摘要
水声传感器网络是近年来的新兴应用研究领域,路由机制是其网络协议栈的核心内容,用于在水下建立一条数据传输路径。由于水下应用场景与水声通信环境的特殊性,导致陆上传感器网络的路由机制难以直接应用到水下。文章深入分析了海洋水声传感器网络的应用场景,将其归结为水底的二维平面形式与水下三维立体形式。对于二维平面形式提出了节省能量的路由策略以有效延长网络生存时间;对于水下三维立体形式提出一种不依赖位置信息的路由机制,并针对数据转发中存在的路由空洞设计了有效的路由重构机制。
Recent years have seen a newly emerging trend towards the application of underwater acoustic sensor networks（UASN）. Among the research issues in this promising field, routing mechanism is one of the fundamental problems for constructing the protocol stack and is used for establishing an underwater data transmission path.The routing mechanism of sensor network on land is confronted with difficulties for underwater application due to the unique characteristics of underwater acoustic communication and application scene. In this project, the application scene of UASN is analyzed in an in-depth manner and is summarized as 2D and 3D models. For the2 D network, a new energy-saving routing is proposed to effectively prolong the lifetime; and for the 3D network,a new routing strategy is designed independent from location information. In order to overcome the problem of forwarding void region, this paper presents an effective routing recovery mechanism with delivery guarantee.
