Ad Hoc网络路由协议是影响Ad Hoc网络性能的关键技术之一,最优链路状态路由协议OLSR(Optimized Link State Routing)是Ad Hoc网络中常用的协议之一,但是传统的OLSR协议在高负载、节点快速移动的情况下会导致连接中断和数据的丢失。针对上述问题,本文结合卡尔曼滤波移动预测模型对OLSR协议进行了改进,并将改进的协议在GloMoSim上进行了模拟仿真,实验结果证明改进协议在多种情况下都不同程度的提高了网络性能。
Ad Hoc network routing protocol is one of the key technologies that affect the performance of Ad Hoc networks. Optimized Link State Routing (OLSR) is one of the commonly used protocols in Ad Hoc networks. However, the traditional OLSR protocols are widely used in high load In the case of fast node movement, the connection will be interrupted and the data will be lost. In view of the above problems, this paper improves the OLSR protocol based on the Kalman filter moving prediction model, and simulates the improved protocol on GloMoSim. The experimental results show that the improved protocol can improve the network performance under different conditions .
