摘　　要：协作路由能够提高水域环境中数据包传递率,为此提出基于深度和位置的协作路由(depth and location-based cooperative routing,DLCR)。结合传感节点深度和位置信息,选择目的节点,使所选择的目的节点更靠近于水表面,减少数据包的传输受信道特性的影响;源节点接收选择一个转发节点和目的节点,当接收了数据包,转发节点就向目的节点转发。仿真数据表明,与能效的最优转发节点路由(energy-efficient optimal relay selection,EEORS)相比,提出的DLCR路由的数据包传递率得到了有效的提升。Collaborative routing improves packet delivery in underwater environment.Therefore,a depth and location-based cooperative routing(DLCR)was proposed.Location and depth of the sensor nodes were combined to select the destination nodes,which resulted in selection of the destination nodes closest to the water surface.As a result,data packets were less affec-ted by the channel properties.In addition,a source node chose a relay node and a destination node.Data packets were sent to the destination node by the relay node as soon as the relay node received them.Compared with energy-efficient optimal relay selection(EEORS)routing,simulation results show that DLCR protocol has good performances in terms of packet delivery ratio.
