Delay Tolerant Network (DTN) aims to provide communication between distant nodes in spite of high end to end delay and frequent disruptions in connectivity. For successful communication between a pair of nodes, a routing protocol is used. The performance of routing protocols for DTN depends upon various factors i.e. bandwidth, residual battery power processing capability and mobility of nodes. Out of these the most prominent factor is mobility. To show the impact of mobility of nodes in simulation various mobility models are used. This paper is an effort to evaluate the performance of routing protocol for DTN using Random Walk (RW) mobility model. Moreover to provide a realistic touch to the simulation environment, cyclic motion among k% of total nodes has been introduced. To carry out the above process, a simulator was designed in MATLAB-7.0. The results show that as the percentage of cyclic nodes increases, the performance of routing protocols decreases significantly.
