Dissemination asynchrone d'information en mode peer-to-peer dans les reseaux ad-hoc

摘要

This paper presents a model for peer-to-peer, asynchronous data dissemination in ad hoc networks. This model relies on a "collective memory" all stations contribute to implement, according to their capacity. This approach helps tackle station volatility and network fragmentation. Information exchange can be performed asynchronously by stations that are not nessarily active simultaneously in the network. Moreover in a fragmented network a station roaming between network islands can provide its neighbours with information it has gathered while visiting another part of the network.
