| Abstract(in English) | An epidemic broadcast, in which an infected node repeatedly forwards a copy of the message to encounter nodes, realizes one-to-many communication in DTNs(Delay/Disruption-Tolerant Networks). In an epidemic broadcast, the key is to control the number of message fowardings among nodes while maintaining a short message delivery time in the network. In this paper, we present a novel idea for improving the performance of an epidemic broadcast-when an infected node encouters a (possibly) sucepbible node, the infected node intentionally delays its message forwarding since delaying the mes- sage forwarding may increase the chance of simultaneous transmission to multiple sucepbible nodes. Based on the idea, we propose HCD-BCAST(History-based Contact-Duration aware BroadCAST), which significantly reduces the number of message forwardings. In HCD-BCAST, every node autonomously determines the delay time of message forwarding based on the measurement of contact-duration distribution. Through simulation, we show that HCD-BCAST achieves approximately 30% reduction in the number of message forwardings compared with HSA-BCAST(H..S..A...B...CAST). |
