摘要： 在MANET接入Internet的网络环境中,由于移动节点集中使用某些位置上的网关来实现接入,造成这些网关的负载增加,性能下降.为了能够均衡利用网关及各移动节点,提出了一种新的利用动态网关和多径技术实现MANET接入Internet负载均衡的路由机制.该机制使用多路径进行传输,并在多个候选路径之间按一定的比例均衡分配通信流量;同时,在选择网关时尽量选择低负载的网关,均衡网关的负载.仿真分析结果表明:该算法能有效降低分组的平均传输延迟并提高网络的吞吐率.

Abstract: For the MANET accessing Internet, some gateways are in certain positions where the mobile nodes (MNs) are used intensively to access Internet so as to cause heavier loads at those gateways and weaken their performance. A load-balanced routing mechanism and relevant algorithm are therefore developed for MANET accessing Internet with dynamic gateways and multi-paths. This algorithm uses multi-path for transmission and assigns communication traffic to many candidate paths in accordance to a certain proportion and, meantime, it balances the load of gateways by choosing them to which the load should be as low as possible. The result of simulation analysis showed that this algorithm can reduce the average transmission delay of packets and improve the throughput of the networks effectively.
