The increasing user mobility and more and more powerful mobile devices changed the way services are used today, e.g., by taking the user's location into account. Indeed, service interaction models are also influenced by this development making the ad hoc composition of complementary functionalities possible. Here, particular challenges remain in the field of composing services that are hosted on different...
Security and privacy is a big problem that feazing computer researchers all along. In the pervasive computing, because the traditional methods of user authorization and access control are no longer adapted, the security and privacy becomes much more difficult to ensure. This paper proposes a dynamic trust model based on P2P. In this paper we call the trust model PDTM. The model adopts the technique...
Peer-to-peer constructed on the basis of the distributed hash table don't consider the underlying physical network topology when it build logical overlay, which lead to topology mismatch. In the mobile environment, nodes move randomly, join and leave frequently, which have exacerbated the underlying physical network topology dynamic changes, and further exacerbated mismatch between the logical overlay...
Low efficiency occurs just because physical topology isn't considered when Mobile Peer-to-Peer (MP2P) constructs overlay network; this paper will propose a novel vector location-based algorithm based on Distributed Hash Tables (DHT) algorithm. Using pole coordinates to divide physical network into different zones, constructing new routing protocol based on the location vector information; thus, nodes...
The trend of future communication network is the All-IP network, which brings huge opportunities for mobile P2P network. The distributed computing mode of P2P technology replaces the centralized control mode in traditional telecommunication system, so it makes traditional communication network billing control come across a lot of difficulties. We propose a flow oriented billing model for mobile P2P...
Peer to peer (P2P) file sharing on mobile device has attracted great attention in both academia and industry. Current P2P file sharing applications for mobile users is expensive and still remains a substantial problem for the transmission of the large shared files. In this paper, we discuss the current file sharing possibilities on a 3G network environment. A mobile P2P file sharing solution to facilitate...
