Content discovery and caching in mobile networks

We consider content discovery in wireless networks with infrastructure, where mobile nodes store, advertise and consume contents while Broker entities running on infrastructure devices let demand and offer meet. We refer to this paradigm as match-making, highlighting its features within the confines of the standard publish-and-subscribe paradigm. We combine such content discovery scheme with an efficient caching strategy that ensures a high hit probability. Furthermore, through a reputation-based mechanism, we counter the nodes that deceive the Broker into believing they cached a content whereas they did not. The performance of our match-making scheme is derived through ns-3 emulation/simulation.
