New Adaptive Routing Proposal for DTN

چکیده
In Disruption Tolerant Networks, packet forwarding scheme has a major drawback in terms of network congestion. In order to solve this problem, a New Adaptive Routing Proposal (NARP) has been proposed NARP uses the message forwarding probability scheme in order to increase the delivery ratio and bandwidth utilization. Also, NARP arranges the dropping sequence based on their assigned priority. The priority is determined by the average hop count and average latency. Meanwhile NARP has an ACK list exchange mechanism that is used to purge the redundant messages. Simulation of NARP was carried out and its performance was compared to well known DTN routing protocols: Epidemic Routing, and Spray and Wait Routing. Simulation results show that NARP outperforms them in terms of packet delivery ratio, average latency, and overhead ratio.

Efficient DTN Routing Protocol
This paper presents a novel routing protocol for Disruption Tolerant Networks (DTNs) called Efficient DTN Routing Protocol (EDRP). EDRP smartly integrates the forwarding and buffer management policies into an adaptive protocol that includes a local network parameters estimation mechanism. It dynamically adjusts the delivery probability for messages according to a new metric. Meanwhile, EDRP arr...

We propose a novel DTN routing algorithm, called DQN, specifically designed for quasideterministic networks with an application to satellite constellations. We demonstrate that our proposal efficiently forwards the information over a satellite network derived from the Orbcomm topology while keeping a low replication overhead. We compare our algorithm against other wellknown DTN routing schemes ...

Vehicular Delay Tolerant Networks (DTN) use moving vehicles to sample and relay sensory data for urban areas, making it a promising low-cost solution for the urban sensing and infotainment applications. However, routing in the DTN in real vehicle fleet is a great challenge due to uneven and fluctuant node density caused by vehicle mobility patterns. Moreover, the high vehicle density in urban a...
متن کاملA Novel Multi Copy Routing Scheme for Delay Tolerant Networks
A delay tolerant network (DTN) is a network designed to operate effectively over extreme distances such as those encountered in space communications or on an interplanetary scale. In such an environment, long latency -sometimes measured in minutes, hours or days -is inevitable. However, similar problems can also occur over more modest distances when interference is extreme or the network resour...
