移动Ad Hoc网络模糊逻辑移动预测路由算法

移动自组网是一种能够支持多跳的临时性计算机通信网络.它由一组带有无线收发装置的移动节点组成.节点能随机任意移动,可导致拓扑的动态变化,会对路由的稳定性乃至网络的整体性能产生重要的影响.通过对节点运动速度和运动方向的观察,使用模糊逻辑控制策略,提出了一种基于模糊逻辑预测链路稳定性的路由算法.仿真结果表明,该协议有效地提高了数据连接的平均存活时间、链路的数据传输率和端到端的吞吐量,同时减小了端到端的延迟和控制的开销.

Fuzzy Logic Mobility Prediction Routing Algorithm for Mobile Ad Hoc Networks

The mobile ad hoc network (MANET) is a temporarily organized computer multi-hop communication network which is composed of mobile hosts equipped with wireless transmitters and receivers. These hosts can move at will, which results in a highly dynamic topology and imposes significant effect on the route stability and overall performance of the network. Based on the observation of the velocity and direction of these mobile hosts, this paper proposes a routing algorithm which can predict the link stability with fuzzy logic. The simulation results have proven that this protocol works well in extending the average lifetime of data connections, in increasing the data rate as well as the end-to-end throughput, and in decreasing the end-to-end latency and overhead substantially.
