Abstract

In recent years, many location-a ware routing protocols have been proposed for the mobile ad hoc networks. The routing performance is improved by exploiting the position information of the mobile nodes. However, the mobility characteristics of the mobile nodes have not been taken into consideration. In this paper, the proposed predictive mobility and location-aware routing (PMLAR) algorithm incorporates the moving behaviors of the mobile nodes in the protocol design. The region for packet forwarding is determined by predicting the future trajectory of the destination node. The routing performance can be effectively improved by adopting the prediction mechanism of the proposed PMLAR algorithm. Simulation results show that the PMLAR algorithm outperforms other routing protocols under different network topologies.

移动自组织网络中的预测移动性和位置感知路由协议
近年来,针对移动自组织网络提出了许多位置路由协议。利用移动节点的位置信息,提高了路由性能。但是,没有考虑到移动节点的移动性特性。本文提出的预测移动和位置感知路由(PMLAR)算法在协议设计中考虑了移动节点的移动行为。通过预测目的节点的未来轨迹来确定报文转发的区域。采用PMLAR算法的预测机制可以有效地提高路由性能。仿真结果表明,在不同的网络拓扑下,PMLAR算法都优于其他路由协议。
