网络性能分析是无线传感器网络中的关键问题之一。该文对基于IEEE 802.15.4标准的星形拓扑无线传感器网络性能进行分析。针对无线信道衰落所导致的隐藏终端问题, 分析了传感器节点之间数据冲突的概率, 并在此基础上运用理论分析的方法, 推导了网络的收包率、 平均延迟和平均能耗的这3个性能指标的理论表达式, 并通过仿真实验进行验证。实验结果表明理论结果与仿真结果误差小于5%, 证明了理论表达式的正确性和准确性。
Abstract
Performance analyzes are difficult in wireless sensor networks (WSNs). This study analyzes the performance of a star topology WSN based on the IEEE 802.15.4 standard. The probability of data collision is analyzed for the hidden terminal problem caused by channel fading. Then, the model is used to derive the packet reception rate (PRR), the average delay and the average energy consumption. Simulation results are within 5% of the theoretical results which validate the correctness and accuracy of the theoretical expressions.
