| 摘 要： | 为了减轻多速率共享问题对无线多跳网络造成的影响,结合路由选路过程中的报文广播,提出基于速率和网络流量进行信道分配的跨层设计方法.该方法提出容量代价函数,设计了信道分配优化模型,在保证新业务带宽需求的同时,降低新业务接入对原有业务的影响,在路由选路过程中实现速率和信道的同时优化.仿真结果表明,该方法使网络吞吐量获得很大提升,同时节省了大量协议开销.

| Abstract: | To reduce the impact of the multi-rate sharing problem on multi-hop wireless networks,combining with the message of the routing process,a cross-layer design method of the channel assignment is proposed based on the rate and the network traffic.It proposes a capacity cost function,and designs an optimized channel assignment model.It reduces the impact of new access service on existing service,while ensuring that the bandwidth requirement of the new service,and then achieves the optimization of the rate and the channel with the routing process at one time.Simulations show that the method greatly improves the network throughput,and saves a lot of protocol overhead. |
