基于节点密度自适应的低时延水下网络路由协议研究
Low-latency underwater network routing protocol based on node density adaptation
摘要
Abstract
In view of the low packet delivery rate and large average delay in underwater wireless sensor networks,this paper proposes a low-latency underwater routing protocol DALRP based on node density adaptation.In this protocol,the forwarding area is set according to the direction of the destination node,and the forwarding angle is determined based on the density of network nodes,and the angle selection at each density is optimized by experiments.The probabilistic forwarding algorithm is used to divide the forwarding area,so that the forwarding nodes close to the destination node have a higher forwarding probability.Simulation optimizes distance thresholds,energy thresholds,and distance progressions to determine forwarding factors and waiting time.By these mechanisms,DALRP can reduce end-to-end data transmission latency while balancing network performance.By changing the number of nodes in the network and the maximum movement speed of nodes,the packet delivery rate and average delay are compared,respectively.The simulations show that the DALRP is better than the protocols HHVBF,GTRP and LDRP in terms of packet delivery rate and delay performance.To sum up,it can effectively improve the packet delivery rate.关键词
