TLDR
A message-driven based algorithm add-on to the existing routing protocols, such as Epidemic Routing and Two-Hop Routing, that enables forwards based on individual message lifetime and delivery requirements, there by improving energy efficiency.Abstract:
Delay-Tolerant Networks (DTNs) are wireless mobile networks having intermittent connectivity among the nodes. DTN nodes mostly operate on limited battery power. Hence, in such networks, there is an immediate need to have energy efficient routing protocol, allowing the network to perform better and live longer for a message with lifetime Et and delivery probability Dp. Most of the work in DTN assumes that all the nodes are co-operative in nature, but in real world, all nodes are not always co-operative, and show some form of selfishness. We propose a message-driven based algorithm add-on to the existing routing protocols (such as Epidemic Routing (ER) and Two-Hop Routing (2HR)), that enables forwards based on individual message lifetime and delivery requirements, there by improving energy efficiency. Further we analytically model the performance of these protocols with energy-efficiency add-on in DTN, with individual node selfishness using Ordinary Differential Equations (ODEs). The results show that the proposed energy-efficient add-on improves the energy efficiency up to 90% for both ER and 2HR protocols. The analysis is validated through extensive simulation.read more

Wu Jiagao,Yiji Zhu,Liu Linfeng +2 more
TL;DR: In this paper, an energy-efficiency based message forwarding method for tolerant networks is proposed, in which the number of copies of messages which meet the conditions and are of small energy consumption is calculated and selected according to the contact rate of network nodes and the probability of message delivery and other information under the conditions that two cells are developed in the tolerant network and social selfishness is shown, wherein the activeness of the nodes and optimal number K of the copies of the message delivered from a source node to a target node are calculated, then the message cannot be forwarded until meeting the target
