HETEROGENEOUS PROTOCOLS FOR INCREASING LIFETIME OF WIRELESS SENSOR NETWORKS

Abstract

In this paper, the heterogeneous energy-efficient data gathering protocols for lifetime of wireless sensor networks have been reported. The main requirements of wireless sensor network are to prolong the network lifetime and energy efficiency. Here, Heterogeneous - SEP: A Stable Election Protocol for clustered heterogeneous (H-SEP) for Wireless Sensor Network has been proposed to prolong the network lifetime. In this paper, the impacts of heterogeneity in terms of node energy in wireless sensor networks have been mentioned. Finally the simulation result demonstrates that H-SEP achieves longer lifetime and more effective data packets in comparison with the SEP and LEACH protocol.
