Cluster Head Bundle Delivery Protocol for Delay Tolerant Networks

In challenging network scenarios like battlefield and disaster recovery scenarios, nodes suffer from frequent network partitions and intermittent connectivity. In these scenarios instantaneous end-to-end path between the sender and receiver will not exist due to link breakdown, less battery or mobility of nodes. To address these challenges in challenged networks, DTN architecture with store and forward mechanism is already proposed. But, the existing routing protocols proposed for DTN fails to address the bundle forwarding when a node is out its own network. Therefore the delay in message delivery increases further. Also it lacks for centralized control and scalability problems. Here we propose, an enhanced bundle delivery routing protocol with cluster head for DTN to address the above issues.
