Information Dissemination using Epidemic Routing with Delayed Feedback

Information dissemination is one of the most important aspects of routing mechanisms for network management. We study in this paper the problem of disseminating an information by a source trough all the nodes of a network. We consider an epidemic routing protocol in an Ad hoc network with a delayed feedback to the source. Indeed, the source controls the dissemination of the information in the network by sending an anti-packet, like a vaccine. We show that there exists a sufficient condition for stability of the information dissemination in the network depending on the spreading of information in the network and the delay of the feedback to the source.
