Vehicular ad hoc networks (VANETs) are special case of mobile ad hoc networks (MANETs) where non real-time applications are appreciated as compared to real time because of very frequent network partitions caused by high node mobility. Delay tolerant network (DTN) follows the approach of store and forward i.e. message ferrying. In this paper the selection of ferry to forward the data is based on fastest ferry and dynamic speed of ferries. The selection of fastest ferry in variable blocks makes it adaptive to accommodate high speed vehicles which provide maximum packet delivery ratio. The superiority of proposed algorithm is validated by the results obtained by network simulator 2 (ns-2).
