针对adhoc网络,提出了基于拓扑透明特性的混合MAC协议——TTHM协议(topology-transparent hybrid MAC protocol).TTHM协议在T-TSMA(threaded time spread multiple access protocol)协议所提出的螺纹协议机制的基础上引入了混合接入策略,能够根据当前的网络拓扑与业务负载,有效利用节点的分配与未分配时隙来进行报文传输.由于TTHM协议具有拓扑透明特性且克服了最大节点密度限制,因此便于分布式应用.仿真结果表明,TTHM协议比T-TSMA协议表现出更好的性能优势.
Aimed at adhoc networks, a topology-transparent hybrid MAC protocol based on topology transparency is proposed.TTM protocol is based on the threaded protocol mechanism proposed by the T-TSMA (threaded time spread multiple access protocol) protocol Introduces a hybrid access strategy that enables efficient use of node allocation and unallocated time slots for packet transmission based on the current network topology and traffic load.Because the TTHM protocol has topology transparency and overcomes the maximum node density constraints Which is convenient for distributed applications.The simulation results show that the TTHM protocol shows better performance advantages than the T-TSMA protocol.
