Local management of credits and debits in mobile ad hoc networks.

Nodes in mobile ad hoc networks often need the communication features of others. However, nodes may not be governed by a single authority and need not share a common goal. Thus, a {\it selfish} node may prefer to save resources for its own communication, rather than to forward packets for other nodes. We propose a framework for collecting information about the forwarding of packets in the network in a decentralized manner. Through reception of acknowlegments, a node can update a local repository, on which the node can rely to judge the behaviour of the other nodes. We define a secure structure for the acknowlegments and rules for updating the local repository. Further, we discuss a solution to achieve a univocal identification of a node in MANET environments.
