Is Internet-Of-Things (IOT) Related to What’s Called "Pervasive Computing"?
It built on earlier ideas, most notably Mark Weiser’s vision for ubiquitous computing described in his 1991 article for Scientific American (The Computer for the 21st Century) in which he described a future world composed of numerous interconnected computers that were designed to “weave themselves into the fabric of everyday life until they are indistinguishable from it” . Elsewhere, in the late 90’s researchers working in Artificial Intelligence (AI) had envisioned the concept of ‘embedded-agents’ whereby AI processes could be made computationally small enough to be integrated into the type of ubiquitous computing and Internet-of-Things devices that Weiser and Ashton had described, opening the possibility for so-called Intelligent Environments or Ambient Intelligence. In these environments the intelligence was distributed to devices making them smart, robust and scalable. The most noteworthy movements were Intelligent Environments, which arose in Europe driven by researchers such as Juan Carlos Augusto of the University of Middlesex (one of the co-founders of the JAISE journal) and Victor Callaghan (one of the co-founders of the International Intelligent Environments Conference series) of the Essex University and ambient intelligence which was originally proposed by the late Eli Zelkha of Palo Alto Ventures in the USA. All these researchers were visionaries, able to imagine a future that had yet to exist, but which they described in such credible terms as to motivate a generation of researchers to work towards bringing these visions to reality, adding numerous innovation of their own as they completed their work. Industry was quick to recognise the potential for these technologies to radically disrupt the market by offering customers services and products that had hitherto not existed, and the consequent challenges of how shape the enormous possibilities into viable products which customers would want and buy.
With CAN-CSM devices are dynamically recombined as computing component by virtual devices recombination technology, and a number of devices to form a virtual computing "system" (Zhang Yunyong, 2003). Lots of technologies are used, such as description of equipment capacity, the ability search, execution and implementation of effective assessment, task distribution, to implement users DCS migration, services, calculation, reflecting the general proper calculation of "computing to adapt human" characteristics in environment for ubiquitous computing of internet things. In addition, the paper also discuss CAN-CSM security issues and future work. Pervasive computing of internet of things is a new cross-research, and it will bring innovation to internet services and it will play a more important role in the next generation of computing technology and in the production and life of human. In the same time, it bringing new challenges and opportunities. After restructuring and building a good "computing area network", the various heterogeneous intelligent computing devices, "integration" of the computer, how to achieve interoperability of components and intercommunication? The key is how to unify description of the device and user needs. The capacity management mechanism is needed for CAN-CSM, and with the ability matching algorithm appropriate device are searched according to user needs (Yu Ying-qun, 2006).
