Delay Tolerant Networking over the Metropolitan Public Transportation

الملخص EN

We discuss MDTN: a delay tolerant application platform built on top of the Public Transportation System (PTS) and able to provide service access while exploiting opportunistic connectivity.

Our solution adopts a carrier-based approach where buses act as data collectors for user requests requiring Internet access.

Simulations based on real maps and PTS routes with state-of-the-art routing protocols demonstrate that MDTN represents a viable solution for elastic nonreal-time service delivery.

Nevertheless, performance indexes of the considered routing policies show that there is no golden rule for optimal performance and a tailored routing strategy is required for each specific case.
