Effective routing model for Delay Tolerant Network applications

Delay Tolerant Networking(DTN) is an approach to computer network architecture that seeks to address the technical issues in heterogeneous networks that may lack continuous network connectivity. Due to the lack of continuous communications among mobile nodes, stability becomes major challenge in distributed clustering in Delay Tolerant Mobile Network(DTMN). Based on nodal contact probabilities, a set of functions including synchronization(), in() and out() are devised for cluster formation and gateway selection. The gateway nodes exchange the network information and perform inter-cluster routing or intra clustering routing.
