Internet of Things (IoT) is a heterogeneous, mixed and uncertain ubiquitous network, the application prospect of which is extensive in the field of modern intelligent service. Having done a deep investigation on the discrepancies between service offering and application requirement, we believed that current IoT lacks enough intelligence and cannot achieve(More)
In order to deal with the situation that current Internet cannot meet application requirements, we analyze the three features—pervasiveness, heterogeneity and intelligence that the future Internet possesses firstly. Secondly, we syncretize the technologies of cognition, cooperation, cross-layer, virtualization and cloud computing, and present a new(More)
The rising popularity of smartphones and vehicles equipped with onboard sensors sheds lights on building a city-scale sensing system for urban surveillance. This paper proposes a novel metric, urban resolution, to measure the quality of urban sensing. Urban resolution describes how sensitivity the urban sensing system could achieve for environment(More)
Recent years, more and more enterprises migrate their applications to the cloud for cost saving. During the application migration, an application usually needs to be re-designed from a workflow to an execution plan on a cloud platform. Based on the execution plan, many scheduling optimization approaches have been proposed to improve the performance of the(More)
Cognitive Internet of Things (CIoT) mainly consists of a group of autonomous nodes (ANs) which are commonly combined into domains and should have the intelligence to perceive, analyze, decide and act. Cooperation has shown to be a good technique for collective behavior of ANs that locally interact with each other in distributed environments. In this paper,(More)
The Internet has evolved from an academic network to a broad commercial platform and become an integral and indispensable part of our daily life, economic operation, and society over forty years. However, many technical and non-technical challenges have emerged during this process. In order to address these challenges, we analyze the three(More)
