Research on Underwater Wireless Acoustic Communication Routing Protocol

Due to the limitation of communication range sensor nodes, underwater nodes must transmit data water surface through routing mechanism. Therefore, design algorithm is related performance network, and research necessary. However, are vulnerable ocean turbulence biological factors. The environment dynamic complex, which greatly affects acoustic channel, making improvement protocol a challenge. These factors lead problems in such as empty packet delivery rate, energy consumption, delay other problems, complex seawater environment, network will be further reduced. This paper introduces some main algorithms, hollow node awareness algorithm, layer-based protocol; Opportunistic algorithm; Double-hop protocol, etc. algorithms can solve problems. Simulation shows that they have certain advantages delay, lifetime,
