Performance analysis of Message Drop Control Source Relay (MDC-SR) in maxprop DTN routing

Abstract

As we know delay tolerant network (DTN) doesn't have an end-to-end path on each node, therefore it can cause an increase in data transmission delay by a huge amount. To overcome that problem, the “Store-Carry-Forward” paradigm is chosen, the paradigm is used to carry the message received by a node to other nodes. In that process, buffer is involved on each node and the process needs a buffer management on each node to increase the delivery probability and decrease the drop on message. On this paper we will be implementing the Message Drop Control Source Relay (MDC-SR) buffer management on MaxProp routing. MaxProp has a low performance using a small buffer. The scenario used in testing the performance of MDC-SR is by using some Upper Bound (UB) in the MDC-SR scheme using the Shortest Path Map Based Movement with random message size.
