摘要
现有的基站移动过程中,事件驱动无线传感器网络启发式算法的主要问题是:只考虑了基站与节点的距离而忽视了其它因素。针对这个问题,提出了一种将启发式算法与移动协助数据收集模式(简称MADG)相结合的方法。首先确定基站何时开始移动,然后选定移动目标区域,在移动过程中考虑网络的负载平衡,降低能量消耗,最后在选定的目标区域内做圆周运动,达到增加网络寿命的目的。实验表明,该算法在增加网络寿命的同时还减少了丢包,效果良好。
The main problem of the existing heuristic algorithm in the process of the base station movement of event driven wireless sensor networks is only considering the distance between base station and node, ignoring the other actual factors. With this problem,this paper proposes a move the heuristic algorithm with the combination of the MADG method. First, determine when the first base station begin to move, consider in the process of mobile network load balancing, reduce energy consumption, and finally do circular motion in the selected target area to achieve the goal of increasing network lifetime. The experimental results show that the proposed algorithm has good effect on increasing network lifetime and reduce the packet loss.
