Social network aware routing for delay tolerant networks

Abstract

In delay tolerant network, the intermittent connectivity makes it difficult to guarantee end to end connectivity and due to long delays makes impossible to provide timely data transfers. The challenges in DTN for providing routing services using store and forward approach over intermittent network connectivity opportunistically using limited buffering capacity of nodes. In this paper, we proposed a routing approach for delay tolerant networks where nodes move in community. Our approach beats the use of buffering on comparing with some of prominent DTN routing algorithms such as Maxprop,Epidemic,Prophet, Spray and wait.The simulation results show the reduction in the use of buffer capacity compared to Epidemic routing in community based social network model while keeping message delivery at desired level. © 2011 Springer-Verlag.
