摘　　要：无线传感器网络一般采用分簇路由协议实现数据的汇聚,这类协议要求Sink节点的位置固定,并通过节点间多跳接力传输,将数据汇聚到Sink节点。由于网络中不同节点承担中继的负载不同,这会导致某些负载过重的节点能量提早耗尽,从而形成网络空洞。虽然某些路由协议在网络能耗均衡方面做了一定的措施,但仍无法较好的解决该问题。为此提出一种能耗均衡的动态数据汇聚方法,该方法的汇聚节点(Sink)为可移动节点。为平衡网络能耗,利用网络节点的能量为Sink节点确定若干个数据汇聚位置,并结合TSP算法规划Sink节点的最佳移动路径。通过对该算法进行大量的仿真,并与现有的一些方案进行比较,验证了该算法在各种性能指标上的有效性。In wireless sensor networks,clustering routing protocol is generally used to achieve data aggregation.This kind of protocol requires that Sink nodes have fixed location and transmit data to Sink nodes through multi hop relay.Due to the different load of relay carried by different nodes in the network,this will lead to the premature energy exhaustion of some nodes with excessive load,thus forming a network hole.Although some routing protocols have done some measures in energy consumption balancing,they still can’t solve the problem.In this paper,a dynamic data aggregation method based on energy balance is proposed.The aggregation node of this method is a mobile node.In order to balance the energy consumption of the network,the energy of the network nodes is used to determine a number of data aggregation locations for Sink nodes,and the optimal mobile path of Sink nodes is planned with TSP algorithm.Through a large number of simulations,and compared with some existing schemes,the effectiveness of the algorithm in various performance indicators is verified.
