Energy Efficient Routing Protocol in Wireless Sensor Network

Routing protocol is one of the most important methods to reduce and balance energy consumption in Wireless Sensor Network. Three schemes are proposed in this paper aiming to reduce nodes' energy consumption and extend the lifetime of the network, including communication distance minimization, substitutable nodes sleeping and child nodes balancing. At last, simulation and analysis is given, which shows that the above three schemes have much better performance than LEACH in terms of lifetime of the whole network.
