Study on a Train- and Bus-based Delay-Tolerant Networks: Scheduled Mobility and Impact on Routing

Scheduled public transports serve as relay nodes that disseminate information from city to village and gather information from village to city. This paper compares the Delay-Tolerant Networks (DTNs) routing protocols to solve the problem of disseminating and gathering information using scheduled public transports that serve as relay nodes. Scenarios were based on a local map with a real environment. The parameters were two scheduled public transports, i.e. buses and trains, with speeds of 0.92 and 2.30 meter/second, 50 meters of transmit range, 10 Mega Bytes buffer size, and some information sizes by the number of differences. The simulation showed that Epidemic, MaxProp, and Spray and Wait (source) routing protocols get more than 87% average of delivery probability and more than 2.6 hours average of latency average.
