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)
—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)
The trust levels of cloud services should be evaluated to ensure their reliability. The effectiveness of these evaluations has major effects on user satisfaction, which is increasingly important. However, it is difficult to provide objective evaluations in open and dynamic environments because of the possibilities of malicious evaluations, individual(More)
Routing in wireless sensor networks (WSNs) is an extremely challenging issue due to the features of WSNs. Inspired by the large and single-celled amoeboid organism, slime mold Physarum polycephalum, we establish a novel selecting next hop model (SNH). Based on this model, we present a novel Physarum-based routing scheme (P-bRS) for WSNs to balance routing(More)
In video surveillance, person re-identification consists in recognizing a person or determine whether a given person has already appeared over a large-scale network of cameras. In general, the human appearance obtained in one camera is usually different from the others obtained in other cameras, because of variations in view angle, illumination, body pose,(More)
