摘要
利用跨层设计的思想,论文提出了一种自适应多速率机制下,基于节点信息的AdHoc路由算法。根据物理层SNR的测量,结合MAC层的信息进行延迟估计,引入一种新的路由度量来选择路径,避开拥塞,减少延迟,提高网络吞吐量,从而能改善网络的整体性能。
This paper proposes a cross-layer routing scheme based on information monitored by nodes for Ad Hoe networks supporting multi-rate mechanism.A new routing metric is introduced to take SNR measure on physical layer and delay estimate on MAC layer into account.With this metric,the routing algorithm tends to choose routes with wider bandwidth,lower delay,and less congestion.It demonstrates that the proposed scheme improves the performance of Ad Hoe work.
