A Multi-hop Routing Protocol Based on Fixed Radio Wave in Wireless Sensor Network

Recently, in order to improve the energy efficiency of WSN(Wireless Sensor Network), widely research have been carried on. But, up to the present, all presented methods are based on direct communication between CH (cluster head) and sink node, and based on the assumption that node can intelligent regulate signal energy according to the distance between nodes. So it´s hard to implement those methods. Based on the theory that node has fixed radio wave radius, this paper present a multi leveling routing protocol from one sink node to all other nodes. According to the simulation of the presented protocol, we have proved the energy saving efficiency and the implementation in real WSN.
