基于全局时延最小化的移动Sink数据收集算法
Data Gathering Algorithm for Mobile Sink Based on the Global Delivery Latency Minimization
摘要
Abstract
For the latency problem brought by the movement of Sink node,this paper presents a mobile Sink data gathering program based on optimal path(OPDG). Firstly,a set of rendezvous points(RP)are obtained by MWHA (Minimum Weighted Heuristic Algorithm)algorithm. Then a best set of access points are selected according to the RP set. Finally,the shortest path is found across the access points. The mobile Sink will travel along this path peri⁃odically and collect data at each access point. Lots of simulation results show that compared with existing algorithm , OPDG algorithm can shorten the delivery latency and prolong the network lifetime.关键词
