Maximum lifetime communication model of wireless sensor network
无线传感器网络最大生命期通信模型研究

This paper presented a new maximum lifetime communication model of wireless sensor network. Discussed the maximum lifetime of wireless sensor network with multiple sources, multiple paths, multiple sinks deeply. It delivered the data generated by source node to multiple paths and reached multiple sinks in order to balance the flow distribution. According to the energy constraints and data traffic conservation of wireless sensor networks, formulated the problem as a liner program (IP)problem by maximizing the lifetime at which the first node ran out of energy and reduced the amount of data passing the node for the suboptimal goal. Relying on the optimization of a distributed algorithm, the IP could be resolved. It verified the performance of communication model in multi-base station environment by simulation. The result shows that the network lifetime can be maximized in communication model.
