【摘要】：水下传感器网络(UWSN)在海洋河流的资源探索、海洋环境监控、地震海啸自然灾害预防、航海导航、国防安全等众多方面有非常重要的意义。水下传感器网络具有很多独特的性质,如带宽受限,能量有限且发送信息时损耗严重,较长时延,高误码率等,已存在的很多网络技术和协议是以陆地传感器网络为对象发展和研究的,由于水下环境和陆地相比差异较大,这些技术方法和协议措施不适用于水声网络。为了探索适合水下网络环境特点的协议和技术,需要继续进一步研究。本文对水下传感器网络中基于地理位置信息的路由协议及节能算法进行了研究。介绍了典型的水声传感器网络路由协议,详细阐述了水声网络基于地理位置信息的路由协议;深入研究了水声网络中现有的节能技术,将无线传感器网络的节能算法分为四类,并对每一类算法进行阐述,由此启发本文设计出水下传感器网络基于地理位置路由的节能算法,在节省能量开销的同时,有效的均衡整个网络能量消耗。为解决水下传感器网络中节点能量有限,能量消耗不均匀,产生网络空洞,进而导致网络生存时间短的问题,本文在研究了水下三维的地理路由协议及能量路由协议后,提出了一种基于经典的矢量转发路由协议(VBF)的能量路由协议——基于矢量转发的能量路由协议(E-VBF)。该协议较好融合了节点的地理位置信息及能量信息,与原协议相比节省网络能耗,平衡整个网络的能量开销,使得网络生存时间延长。文章通过仿真实验验证了E-VBF的实际性能,证明该协议达到了所希望的节省能量和均衡网络能耗的效果。同时,对E-VBF协议的参数进行深入理论分析和仿真检验,证明了本文中协议参数的理论分析,明确了参数的选择对于协议性能的影响。
[Abstract]:Underwater sensor network (UWSN) is of great significance in the exploration of ocean resources, monitoring of marine environment, prevention of earthquake and tsunami natural disasters, navigation navigation, national defense security and so on. Underwater sensor networks have many unique properties. Many existing network technologies and protocols have been developed and studied based on terrestrial sensor networks, such as limited bandwidth, limited energy, serious loss when sending information, long delay, high bit error rate and so on. These technical methods and protocol measures are not suitable for underwater acoustic networks because of the large differences between underwater environment and land. In order to explore protocols and technologies suitable for underwater network environment, In this paper, the routing protocol and energy saving algorithm based on geographical location information in underwater sensor networks are studied, and the typical routing protocols for underwater acoustic sensor networks are introduced. The routing protocol of underwater acoustic network based on geographical location information is described in detail, the existing energy-saving technology in underwater acoustic network is deeply studied, the energy-saving algorithm of wireless sensor network is divided into four categories, and each kind of algorithm is described. Therefore, an energy saving algorithm based on geographical routing for underwater sensor networks is designed in this paper, which can effectively balance the energy consumption of the whole network while saving energy. In order to solve the problem of the limited energy of nodes in underwater sensor networks, The energy consumption is uneven, resulting in network void, which leads to the short lifetime of the network. In this paper, after studying the three dimensional underwater geo-routing protocol and energy routing protocol, This paper presents an energy routing protocol based on the classical vector forwarding protocol (VBF), the energy routing protocol based on vector forwarding (E-VBFN), which combines the geographic location information and energy information of nodes, and saves network energy consumption compared with the original protocol. The energy cost of the whole network is balanced to prolong the network lifetime. The actual performance of E-VBF is verified by simulation experiments. It is proved that the proposed protocol achieves the desired effect of saving energy and balancing network energy consumption. The theoretical analysis and simulation of the parameters of E-VBF protocol are carried out, and the theoretical analysis of the protocol parameters in this paper is proved, and the influence of the choice of parameters on the performance of the protocol is clarified.
