In Mobile Peer-to-Peer networks (MP2P), the network state information is difficult to measure accurately, and application requirement on quality of service (QoS) and trust is also hard to exactly express. Therefore, trust QoS routing scheme should be based on the fuzzy information. In this paper, we propose a trust QoS routing scheme based on interval matching. It applies the interval form to denote...
A mobile ad hoc network (MANET) is a self-configurable infrastructure less wireless network of mobile devices. The devices or nodes can move randomly in the network which results in frequent change in the topology. This paper proposes trust establishment in MANET. Since the nodes are constantly entering and leaving the network, security in the network will be less. So in order to establish security...
This paper presents the various mechanisms for virtual machine image distribution within a large batch farm and between sites that offer cloud computing services. The work is presented within the context of the Large Hadron Collider Computing Grid (LCG), it has two main goals. First it aims at presenting the CERN specific mechanisms that have been put in place to test the pre-staging of virtual machine...
The decentralized structure makes P2P network an effective model for file sharing. However, how to avoid the ??free-rider?? of file sharing in P2P network is a crucial problem. With the combination of fairness thought, an incentive strategy based on peer trust degree has been proposed. Each peer in this model is a credit entity. Each node submits feedback about queried node after transaction, and...
In peer-to-peer content delivery systems, such as BitTorrent, there may exist nodes that are non-cooperative and do not contribute their upload bandwidth to the system while still downloading content from others. The current widely used countermeasures against this freeriding behavior have been shown to be ineffective. In this paper, we address the problem by leveraging the trust latent in the social...
