碩士 / 國立臺灣海洋大學 / 資訊工程學系 / 101 / The features of transmissions in underwater sensor networks (UWSNs) include lower transmission rate, longer delay time, and higher power consumption when compared with terrestrial radio transmissions. The negative effects of transmission collisions deteriorate in such environments. Existing UWSN routing protocols do not consider the transmission collision probability differences resulting from different transmission distances. In this paper, we show that collision probability plays an important role in route selection and propose an energy-efficient routing protocol (DRP) considers both distance and residual power issues. Considering the distance-varied collision probability and residual energy, DRP finds a path with high successful transmission rate and residual energy. We confirm that DRP finds the path producing the longest network lifetime through analysis. Simulation results verify that DRP extends network lifetime and increase network throughput when compared with solutions without considering distance-varied collision probability or residual energy.
