We deal in this article with the content forwarding problem in delay tolerant networks (DTNs). We first formulate the content delivery interaction as a noncooperative satisfaction game. On one hand, the source node seeks to ensure a delivery probability above some given threshold. On the other hand, the relay nodes seek to maximize their own payoffs. The source node offers a reward (virtual coins)...
The mobile nodes in delay tolerant networks communicate with each other using a store-carry and forward mechanism even though there is no permanent link between the source and the destination. This mechanism requires cooperation between nodes. However, because of limited resources such as storage and energy, most of the nodes act in a non-cooperative way. In this paper, an incentive mechanism is proposed...
This paper introduces a new incentive mechanism for content caching in Delay Tolerant Network (DTN) aiming to improve the performance under relays energy cost. We model this distributed network problem as non-cooperative game, we focus on the source-relay interaction to investigate how far data transmission could be sustained. For instance, due to a limited capacity storage and battery lifetime the...
This paper introduces a reward-based incentive mechanism for file caching in Delay Tolerant Networks (DTNs). In DTNs, nodes use relay's store-carry and forward paradigm to transmit data till final destinations under intermittent connectivity. However, the relays are not always available to assist data transmission due to limited energy or low storage capacity. Our proposal is based on a reward mechanism...
