摘要

Satellites in Satellite IP network (SIPN) run alongits orbit and have fixed periods. It is possible to estimate theencounter time between two satellites using their historyencountering information. We introduce a method toestimate the time. Based on the encounter time informationestimated, a new routing method, named Encounter TimeEstimating Routing (ETER), is presented in the paper.ETER firstly estimates the encounter time among satellites.Secondly, it forms a graph, assign values of encounter timeas the weight of edges. Then ETER path algorithm, amodified Dijkstra algorithm, finds the best routing set forpackets. Finally, ETER forward each packet using ETERforwarding algorithm. The simulation result shows thatETER has better performance on packet loss rate andtransferring throughput under all traffic loads; under lowertraffic loads, the average end-to-end delays of ETER is alittle higher than Epidemic routing, but lower than PKR;under higher traffic loads, the delays is lower than PKR andclose to Epidemic routing.
