摘　　要：针对能量受限无线传输的可靠性问题,提出一种计算线性传感器网络可靠性的概率表达式。建立包含传输模型、能量模型、链路模型、业务模型的系统模型。推导源节点在能耗基础上的可靠性表达式,考虑链路的情况推导出链路的正常工作概率表达式,综合考虑节点和链路的情况推导出整体传输的可靠性表达式。仿真结果证明,该可靠性表达式能够准确地评估无线传输的可靠性能。For the reliability issues of the wireless transmission which energy is limited, this paper puts forward the probability expression to calculation the reliability of linear sensor network. It establishes a system model, which includes transfer model, energy model, link model and service model. By taking into account the energy consumption of sensors, it derives the reliability expression of the source node. Considering the condition of link, the normal operation probability expression of link is derived. The reliability expression of the transmission is obtained by comprehensive consideration of the nodes and link situations. Simulation results show that the reliability expression can provide sufficient precision for evaluating the reliable performance of wireless transmission.
