Performance analysis of dLife routing in a delay tolerant networks

Delay Tolerant Network (DTN) is a wireless network that connected in an intermittently manner and have dynamic topology. In DTN to design protocol routing is a big challenge due to there is no end-to-end path. To overcome this challenge there is protocol routing dLife. dLife is a protocol routing in DTN that use two utility function to determine forwarding decision, namely TECD (Time-Evolving Contact Duration) and TECD importance. In this paper we study the impact of buffer size and message size on the performance of dLife routing. For the simulation we used Opportunistic Network Environment (ONE) Simulator. The performance that is analyzed are Overhead Ratio, Delivery Probability and Average Latency. Based on simulation result, buffer size and message size affect to the performance of dLife routing.
