摘　　要：针对海洋渔业场景下渔船种类繁杂,具有高移动性且自身资源有限等特性,为提升海上渔船通信可靠性,降低通信能耗,提出了一种基于距离矢量路由(AODV)协议的节能以及可靠性改进方法。首先,分析海上渔船自组网路由协议移动Ad-Hc网络(MANET)的AODV分簇路由的可靠性影响因素,在簇形成阶段和簇头确定时充分考虑海上船只相对速度,以提升通信路由协议的可靠性;然后,考虑多路径衰减能量和簇内渔船数量等实际信息,建立在分簇路由协议下簇头渔船和非簇头渔船的通信能量模型;最后,提出最小方向角和前向通信机制,利用beamforming技术形成方向性的通信选择,以降低海上船只通信耗费能量。理论分析和仿真表明,与传统的AODV路由协议相比,所提出的改进AODV分簇策略数据回传失败率降低40%左右,数据发送30轮次时通信能耗降低25%左右。改进AODV分簇策略的可靠性和节能两个指标在海上渔船通信应用中均大幅提升。For the marine fishery scene,fishing boats are complex,with high mobility and limited resources.In order to improve the reliability and decrease the energy cost of communication,an improved Ad-hoc On-demand Distance Vector(AODV)routing protocol in terms of energy saving and reliability was proposed to make it more applicable for the complicated marine vessel Mobile Ad-hoc Network(MANET).Firstly,based on the analysis of reliability factors affecting AODV clustering routing of MANET,the relative speed of different types of vessels was taken into consideration during cluster formation and cluster head determination phases.Then,the communication energy cost models for cluster and non-cluster boats were established,with considering the multi-path energy loss and the number of boats.Finally,in order to decrease the energy cost of communication between fishing boats,the minimum direction angle and forward mechanism were proposed for data transmission process,in which beamforming technology was adopted to form directional communication options.In comparison with the traditional AODV routing protocol,the data transmission fail rate decreased nearly 40%and the energy cost decreased about 25%at 30 rounds with proposed clustering AODV method.The reliability and energy saving of the proposed AODV clustering strategy are greatly improved in marine fishing communication applications.
