| 摘 要： | 基于802.11协议MAC层重传策略,提出一个衡量节点接入能力的参数CAM(capacity of access to medium),以体现节点周围信道的繁忙程度及其抢占信道能力。在此基础上,联合MAC层和网络层进行跨层设计,提出了一个拥塞感知路由CAOR(congestion aware on-demand routing)协议。仿真表明:该协议能够在降低开销的前提下,显著增加网络吞吐量,并降低平均端到端的时延。 |
| 关 键 词： | ad hoc网络 拥塞感知 跨层设计 路由协议 |

| Abstract: | A new metric CAM(capacity of access to medium) was presented based on the retransmit strategy of IEEE 802.11 MAC(medium access control) layer protocol.The characteristic of CAM shows that the MAC layer information can be considered as an indication of congestion degree around a node.Furthermore,a congestion-aware routing protocol based on the proposed metric was developed.In addition,simulation results shows that the new approach can improve the network throughput and reduce the end to end average delay with less overhead. |
| Keywords: | ad hoc networks congestion aware cross-layer design routing protocol |
