摘要
MANET具有网络资源有限、网络中的节点可以任意移动、网络拓扑结构变化迅速等特点,导致了重路由操作的频繁发生,极大地消耗了网络资源,降低了网络性能。网络节点运动的预测在很大程度上有利于解决这个问题。本文首先讨论了MANET的移动特性和链路预测的可行性,然后对各种链路预测的基本原理和方法进行了分析与比较,最后探讨了该问题进一步的研究工作。
Mobile Ad hoc network is a self-organizing and dynamically reconfiguration wireless network, which has scarce radio resource and battery power. These features lead to high frequency of rerouting operation and costing the limited resources, so severely degrade the performance of Ad hoc networks. The mobility prediction can contribute to efficiently solve this problem. In this paper, we study the mobility features of Ad hoc networks and the feasibility of the mobility prediction, then the comparisons and analyses of these prediction schemes are made with simulations. Lastly, further research works are presented.
