单载波WMN中跨层拥塞反馈算法研究
Research on Cross Layer Congestion Feedback Algorithm in Single Carrier WMN
摘要
Abstract
In single carrier Wireless Mesh Network(WMN), congestion feedback is a key factor to system performance. This paper presents a Cross Layer Congestion Feedback(CLCF) algorithm. Congestion feedback is used to integrate various protocol layers into a unified framework to be optimized. Different layers carry out distributed computation using local information to achieve individual optimality, that is, to improve the performance of the whole system, congestion control, routing strategy, Media Access Control(MAC) scheduling and Adaptive Modulation Coding(AMC) mode are respectively optimized in transport layer, network layer, link layer and physical layer. Simulation results indicate that the throughput of the proposed algorithm is increased by 18%compared with IEEE802.11 TCP.关键词
