Multi-hop Transmission Applied in Wireless Network

Wireless sensor network consists of a large number of nodes with limited energy. As the wireless sensor nodes´ battery cannot be replaced, therefore, reducing energy consumption, improve the node survival rate of the wireless sensor networks is one of the key issues. In this paper after analyzing the present routing protocol based on clustering, it proposes a new improved routing protocol which is cluster-based low-power adaptive routing protocol based on cluster head when transferring data using multi-hop technology in order to evenly assign the cluster head energy and realize load balance. Simulation results show that the improved scheme is better in prolonging the network lifetime.
