| 摘 要： | 基于分布式无线网络,提出可以支持话音、数据同传的动态资源预留接入控制协议(DDFRMA),并建立数学模型,分析话音分组传输时节点数与丢包率的关系。通过仿真得出不同条件下所能允许的最大通话数目,并与CSMA/CA接入机制进行比较。仿真结果表明,该协议可以有效支持分布式网络中的话音传输,提高接入机制的话音容量。

| Abstract: | Based on the distributed wireless networks, this paper proposes a new MAC mechanism protocol——Distributed Dynamic Frame Reservation Multiple Access(DDFRMA) which supports voice and data transmitting together. The Markov model is built to analyze the relationships between nodes and the voice packets dropping probability. Simulation results show that the protocol can support voice transmitting of distributed networks, improves the voice capacity of access mechanism, compared with the CSMA/CA mechanism. |
