance of the proposed heterogeneous spatial power consumption distributions with LSDC protocol against homogeneous distributions.
