摘要:

提出了一种基于移动预测模型的稳定链路度量算法,定义了稳定邻居度量和本地运动度量2种测度。根据这2种测度,移动预测模型利用LZ78算法对本地节点与其邻居的稳定性概率进行预测,从而找到其最稳定邻居,为选择稳定路由提供依据。仿真结果表明此算法明显优于直方图算法及最小 ID 算法,所选链路的稳定性能显著提高。

关键词: adhoc网络, 链路稳定性, 稳定邻居度量, 本地运动度量

Abstract:

A mobility prediction model based stable link selection algorithm was proposed in which stable neighbor metric and local movement metric were defined.Mobility prediction model was applied to predict stability probabilities between each local node and its neighbors by using those two metrics and LZ78 algorithm so as to find the most stable neighbor of each local node and most stable route in a route discovery.The simulation results show that the algorithm outperforms the histogram algorithm and the lowest ID algorithm in selecting stable links.

Key words: ad hoc networks, link stability, stable neighbor metric, local movement metric
