| Abstract(in English) | When mobile hosts share data in ad hoc networks, it is difficult to utilize data on other hosts because connectivity between hosts is not guaranteed due to link disconnections caused by movements of hosts etc. To mitigate this issue, some techniques for distributing replicas of data items to other hosts have been proposed. We have proposed Road-aware Skip Copy (RSC) method, a replica distribution scheme on vehicular ad hoc networks. In the RSC method, replicas are distributed when replica holder is at an intersection. However, replica holders are selected according to the hop count from the original host which generated the data item. Therefore, replicas of data items may not be distributed geographically evenly. Moreover, the increase of the replica distribution traffic caused by distributing repliccis of data items repeatedly by the hosts which received the replica is an issue. In this paper, we propose Road-aware Direction based replica distrubution scheme (RD scheme) for determining the transmission hosts of replica with no duplication at intersections by using information of movement direction etc. of neighboring hosts. |
