Emergency Connectivity in Ad-Hoc Networks with Selfish Nodes

Inspired by the CONFIDANT protocol [1], we define and study a basic reputation-based protocol in multihop wireless networks with selfish nodes. Its reputation mechanism is implemented through the ability of any node to define a threshold of tolerance for any of its neighbors, and to cut the connection to any of these neighbors that refuse to forward an amount of flow above that threshold. The main question we would like to address is whether …
