基于M/M/1/K排队模型的低功耗无线通信网络TDMA协议延迟评估及仿真

Delay Evaluation and Simulation of TDMA Through M/M/1/K Queue Model in Low-energy Wireless Communication Environment

基于M/M/1/K排队模型对低功耗无线通信网络中的TDMA协议延迟特性进行了评估,利用网络仿真软件QualNet在单跳簇状网络拓扑的条件下对不同接口的TDMA延迟特性进行了相应的仿真,并将仿真结果与评估值进行了对比。仿真表明,该评估方案具有较好的近似性,同时,硬件接口的选择对于减少TDMA延迟时间有着较大的影响。

Evaluate the delay charistiristic of TDMA in low-energy wireless communication environment based on M/ M/1/K queue model, and simulate it by QualNet with two interfaces in single-hop network topology, the simulation data is compared with the evaluation one. It shows that, this evaluation scheme is nearly equal to the simulation outcome. Meantime, the slection of hardware interface lays more influence on the delay of TDMA protocol.
