水下传感器网络是一种特殊的传感器网络。由于水下通信条件的限制,以水声通信为基础,构建一个简单、高效的水下传感器网络路由协议成为该研究领域当前的重点之一。本文首先阐述了水下传感器网络的几个重要特点和当前实现网络高效通信面临的主要挑战;其次,从水下传感器网络路由协议入手,着重研究了几种不同的利用地理位置信息的路由协议;结合以上两点,提出了一种新的基于位置信息的路由协议——ACR(Annular Compass Routing),并做了仿真研究。
Underwater sensor network is a special kind of sensor network. Due to the limitation of underwater communication conditions, it is one of the most important research fields to construct a simple and efficient routing protocol for underwater sensor networks based on underwater acoustic communication. This paper first describes several important characteristics of underwater sensor networks and the main challenges they are facing to achieve efficient network communication. Secondly, starting with the routing protocols of underwater sensor networks, several different routing protocols that utilize the geographic location information are studied. Combining the above two points, a new routing protocol based on location information (ACR) (Annular Compass Routing) is proposed and simulated.
