Software Defined Networking (SDN) is an emerging networking paradigm which intends to merge networks into the age of the cloud, providing fine-grained control, simplified configurations, unprecedented flexibility and seamless scalability. However, due to the large set of unresolved challenges as well as the deployment cost, network evolution to fully SDN systems will take a long time. In fact, SDN...
In this paper, we analyze a cooperative medium access scheme in a wireless relaying network using Bayesian games, where the participating nodes are peers subject to the half-duplex constraint and they choose to cooperate or not cooperate based on its expected utility. We first set up a one-stage game and derive the ex-post utility. A two-stage game with incomplete information is further formulated...
The resource distribution in P2P network has an obvious scale free character. Using this inherent character to design resource search strategy is great significant for improving searching efficiency and reducing the costs. We analyze the scale free distribution character in P2P network, and propose a reliable random walk search algorithm to achieve high and reliable search efficiency through forwarding...
Huge amounts of data are available in large-scale networks of autonomous data sources dispersed over a wide area. Data mining is an essential technology for obtaining hidden and valuable knowledge from these networked data sources. In this paper, we investigate clustering, one of the most important data mining tasks, in one of such networked computing environments, i.e., Peer-to-Peer (P2P) network...
Load balance in P2P storage system will affect availability greatly. Two aspects should be considered in keeping balance: balance in peer space and balance in data replica among peers. This paper focuses on achieving balance in peer space. Peers are categorized by periodicity of availability, and long term peers are organized into virtual balanced binary tree which is improved from P-Grid. Character...
Secure joining process has become the most challenging problem in P2P system. This paper presents a joining process with security in P-Grid system including authentication of entry peer and new peer. The core idea to ensure security authentication is to use multiple consultant peers and a quorum-based method to make a decision. From preliminary analysis of the process, high successful probability...
Peer-to-peer (P2P) technology provides an efficient way for resource distribution, and sharing. While most current P2P systems only support queries over a single attribute which limits the popularity of the P2P technology. Full-blown P2P applications require the efficient resource searching supporting multi-dimensional attributes. In this paper, we propose flabellate overlay network (FAN), a scalable...
Real-time collaborative editing systems allow a group of users to view and edit the same document at the same time from geographically dispersed sites connected by communication networks. Consistency maintenance in concurrent access of shared objects is one of the key issues in designing these types of systems. This paper proposes a P2P-based locking schema for concurrency control in internet-based...
