A Pervasive Computing Model of Internet of Things based on Computing Area Network

Pervasive computing is considered as a new computing model providing computing and services, representing developing direction of the coming generation of information.  The emergence of The Network of Things makes changes to the environment of pervasive computing， and the internet of users expanded the spaces and information. It also sets an even higher demand on pervasive computing and upgrade support service and promotes pervasive computing becoming the basic computing model of internet of things.  Basing on the new hierarchy computing model of pervasive computing, a new control system model of computing area network (called CAN-CSM) is presented in this paper, regarding as core implement and virtual computing nodes.  The internet of things is composition of a large number of CAN. The main function of CAN is reconstruction of virtual equipments dynamically, and it can describes ability, execute estimation, delivering work, providing Data+Code+Status service migrations.   In the context of internet of things, things part of "computing area network" can be seen as an abstract "reconfigurable" computer, which is a great innovative way.
