Hydraulic-Pressure-Based Anycast Routing for Underwater Sensor Networks*
摘要
Abstract
Due to the node mobility and limited resources(bandwidth and energy)of the mobile node of Underwater sensor networks,designing an efficient anycast routing protocol from a mobile sensor to any sonobuoy at sea level is key issue. Therefore Hydraulic-pressure-based anycast routing(HPAR)is proposed in this paper. HPAR makes rout?ing decisions based on hydraulic-pressure,and optimal next forwarding node is selected by packet advancement. Whenever a sensor node needs to send a packet,HPAR uses the packet advancement(ADV)to determine the neigh?bors candidate set,then uses normalized advance(NADV)to measure the"goodness"of each nodes in neighbors can?didate set,and ordered by NADV metric,finally form the ordered neighbors candidate set. NADV corresponds the optimal trade-off between the proximity and link cost to determine the priorities of the candidate nodes. In addition, the ordered neighbors candidate set is divided into several clusters,so that each node in clusters must hear each oth?er. HPAR computes the Expected Packet Advanced(EPA),and the cluster with the highest EPA is selected to be the next-hop forwarder cluster. Finally,the redundant packet is suppressed by timer,and parameter of timer is opti?mal. Simulation results show that HPAR protocol has a good performance in terms of average numbers of redun?dant packets and packet delivery ratio.关键词
