Energy-Efficient Gossiping Protocol of WSN with Realtime Streaming Data

Nowadays, wireless sensor networks (WSNs) are widely used, and various routing schemes have been developed for them. Its lifetime is limited as each node of WSN is battery-powered, and unnecessary data transmissions of the nodes shorten the lifetime of entire network. Gossiping protocol has been recognized as one of the most effective routing schemes employed for WSN. In this paper we propose a new scheme called energy efficient gossiping (E-Gossip) protocol to maximize the lifetime of WSN by properly adjusting the gossip probability and controlling the operation of each sensor node based on the remaining energy. Redundant data transmission is also reduced. The proposed scheme is simulated with NS-2, and the simulation results show that it substantially reduces and balances the energy consumption compared to AODV and the existing gossiping protocol. As a result, the proposed scheme is able to effectively prolong the lifetime of WSN.
