Scheduling and Dropping Policies in Vehicular Delay Tolerant Network
Vehicular Delay-Tolerant Networking (VDTN) is projected as a new alternative of a Delay Tolerant Network (DTN), designed for vehicular networks. The characteristic of VDTN are intermittent connectivity, high node mobility and shorted contact duration. Due to this messages are sent with more amount of delay and still so many of the messages are dropped. As VDTN networks are resource controlled, i.e. in terms of communication bandwidth and storage space, main challenge is to have scheduling and dropping policies that can get better overall performance of the network.
