摘要
针对无线网状网络中采用何种路由判据进行路由选择以增大网络吞吐率的问题,在分析现有路由选择准则不足的基础上,通过综合考虑链路的可用带宽、延时、可靠性和干扰等因素对链路QoS的影响,提出了一种新的综合QoS路由准则和算法IRMQOS,并通过仿真验证了该路由准则和算法的可行性。仿真实验结果表明,该方法能显著提高网络吞吐率。
In order to maximize the networks throughput, which routing metric should be used has become a key research problem recently for wireless Mesh networks （WMNs）. On the basis of analyzing the flaws of the existing routing metric, a novel QoS routing metric and algorithm （IRMQOS） are proposed to solve the problem, which integrate the available bandwidth, delay, reliability and multi-channel interference among links. Finally the feasibility of the proposed method is verified with protocol simulation. It is demonstrated in the simulation that the algorithm can improve the network throughput greatly.
