In this paper we propose a routing approach aimed at enhancing the quality of Voice-over-IP (VoIP) transmissions in multipath Wireless Mesh Networks. The proposed approach executes a path switching based on the estimation of the Mean Opinion Score (MOS) for each available path of the mesh network. Performance results conducted through simulations show that the proposed approach, when compared to a...
Opportunistic networks represent a new frontier for networking research as due to node mobility the network might become disconnected. Such intermittent connectivity imposes challenges to protocol design, especially when information access might require the availability of updated information about resources shared by mobile nodes. An opportunistic network can be seen as a peer-to-peer network where...
Support of P2P communities in mobile environments is a challenging task. To this purpose numerous algorithms have been recently proposed to speed up resource search throughout the network. Among these, structured DHT approaches seem very promising since they allow for a successful resource search by keeping complexity low. One of these techniques denoted as Georoy, was recently proposed with the aim...
