摘要
AdHoc网络随着网络负荷的增加,局部的拥塞是导致网络性能大幅下降。采用修改的AODV路由协议,结合链路层的分析,提出了一种节点负载分流的方法。该方法结合了AdHoc网络的特点,采用网络层和链路层相互协作,均衡网络流量,提高了网络的整体性能。仿真结果表明,该改进在不同拓扑变化频率和不同节点密度情况下均明显提高了网络吞吐率,改善了网络拥塞。
The performance ofAd Hoc network degrades quickly with the increasing traffic load with congestion in a single node being the main reason. The modified AODV is adopted, the traffic of link-layer is analyzed, then a traffic-balanced method is proposed. According to the proposed method, network-layer and link-layer cooperates to reduce local congestion. The simulation results show that the method has improved the performance by 25 %-40 %0 under the different node destinies and movement speeds.
