To satisfy the requirements of reliable Web services, the mechanism of adaptive failure detection for Web services in the dynamical network environment is studied. A framework of hierarchical failure detection is presented firstly, then an algorithm based on freshpoint and load awareness is presented. It considers the factors including the frequency of message delivering and the message loss probability...
To meet the requirements of Wireless Sensor Networks (WSNs), a QoS guarantee mechanism based on service-oriented middleware is presented. Focus on the problem of quality of service (QoS) evaluation, a QoS evaluation algorithm based on a model of multi-dimension cloud is proposed. It evaluates quantitatively the tasks, which can make the network be scheduled properly by middleware according to the...
