| 摘 要： | 无线传感器网络数学建模是网络传输性能定量分析的有效方法之一。该文在分析IEEE802．15．4标准MAC层无信标模式信道竞争机制的基础上，通过节点缓冲队列状态分析、网络节点状态分析和无线信道状态分析，建立了MAC层网络吞吐率、有效吞吐率、节点通信平均延时和信道冲撞概率的数据传输性能数学模型。采用MATLAB软件和QualNet网络仿真软件对所提出MAC层传输性能分析模型和相应性能参数进行仿真测试。仿真结果表明，所提出的数学模型能较为准确的模拟无线传感器网络MAC层通信性能，为网络通信协议数据传输性能定量分析提供了一种建模分析方法。

| Abstract: | Mathematical modeling is an effective quantitative analysis method for performance research of wireless sensor networks. Based on the channel contention mechanism of IEEE802.15.4 standard MAC layer unslotted mode, MAC layer mathematics performance model of throughput, good put, average delay and collision rate are built by analyz- ing the state of node buffer, the state of nodes, and the state of channel. The MAC layer mathematics models and corre- sponding performance are simulated in MATLAB and QualNet respectively. The simulation results indicate that the mathematics models can be used for the real communication quantitative analysis of wireless sensor networks MAC layer communication. |
