Distributed Energy Efficient Heterogeneous Clustering in Wireless Sensor Network

Wireless Sensor Networks (WSNs) are composed of a large number of sensor nodes with the ability to sense and process data in the physical world in a time sensitive and time restrained environment. The sensor nodes contain power constraint which limits the network lifetime and they are not practically viable to recharge frequently. Clustering enables efficient resource allocation and is a key technology to extend the network lifetime. The main idea of this paper is focused on the performance evaluation of Enhanced Developed Distributed Energy Efficient Clustering (EDDEEC) Algorithm which employs an energy aware three level heterogeneous clustering protocol in wireless sensor network. EDDEEC implementation was performed using the MATLAB simulator as it provides good scalability unlike other simulators. The analysis of EDDEEC algorithm gave birth to a new energy-aware algorithm called modified distance based EDDEEC and the comparative analysis shows that the modified EDDEEC outperforms 42% over the existing EDDEEC protocol.
