摘要
本文针对移动自组织网络中实时业务特殊的服务质量(quality of service,QoS)需求,提出了一种新的媒体访问控制(media access control,MAC)协议,即基于公平的时分多址(fair-time division multiple access,F-TDMA)协议。该协议采用特定的时隙分配算法,来确保实时业务的QoS需求,并兼顾数据业务的接入性能。OPNET仿真表明:F-TDMA协议较现有协议具有较低的接入时延和较高的吞吐量,并且针对不同的业务类型F-TDMA协议可以优先确保实时业务的接入性能,同时又不会使数据业务的接入时延过大而失去发送的意义。
A novel fair-time division multiple access(F-TDMA)protocol is proposed to support the quality of service(QoS)of realtime applications in moible ad hoc networks.F-TDMA takes the specific timeslot allocation not only to insure the QoS of realtime applications,but also to improve the access performance of ordinary data.Simulation results show that the F-TDMA network has low access delay and high throughput.Expecially for the specific applications,F-TDMA can perform well in the access performance of realtime,and will not make the data useless which is caused by the high access delay.
