【摘要】：由于无线信道的复杂特性,使得无线多跳自组网在实际应用中的可靠、可用性和实时性均难以得到有效保障.对此,提出了面向时延约束下最大化带宽利用率的集中式多跳自组网络协议参数设计策略.基于无线多跳网络集中式通信调度机制,在网络参数、业务参数、协议参数的基础上充分考虑信道参数带来的影响,建立端对端时延模型和带宽利用率模型.数值仿真结果表明,集中式调度机制更适用于节点规模较小的多跳自组网络.基于上述模型增加时延约束确定网络规模,以最大化控制时隙利用率为目标设计协议参数,使网络带宽利用率在满足时延约束的前提下最优.
[Abstract]:Due to the complexity of wireless channel, the reliability of wireless multi-hop ad hoc networks in practical applications is difficult to effectively guarantee the availability and real-time performance of wireless multi-hop ad hoc networks. In this paper, a centralized multi-hop ad hoc network protocol parameter design strategy is proposed to maximize bandwidth utilization under delay constraints. Based on the centralized communication scheduling mechanism of wireless multi-hop network, the end-to-end delay model and bandwidth utilization model are established based on the network parameters, service parameters and protocol parameters. Numerical simulation results show that the centralized scheduling mechanism is more suitable for multi-hop ad hoc networks with smaller nodes. Based on the above-mentioned model, the network size is determined by adding delay constraints, and the protocol parameter is designed to maximize the utilization ratio of control time slot, so that the bandwidth utilization ratio of the network can be optimized under the premise of satisfying the delay constraint.
