摘要: 在无线传感器网络(WSN)中,由于节点能量与通信距离的限制,节点间的通信会出现间隙性,甚至产生分裂网络。为此,采用消息摆渡的方法构造网络吞吐率的数学规划问题并进行仿真。实验结果表明,节点的缓存空间、感知速率不影响整个网络的吞吐率,网络吞吐率随摆渡节点移动速度的加快而提高。

Abstract: Wireless Sensor Network(WSN) is prone to partitioning due to limited energy in sensor nodes and unreliable radio communications between them. Aiming at the problems of partitioned WSN, this paper uses Message Ferry(MF) based data gathering schemes, a programming problem is developed by introducing two parameters, which optimizes bits of unit time reaching the sink(network throughput). Experimental results show that network throughput does not affected by ferry speed and memory capacity of nodes, the greater speed of ferry is, the more network throughput is.

Key words: Wireless Sensor Network(WSN), partition, data gathering, Message Ferry(MF), throughput
