TDMC:长距离无线MESH网络中面向流量比的动态多信道MAC协议
TDMC: TRAFFIC FRACTION-ORIENTED DYNAMIC MULTI-CHANNEL MAC PROTOCOL FOR LONG-DISTANCE WIRELESS MESH NETWORKS
摘要
Abstract
IEEE 802. 11-based long-distance wireless mesh networks (Ldmesh) is a long-distance wireless transmission technology. Recently, TDMA-based MAC protocol becomes the focusing topic in Ldmesh. Existing single-channel MAC protocol has the problem of low link utilization and there is no feasible multi-channel MAC protocol. This paper presents TDMC, a distributed, real-time, traffic fraction-oriented dynamic multi-channel MAC protocol. TDMC is based on real-time traffic fraction, follows the proposed channel allocation rules and uses a viable division interval method for dynamic allocation of channels. Simulation results show; TDMC performance is significantly better than JazzyMac. When we use the medium load, TDMC performs better than the static multi-channel protocol by 15% -54%.关键词
