基于分布式时隙调度协议的战术互联网媒体访问控制技术

Tactical Internet Media Access Control Technique Based on Distributed Time-Slot Scheduling Protocol (DTSP)

在分析现有移动无线网络TDMA时隙调度问题的基础上,根据战术互联网骨干网拓扑与业务需求,结合跳频电台的特点,提出了一种新的动态分布式TDMA时隙调度协议(DTSP),能够适应不同业务需求,支持单播、广播和组播。DTSP协议以无冲突的预留提高系统吞吐量,以渐增方式适应动态拓扑变化,动态调整的开销较小。最后,以DTSP时隙单播预留协议为例,进行了详细分析和复杂度计算。

Based on reviewing of current time - slot scheduling solution in TDMA of Tactical Interact （TI）, according to the requirement of backbone topology and traffic, speciality of frequency hopping, this paper presents a new dynamic Distributed Time- Slot sch6duling Protocol （DTSP） in media access control （MAC） layer of TDMA network..The DTSP supports broadcast schedule, time -slot reservation and cont- ention, using hybrid mechanism combining reservation and contention to enhance network throughput. The DTSP addresses mobility issue can make cost decrease in an incremental way. Finally, it analyses the unicast DTSP and algorithm complexity.
