D TN中基于地理位置信息的备用副本转发算法
Location aided routing with alternative copy in DTN
摘要
Abstract
In allusion to the characteristics of lack of persistent end to end connections,high delays and restricted node re-sources in DTN,in order to improve the delivery ratio and decrease the network overheads,this paper proposed a location sha-ring model based broadcast and a routing algorithm based on location information with alternative copies.The algorithm com-bined DTN with GPRS to provide reliable node locations and speed vectors for the selection of forwarding nodes under the con-dition of no GPRS base stations;when failing in forwarding the message copy,it selected another node to forward the alterna-tive copy,while delaying the alternative copy when success.The simulation results show that the proposed algorithm performs better in terms to the delivery ratio,the average end-to-end delays and the network overheads,which is significative to use in the VANET.关键词
