Abstract
Large quantum of work has already been carried out by researchers in the field of delay tolerant networks (DTN). Most of the past work is related to designing and formulating routing strategies for DTN, managing the buffer using various queuing model, and securing the message bundle. In this work, we have analyzed the removal and accommodation of messages at the node, and observed that there are certain cases in which some messages that are removed from the node to accommodate new messages again arrive at the node through some other node, which in turn initiates the process of removal of the message from the buffer to accommodate this message. This leads to the circular loop of message removal/accommodation which in turn increases the overhead linked with the routing protocol and lowers the delivery probability. So, in this work we have proposed and analyzed the extension to this basic epidemic routing principle to avoid this message accommodation and removal loop. The results that were obtained clearly show that the extension applied to the epidemic routing protocol has a significant impact on the performance of the routing protocol and hence it is to be applied in the working environment.
