This paper proposes the mobile resource discovery algorithm called MRDA, by which mobile phone can communicate based on MANET(Mobile Ad-hoc Network). MRDA is the peer-to-peer structure. It utilizes distributed hash tables (DHTs) to efficiently cache the resource information. Meanwhile, we design the simple datagram structure which can effectively reduce the mobile phone's memory occupancy and decrease...
Service discovery is the premise of service composition. The existing service discovery methods only consider individual service functions and static properties, less considering the inherent dependencies between the composite services. The data dependencies between services reveal the logic correlation between the composite services, but it is of great significance for the service composition and...
P2P storage systems have a lot of attractive advantages, such as self-organizing, scalability, robust and fault-tolerant. Unfortunately, there are some problems in real network conditions, especially, when considering asynchronous wide-area networks, where messages may be delayed indefinitely and nodes may fail. So, failure detector is one of basic components to build a reliable P2P storage systems...
The grid technology enables large-scale sharing and collaboration use of networked resource. Using P2P technology, grid system can have better scalability and dynamic. OGSA provides a framework for integrating P2P technology into grid system. However, grid resource discovery is a key issue for P2P grid. In this paper, a novel model based on P2P technology, is proposed to discovery grid resource efficiently...
Grid computing and peer-to-peer computing are both hot topics at present. The convergence of the two systems is increasingly visible, and OGSA provides a framework for integrating grid and peer to peer. However, grid resource discovery is a key issue for peer-to-peer grid. In contrast with the traditional grid resource discovery algorithm, genetic ant algorithm firstly uses genetic algorithm to find...
Classical approaches to implement Grid resource information service (GRIS) are either centralized or hierarchical. It will result in problems of scalability and single point of failure as the scale of Grid systems rapidly increases. To address scalability and reliability of Grid Resource Information Service, we proposed a distributed resource information service model that extends the information...
Resource discovery is the key requirements in large heterogeneous Grid environments, and an effective and efficient resource discovery mechanism is crucial. However, the complicated and dynamic characteristics of grid resources make sharing and discovering them a challenge. In this paper, a novel model, in which agent and semantic are integrated, is proposed to discovery grid resource efficiently...
