基于TDMA的分布式全双工链路调度算法研究
Study of a Distributed Link Scheduling Algorithm in TDMA Networks Using Co-time Co-frequency Full Duplex
摘要
Abstract
Traditional wireless Ad hoc networks have the problem of poor network performance under the circum-stances of high traffic load. To solve this problem,a distributed full duplex MAC protocol,which combines TDMA and CCFD together,is proposed. In this protocol,all nodes need to do suppression inspecting according to link co-existing schemes before data transmission begins.Then,primary TDMA links start searching secondary links according to the schedu-ling priority,and send out corresponding requests. The four times hand-shaking process of scheduling process is accom-plished within the head of the traffic slot.With no affect on the half-duplex transmissions of traditional TDMA networks,it can increase as many links coexisting with originla links in the same slot as possible.The simulation results show that this protocol actually improves throughput and time delay performances of the wireless Ad hoc networks.关键词
