Adaptive data exchange model for opportunistic systems

Epidemic type exchange protocols have often been discussed as a means of disseminating information through a network of nodes. These protocols may be applied to mobile opportunistic ad-hoc networks where the goal is not total dissemination of all information to all nodes but where nodes are interested in attaining specific content for which they have a particular need or desire. In this proposed scenario a shuffle exchange protocol is inefficient, requiring many unnecessary exchanges in order for nodes to receive the content they require. Allowing nodes to self-adapt the amount of content exchanged with each neighbour based on the quality of information received makes it possible for nodes to efficiently receive all content in which they are interested.
