Wireless sensor networks typically consist of failure-prone sensor nodes and more reliable sink nodes. To prevent data loss, sensor nodes must regularly transfer the data stored in their local storage to sink nodes. Therefore, setting up an appropriate data transfer rate/interval between sensor and sink nodes is important to minimize data loss in failure-prone wireless sensor networks. This paper presents a method to optimize the data transfer interval based on a Markov model. Although the Markov model directly implies the assumption of exponentially distributed failures' inter-arrival times, using extensive simulations, we showed that the optimal data transfer interval derived by this model still performs exceptionally well under other failure distributions with less than 7.3% difference in terms of period of data loss compared to the true optimal data transfer interval. We also discuss how to integrate the proposed method into the widely used communication protocol in WSN, TDMA, and show that it can improve data collection time and energy efficiency.
