Nowadays, a new paradigm is emerging: the challenging integration of Peer-to-Peer into mobile Ad hoc networks (MANETs). In this context, this paper proposes a new distributed lookup protocol for mobile P2P networks. Its main objective is to reduce the overhead traffic and the lookup delay. Simulation results indicate that the proposed scheme has an improved performance in comparison with the popularly...
Mobile Ad hoc Networks (MANETs) are formed by collection of, potentially mobile, portable devices without established infrastructure. In such networks, connectivity is established through IP addresses and dynamic routing. MANETs are highly dynamic with frequent nodes joining and departure. Due to this node dynamicity, the node's IP address changes frequently. Therefore, to enable and run common user...
In modern age portable handheld devices are changing the norms of traditional communication structure by introducing mobility and dynamism. In general when a mobile client wants services from a database server, the client has to continuously report its location to the server. With untrustworthy servers, location-based services (LBS) may pose a major privacy threat on its users. In this paper, we propose...
In this paper, we present an algorithm for an effective flooding procedure with reduced cost in a DHT based P2P network. We describe techniques of flooding and replication that exploit structural constraints to achieve low overhead and higher reliability. These techniques can help to support complex queries in mobile distributed environments with better performance.
