As a kind of new wireless ad hoc network, sensor network has wide applications in the fields of environmental and military monitoring, seism and temperature forecasting etc. Since the nodes＇ energy cannot be supplied in the hostile and severe environments, so it is important to research about how to prolong life of the whole sensor network. On the basis of normal distribution model of sensor nodes, a novel routing protocol with low level of power consumption is proposed, in which, all nodes are divided into sub clusters and sub rings according...
