摘要: 在水下无线传感器网络中,传感节点带宽和能量受限阻碍了从移动节点至声纳浮标的数据传输。为此,提出新的水下无线传感器网络的机会路由协议。引入深度阈值提高吞吐量,减少跳数,利用深度阈值构建候选转发集,计算候选转发集内节点的路由指标,依据路由指标设置优先级,根据优先级设置定时器,并进行抑制冗余数据包数。实验结果表明,与基于压力感测协议相比,该协议能提高网络吞吐量,并降低能耗。

Abstract: In Underwater Wireless Sensor Network(UWSN),limited resources (bandwidth and energy) of the sensor nodes hinder the data transmitting from a mobile sensor to any sonobuoy.Therefore,a novel opportunistic routing for UWSN is proposed in this paper.It introduces depth threshold to select the reliable and lower depth forwarder node which improves goodput and reduces number of hops.Whenever a sensor node needs to send a packet,it uses the depth to determine the candidate forwarding set,then computes the path metric of each node in candidate forwarding set,which can reflect the reliability of link,and order by path metric.Finally,the redundant packet is suppressed by timer.Simulation results show that this protocol has better energy utilization and network goodput compared with pressure based sensing protocol.

Key words: Underwater Wireless Sensor Network(UWSN), opportunity routing, depth, routing indicator, reliable link
