System and method for sharing distributed capacity in an ad-hoc network

A system is provided for sharing capacity in a communications network comprising a set of nodes sharing common resources, where the nodes are able to be connected by pairs via communications links. Each node is capable of locally holding at least one set of triplets (k, l, Nkl) which associates, with each link (k, l), an expiration time Nkl representing the date until which the associated link may be considered as unused. The nodes are furthermore configured for periodically exchanging, according to a predefined period p, control messages over a set of links, each control message sent over a given link by a node comprising the sets of triplets held locally by the node and which correspond to the links that are in conflict with said given link.
