无线传感器网络中高效移动汇点规划算法

摘要

在带有移动汇点(MS)的无线传感器网络(WSN)数据收集应用中,采用基于代理的数据收集模式可以有效缩短MS慢速引起的数据收集延迟问题.以提高WSN数据收集的能量效率和缩短数据收集延时为目标,给出了一种MS轨道规划算法MS-TPA.MS-TPA主要包括RN竞选和MS移动规划两个阶段.剩余能量优先的RN竞选机制能够平衡网络节点的能量消耗,MS移动规划算法能够缩短数据收集的延迟问题.仿真实验验证了所提出算法的有效性.%For the data collection in wireless sensor network with mobile sinks, rendezvous based scheme can reduce latency significantly. Aimed at improving energy efficiency and reducing latency, this paper presents an MS trajectory planning algorithm MS-TPA. MS-TPA mainly includes RN competition and the trajectory planning of MS. The residual energy first RN competition mechanism leads to balanced energy consumption and the trajectory planning algorithm of MS reduces the latency of data collection. The simulation validates its effectiveness.
