碩士 === 國立臺灣科技大學 === 電子工程系 === 104 === Data collection is an important issue in wireless sensor networks. A mobile sink can balance network load; however, mobile sinks introduce challenges related to uncertain movement direction and speed. In this paper, we propose the data collection that takes advantage of a virtual backbone based on a connected dominating set and a rendezvous tree. In the proposed method, sensor nodes work independently to construct a path to the mobile sink without expensive GPS devices. Simulation results show that our algorithm can significantly reduce control packets, decrease data delivery delay, and increase network lifetime over state-of-the-art methods.
