An improved Clustering Based Hierarchical Protocol for extending Wireless Sensor Network Lifetime – EG LEACH

Abstract

Wireless sensor networks play a vital role in present day world which are being used in different types of applications and occupy an important part in networking domain. It comprises of number of sensor nodes of limited battery power due to which saving power becomes the main factor to be considered in this finite energy wireless sensor networks to increase its lifetime. It is fact that in clustering protocol energy consumption by cluster head node (CHN) during communication with the BS is much higher than energy depletion by cluster member nodes (CMN) to transmit data to the associated cluster head (ACH). Therefore, energy consumption by cluster head and other member nodes become a crucial factor to be discussed for determining wireless sensor networks (WSNs) lifetime. This proposed protocol organises the cluster head selection efficiently to provide longer network lifetime and to provide balanced cluster head selection. The simulated output shows better performance comparing with traditional LEACH.
