摘要: 采用跨层技术,提出一种无线传感器网络(WSN)中基于分簇的实时传输算法。在WSN中找出簇头到基站的多条优化路径,采用基于平均队列长度的拥塞控制方法,在这些路径中找出一条耗能最小且实时性最优的路径,并沿着该路径将数据传送到基站。仿真分析表明,该算法能满足网络的实时性需求,并能有效进行拥塞控制。

Abstract: Using the cross-layer technology, this paper presents a real-time transmission algorithm based on clustering in Wireless Sensor Network(WSN). It identifies more than one optimal paths for each cluster head to the base station. It selects an optimal path from the paths with congestion control method. The data will be sent to the sink along this path. Simulation analysis shows that the algorithm provides real-time transmission and conducts congestion control effectively.

Key words: real-time transmission, cross-layer technology, clustering, routing table, congestion control
