Vehicular social networks require real-time communication and are highly dynamic due to vehicle movement. In this article, we present a novel architecture, called VeShare, to support highly dynamic and time-sensitive social behaviors in vehicle networks. VeShare clearly separates a vehicle network into control and data planes. The control plane is managed by the cellular infrastructure. It manages...
Although solutions have been proposed for NAT traversal in UDP based P2P applications, TCP based NAT traversal still remains challenges due to the relatively complicated protocols. In this paper, we propose a Port Correlation Analysis and Prediction (PCAP) algorithm to predict the NAT allocated port number and a novel PCAP based TCP NAT traversal scheme to build successful P2P connections. We evaluate...
Peer-to-peer (P2P) networks have attracted more and more attentions in recent years. The access control model is very important for network environment especially for the dynamic networks such as P2P networks. In this paper, a novel time-sensitive access control was proposed for the P2P networks. Firstly, the time point and time span described by the OCL (object constraint language) was introduced...
In this paper, a novel peer-to-peer (P2P) neighbor selection mechanism was proposed to enhance the efficiency of the file sharing process in P2P networks. In the mechanism, a modified and well-designed neighbor peer selection approach was introduced, which selects the neighbor peer based on the weighted value it holds. The weighted value includes several factors, such as the trust value, the number...
