The resources that enable cloud logistics have the characteristics of heterogeneity, discrete distribution, dynamics and autonomy. They have an influence on the efficiency of the integration and configuration of the resources. Based on fully considering the classification and the features of the cloud logistics resources, this paper establishes a uniform resource expression model. This model does...
In this paper, we derive application-level reliability metrics of various safety applications with worst-case settings and vehicular environments based on an accurate analytical model in one dimension vehicular communication networks. The reliability related QoS metrics in both the MAC-level and the Application-level including packet reception ratio, T-window reliability, and awareness probability...
The existing methods of Web Service Composition (WSC) seldom consider the initiative and dynamic adaptability of Web Service (WS), which cannot make WS perceive the change of users' requirements in the changeable network environment. The result leads to the failure of Automatic Web Service Composition (AWSC). Meanwhile, the quantity of WS is so large in the existing network environment that the result...
Existing hierarchical routing algorithms for wireless sensor networks mainly focus on distributing energy load among all the nodes. They pay little attention to quality of services (QoS) support in wireless sensor networks. In this paper, we developed a algorithm, QAC (QoS-based adaptive clustering algorithm), which not only concerns energy consumption but also can improve the reliability and the...
Existing hierarchical routing algorithms for wireless sensor networks (WSNs) mainly focus on distributing energy load among all nodes. They pay little attention to quality of services (QoS) support in WSNs. In this paper, we developed an algorithm, local-centralized adaptive clustering algorithm (LAC), which concerns not only energy consumption but also the reliability and the steadiness of the wireless...
