DMEK: Improving Profile Matching in Opportunistic Collaborations.

As the number of mobile devices grow, also grows the amount of data exchanged. This ever growing amount of data may overload Internet Service Providers. A possible solution to this problem is to use the mobile devices wireless network capabilities to exchange data by creating mobile P2P networks. These networks should opportunistically collaborate to exchange information to other devices in their proximity, only requiring users to specify their interests. This paper presents DMEK, (Decision Mobile Exchange of Knowledge) a solution where mobile devices disseminate knowledge among their users, opportunistically, using a decision mechanism based on profile matching. Experiments show DMEK feasibility and performance.
