Abstract—These Opportunistic Networks or DTN are the class of networks where the nodes do not have contemporaneous connections, but intermittent connections. In DTN, the main characteristic of packet delivery is large end-toend path latency and a DTN routing protocols has to cope with frequent disconnections. The lifetime of packet would have large effect on the performance of routing protocols in DTN as the delay is large in DTN. In this paper we have investigated the performance of three different routing protocols namely Epidemic, Prophet and RAPID against varying message TTL. For the simulation we have used Opportunistic Network Environment (ONE) Simulator. The performance is analyzed on three metrics: Delivery Probability, Overhead Ratio, and Average Latency. From the results obtained from the simulation it is analyzed that the RAPID routing protocol gives the best performance in the considered scenario and simulation setting.
