Empirical Analysis of Energy Efficient Clustering Base Routing Protocols in Wireless Sensor Network

Wireless sensor networks are energy constraint networks. Energy efficiency, to prolong the network for a longer time is critical issue for wireless sensor network protocols. Clustering protocols are energy efficient approaches to extend the network lifetime. LEACH protocol is one of the basic cluster based protocol in wireless sensor network. The performance analysis of energy efficient multi-hop clustering protocols like LEACH, DEEC and EAMR are carried out by considering change in the number of nodes for same network area with respect to the time using Network Simulations (NS-2/NS-3) Software. This is efficiently helps the comparative study of node death rate, energy consumption and network lifetime. Index Terms – Clustering, LEACH, DEEC & EAMR Energy-efficient Protocols
