摘要
针对移动信宿(Mobile Sink,MS)的簇化无线传感网络(Wireless Sensor Networks,WSNs),提出优化移动信宿(Mobile Sink,MS)在各簇内的停留时间(Mobile Sink Sojourn Time Optimization,MSSTO)算法。MSSTO算法通过优化MS在各簇内的停留时间,进而平衡各簇头的能耗。MSSTO算法引用一个静态信宿和一个移动信宿,且移动信宿依据Fermat螺旋路径移动。先估计在簇内的停留时间,然后利用整数线性规划(Integer Linear Programming,ILP)优化在簇内的停留时间。仿真数据表明,提出的MSSTO算法降低了能耗,并延长网络寿命。
For cluster-based wireless sensor network,Mobile Sink Sojourn Time Optimization(MSSTO)Scheme is proposed in this paper.MSSTO aims to optimize the sojourn time of Mobile Sink(MS)in each cluster in order to achieve balanced lifetime of Cluster Header(CHs)belonging to different layers of the network.Two sinks are employed,respectively,a static sink and mobile sink.And the mobile sink move on a Fermat spiral path.MSSTO first compute the sojourn time,and the sojourn time is optimized by Integer linear programming(ILP).Simulation results show that the proposed MSSTO reduce the energy consumption,and long the network lifetime.
