提出了一种跨层设计及路径质量感知的移动自组网(MANET)自适应Internet接入策略.综合考虑网络剩余带宽、投递率以及节点负载等因素,设计一种综合多目标性能参数的路由判据,均衡网络负载,满足互联时多媒体业务的服务质量需求.同时,根据网关负载和网络拓扑情况自适应调整网关通告的广播范围和发送间隔,实现网关的最佳覆盖.仿真结果表明,该算法能有效提高网络的互联性能,并保持合理的控制开销.
This paper proposes a mobile ad hoc network (MANET) adaptive Internet access strategy with cross-layer design and path quality perception. Considering factors such as residual network bandwidth, delivery rate and node load, this paper designs a routing algorithm based on multi-objective performance parameters Criterion to balance the network load to meet the service quality requirements of multimedia services in the interconnection.At the same time, according to the load of the gateway and the network topology, the broadcast scope and sending interval of the gateway advertisement can be adaptively adjusted to achieve the best coverage of the gateway.The simulation results show that The algorithm can effectively improve the interconnection performance of the network and maintain a reasonable control overhead.
