摘要
针对MAC-RSV多址接入协议的侦听中断问题及死锁解决方案中存在的时延抖动问题进行了分析,得出MAC-RSV协议在运行过程中缺乏一种快速的时隙表建立机制,在侦听中断时将导致其接入性能的严重下降.在此基础上对原协议的时隙结构和工作机制进行了调整,提出相应的改进设计方案,使MAC-RSV协议的性能得到了提升.仿真结果对新方案的性能进行了验证.
The Monitor broken problem and delay variation problem when solving deadlock in MAC-RSV Protocol was analyzed, getting that the MAC-RSV protocol is short of a fast slot-table establishing mechanism, which will cause the access performance decline serious- ly. Then the original protocol was changed and modified on the structure and method, the corresponding solving scheme was put forward. Through which the performance of MAC-RSV Protocol was improved remarkably. Finally the performance of the new scheme was verified by the simulation result.
