Delay tolerant network (DTN) has been utilized for intermittent network, where no. of hosts are movable, there is no fixed topology and connection is opportunistic. It is challenging to transmit data in such opportunistic environment. DTN is also applied in Vehicular nodes known as Vehicular delay tolerant network (VDTN). The message transmission in VDTN using different routing protocols needs to be improved as VDTN suffers from the high speed of vehicles, short contact time and unstable topology and very high delay for message passing. The objective of this paper is to do comparative analysis of five different protocols of VDTN with variance of various parameters and suggest one protocol for optimum performance concentrating Overhead Ratio. Overhead Ratio is compared on parameters - variation in no. of nodes, buffer size and transmission data rate. Rating system is used to analyze comparative study. All protocols are implemented using The ONE simulator.
