| 摘 要： | 针对TCP在Ad Hoc网络环境中性能急剧下降的问题,提出一种基于侦听信道连续空闲时隙数的负载自适应退避（LAB）算法。LAB算法通过测量无线信道连续空闲时隙数自适应调节退避窗口,达到优化网络吞吐量的目的。共享一条信道的各节点能在侦听连续空闲时隙数后,收敛到一致的退避窗口。仿真结果表明,与BEB等算法相比,该算法具有更高的网络吞吐量和流间公平性。

| Abstract: | Aiming at the problem that TCP performance declines largely in Ad Hoc networks, this paper develops a Load-Adaptive Backoff(LAB) algorithm, which based on monitoring the number of consecutive idle slots. By measuring the number of consecutive idle slots, LAB algorithm is capable of optimizing network throughput through adjusting content windows adaptively. The consecutive idle slots help the nodes who share a common wireless channel converge to a coincident backoff window after monitoring the number of cons... |
