An Energy Efficient Clustering Algorithm for Increasing Lifespan of Heterogeneous Wireless Sensor Networks

Abstract

Wireless Sensor Network is a network of sensor nodes that are deployed in some geographical area or concerned entities for monitoring of physical conditions. Environmental sensing, health care monitoring, border surveillance, forest monitoring is some of the application areas of wireless sensor networks. Sensory nodes sense relevant data which will be forwarded to base station. Wireless sensor nodes are remotely deployed therefore they may remain unattended for long. The energy utilization is thus a key challenge in wireless sensor network. Various algorithms have been proposed for efficient energy utilization in wireless sensor network. Most of them are clustering based algorithms that provides solution for energy efficiency and hot-spot problem. This paper introduces a clustering algorithm which is energy efficient and increases lifetime of Heterogeneous WSN. In our proposed algorithm cluster-heads are selected in an effective way and size of the clusters is variable and is calculated on the basis of energy and distance. Then the data is transmitted using chaining. Simulation study shows that our proposed algorithm is performing better than DEEC and LEACH protocols. Our proposed algorithm is increasing the overall network’s lifespan and transmitting more packets of data to base-station than LEACH and DEEC algorithm.
