Cooperative sensing data collecting framework by using unmanned aircraft vehicle in wireless sensor network

This paper addresses an efficient data collection scheme based on the cooperative communications by using the UAV for wireless sensor network (WSN). Specifically, we propose a novel system architecture and MAC protocol, which is included how to select the target cooperative sensor node and which sensing data should be retransmitted by using the decided cooperative sensor node. In our evaluations, we reveal the improvement of probability that the sensing data are exactly collected by using the exhaustive Monte Carlo computer simulations. The numerical results demonstrate that our scheme can effectively work when the number of sensor nodes, N, is satisfied with 1, 000 ≤ N ≤ 5, 000 regions, and our scheme can improve by 16.3 %, 46.8 %, 49.8 %, 74.2 % and 92.6 % in case of N = 1,000, 2,000, 3,000, 4,000 and 5,000, respectively.
