| Abstract: | Data Transfer Rate-based Routing(DTRR) is proposed for Delay-Tolerant Networks(DTNs). Each message is divided into several message blocks. When the source node meets the appropriate forwarding node, it transmits the message block, otherwise it stores the message block in the cache. At the same time, the DTRR combines the contact frequency, the duration of the contact and the available space of the cache area to deduce the message transmission rate of the link. The next hop forwarding node is selected according to the message transmission rate. Simulation results show that the proposed DTRR has better performance in message transmission rate than similar Spray-and-Wait Routing(SWR). |
