Adaptive Task Allocation For P2p-Based E-Services Composition, Jun Shen, Shuai Yuan
Adaptive Task Allocation For P2p-Based E-Services Composition, Jun Shen, Shuai Yuan
Faculty of Informatics - Papers (Archive)
To effectively manage the task allocation, especially when handling with numerous different peers’ qualities, is one of the greatest challenges to be faced in order to guarantee the success of P2P-based e-services composition. In this context, various QoS descriptive frameworks and Web services technologies (such as WSDL and BPEL) are being considered as the most affordable solutions to promote the performance of decentralized e-services, through applying strategies like QoS ontologies and related optimization algorithms globally or locally. Nonetheless, most P2P-based service selection and composition approaches applied nowadays lack dynamism and autonomy. In this paper, we first propose an extension of …

Traditional hierarchical intrusion detection systems have a central manager which attracts hackers to attack and might overload when there are too many client requests. To overcome these drawbacks, some researchers suggested to apply Peer-to-Peer approaches in intrusion detection. Most current Peer-to-Peer intrusion detection systems only allow hosts to collect related information from "neighbours" (one hop hosts). The limitation of information sources may lead a system to make inaccurate decisions. In this paper, we propose a Mobile Agent Based Peer-to-Peer Distributed Intrusion Detection Framework. Agents are included in this framework to achieve intrusion detections. In addition, a mobile agent migration strategy …

Many research efforts on application of ontology in network security have been done in the past decade. However, they mostly stop at initial proposal or focus on framework design without detailed representation of intrusion or attack and relevant detection knowledge with ontology. In this paper, the design and implementation of ontology-based knowledge representation for a peer-to-peer multi-agent distributed intrusion detection system (ontology-based MADIDS) are introduced. An example which demonstrates the representation of an attack with ontology and the relevant detection process is also presented. In ontology-Based MADIDS, ontology technique enables peers in the system and agents in one peer to …
