Energy-based Wireless Sensor Network Routing Algorithm

The sensor network has abroad application in both military and civial fields, and one of the core problems of its routing technology. This paper emphasizes on wireless sensor network routing technology based on the environment of the large-scale dense network with the objective of low energy consumption and adapting dynamic network topology change.This paper mainly studies on routing strategy of the static and target moving environment and on routing recovery problem in the wireless sensor network. First, this paper puts up with a self adaptive routing strategy based on energy limit. It could reduce the number of the nodes participating routing work according to broadcasting information, confirm energy optimization route meanwhile grasping local topology information and save the discovering routing cost. Secondly, a routing recovery strategy is also raised in this paper. It could recover the destructive routing period by less energy but not destroy other routing.Thirdly, a recovery sub-area routing protocol is put forward.It avoids route reconstruction by the way of target moving area partition. Moreover, the target moving speed has nearly no influence on energy consumption in this strategy.
