In this paper, we investigate the mobile P2P file-sharing problem, and proposed a mobile P2P content distribution architecture. Due to mobile specific influence factors, a hybrid architecture has been employed. We assume that the P2P mobile terminal can publish, index and retrieve resources on the Index Server, and collect the real-time state and cache content resource through Resource Management...
In the wireless heterogeneous environment, to access the Internet ubiquitously, most of the devices are equipped with multiple radio interfaces. Through this way, the multi-homed node can attach to multiple access networks through one or more radio interfaces. However, this brings forth also a problem of how to select a proper interface and access network for an ongoing application on a user's device...
Inter-network mobility is achieved by allowing a mobile node to change its point of attachment to the network while preserving connectivity to its corresponding nodes. Most handover solutions proposed in the literature directly change the whole data flow from one network to another relying on only one network to transfer the entire data stream. These solutions involve a certain amount of quality degradation...
With current Internet Engineering Task Force (IETF) network mobility (NEMO) basic support (NBS) to manage mobility of a mobile network that moves as a whole, all communication to and from mobile network nodes (MNNs) inside the mobile network must go through multiple tunnels between upstream mobile routers and their home agents. This results in the nonoptimized route and increased packet delay between...
Taking advantage of the benefits of modern networking, a growing number of users are exhibiting mobile behavior. As they roam between different network localities, they access the Internet and the Web exploiting both wired and wireless communications and using several heterogeneous devices. Mobile users want to access their subscribed services anywhere, anytime, and want to preserve their currently...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
