水下无线传感网深度调整的混合型路由协议
现有地理路由的水下无线传感器网络数据传输协议经常会出现通信空闲区域,从而导致报文投递率较低、能耗较高。提出一种深度调整的混合型路由协议（GEDAR）,该协议采用地理路由和机会路由进行协作来提升网络数据报文投递率。首先对水下报文投递概率进行估计,然后采用贪婪机会型转发策略来确定用于报文传输的下跳转发节点集合,最后通过深度的拓扑控制来将空闲节点移到新的深度,从而实现通信空闲区域上的通信修复。仿真结果表明,GEDAR协议在报文投递率及每个报文的延时和能耗方面,优于其他基准路由协议。...

| Bibliography: | In underwater wireless sensor networks, the existing data transmission protocols are based on geographic routing and often occur the communication-void regions, and result in the low packet delivery rate and the high energy consumption. In order to solve this problem, a hybrid routing protocol based on the depth adjustment （GEDAR） is proposed. The protocol uses the geographic routing, and the opportunistic routing is used to improve the packet delivery ratio. The protocol first estimates the underwater packet delivery probability, and then uses the greedy opportunistic forwarding to determine the next hop node set for transmitting packets, finally, through depth of topology control the idle nodes are moved to new depth, in order to achieve communication repair at the communication-void regions. Simulation results show that GEDAR outperforms the baseline routing protocols in terms of packet delivery ratio, latency and energy per message. ZHONG Wei-xiong1, HU Yu-peng2 （1.
