Abstract: 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.
