| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The message deliveries based on the store-carry-forward routing schemes, such as Epidemic Routing (ER), are one of useful methods for communicating under DTN environments. However, these methods commonly have their own limitations in reachability of message to destinations and scalability. For example, the propagation delay of message between source and destination nodes generally becomes longer as the distance to the destination increases, and that even the reachability decreases. To overcome these problems, the Virtual Segment (VS) is proposed, which combines an ER method and a wired/wireless high-speed network connecting all base nodes (BN) located on the area. This can improve the reachability and solve the scalability problem.In this paper, we evaluated the effectiveness of the VS method by simulation with the use of actual road network topology after the East Japan Earthquake in 2011. The results showed that the VS method achieved higher successfully delivered ratio and shorter delivered duration than the ER method, even if the traffic volume is much smaller than an usual one. It follows that the VS method is effective even in a challenged network environment such as in a disaster. | |
