Title
Node Energy Consumption Analysis in Wireless Sensor Networks
Abstract
The limited sensor node energy and the large number of nodes with dynamic network topology information have always been the important design concerns in Wireless Sensor Networks (WSN). Node clustering is an effective way to tackle with the two issues by grouping the nodes into hierarchies in order to reduce communication distance and the amount of message. This paper mainly focuses on the unification of the node energy consumption in WSN. The distributions of the energy consumption for various scenarios in the hierarchical network are analyzed for the first time and two main reasons are found leading to the asymmetry of the energy consumption among nodes. One is the energy consumption from the communications between nodes and base station, and the other is that from the cluster head for receiving data from other nodes. It is concluded that the probability of the node acting as cluster head should depend on the distribution of the head's energy consumption, and a variable sampling space oriented to the potential number of cluster heads is established thereafter. Furthermore, a new clustering algorithm, the Segment Equalization Clustering based on Cluster Head Energy Consumption (SECHEC) algorithm is proposed, which can effectively improve the network lifetime and ensure the availability of the system within its entire lifespan.
