Abstract: In order to reduce the energy consumption of wireless sensor networks (WSNs) and control the workload of necessary topology maintenance, the sleep mode in the energy saving strategy is considered. Combining with practice, factors such as environmental interferences, physical damages, signal differences of packets and possible errors in the transmission of data packets are considered. A non-exhaustive M/G/1 repairable queueing model with negative customers, pre-emption, feedback and J optional random vacations is established. Sufficient and necessary condition for the existence of steady state of the system is derived by constructing Markov process with absorption state. Using the supplementary variable method, the expressions of the average number of the data packets and other performance indicators are obtained. Then, using MATLAB software for numerical analysis, the influence of system parameters on the average delay and other performance indicators is analysed. Finally, the social optimal parameters are found by constructing benefit functions. The WSNs model proposed in this paper is also compared with the normal model, and it found that the model with Type J optional sleep has a good energy saving effect.
