Claim:
Method for controlling dissemination of contents in a peer-to-peer mode between mobile peers having wireless communication capacities and comprising a cache memory for storing contents, wherein, each time a peer, having a group of variable values each associated to a content a peer can store into its cache memory and representative of utility that storing of this content represents for the peer and for other peers, said utility being a function of the time required to find said content, accesses to a wireless network or another peer offering access to said contents, in downloading N contents having the N highest variable values into the group of variable values for the peer, N being a number depending on the storage capacity said peer is ready to use into its cache memory to store contents to be downloaded, wherein each peer determines, by using an averaging process, its own group of variable values from reports generated by the peer and reports received from other peers, each report indicating the effect that storing a content in a peer has on the utility of said peer.
