Wireless sensor network consists of application oriented and cheap micro-devices called sensors nodes having potential of connecting the physical world with virtual world by their sensing abilities. These sensor nodes are having restrained battery sources. Efficient energy management is current area of research in wireless sensor networks. Here they advise one such energy aware multi-hop protocol (G-DEEC) for two level heterogeneous networks. In G-DEEC (Gateway based Distributed Energy Efficient Clustering), the base station is placed out of sensing area and rechargeable gateway nodes are placed inside field with other randomly deployed sensor nodes. Simulation shows the proposed protocol G-DEEC is better than single-hop DEEC in terms of number of half dead nodes and dead nodes; thereby showing improvement in network lifetime and stability.
