| 摘要: |
| 移动Ad Hoe网络(MANET)中的路由算法应尽量使网络负载均衡，不均衡不仅导致正在通信的路由由于过度拥塞而引起数据包延时过大、吞吐量下降，而且会使拥塞节点的能量提前耗尽，从而加剧网络拓扑结构的变化及节点之间的不公平性。本文对目前提出的一些负载均衡路由算法进行了简要比较和分析，在此基础上，指出了目前负载均衡路由算法中存在的一些问题，并提出了一个实现负载均衡路由算法的一般模型。基于该模型，文中提出了一种简单的负载均衡路由算法。仿真结果表明，负载均衡路由算法比未考虑负载均衡的路由算法具有更高的数据包投递率和更低的数据包传输延时。 |

| Abstract: |
| The routing algorithm in a mobile Ad Hoc network (MANET) should try to balance the network load. Load imbalance not only leads to the greater packet transmission delay and smaller network throughput but also makes the over congested nodes power exhausted, which results in more severe topology changes and unfairness of the nodes. This paper briefly presents and compares prior proposed load balance routing algorithms. Based on the comparison and analysis, this paper introduces the related important problems about the load balance routings and proposes a general model for the load balance routing algorithm. Based on this model, it brings forward a simple load balance routing. Simulation results show that the load balanced routing can improve packet delivery ratio with less end-to-end delay. |
