The paper entitled “A Protocol Design for Mobility Assisted Delay / Disruption Tolerant Network Nodes” mainly intends in designing a disruption tolerant network useful for challenged internet areas lacking “always-on” setup, fewer expectations of end-to-end connection and node resources. Disruption Tolerant Networking (DTN) is a networking area which addresses challenges in disconnected, disrupted networks without end-to-end connection. Today’s internet operated using highly successful architecture and supporting protocols (protocols in TCP/IP model) performs poorly in environments characterized by very long delay paths and frequent network partitions. These problems make end nodes having severe power or memory constraints perform poor. Many DTN networks use their own specialized protocols like Licklider Transmission Protocol (LTP), Bundle Protocol (BP) etc. In order to achieve interoperability between such networks, an overlay architecture is designed above the transport layers of the networks it interconnects provides important services such as in-network data storage and retransmission capability, interoperable naming, coarse-grained class of services and authenticated forwarding. A network with three node test setup is created which will demonstrate the working of delay/disruption tolerant network for asymmetric data rates, high error rates, long and variable delays and intermittent connectivity.
