دانلود Enabling IoT automation using local clouds

Abstract

Various  forms  of  cloud  computing  principles  and technologies  are  becoming  important  recently.  This  paper  ad-dresses cloud computing for automation and control applications. It’s argued that the open Internet cloud idea has such limitations that  its  not  appropriate  for  automation. Since  automation  is  physically  and  geographically  local,  it  is inevitable  to  introduce  the  concept  of  local  automation  clouds. It’s  here  proposed  that  local  automation  clouds  should  be  self contained  an  be  able  to  execute  the  intended  automation  functionalities without any external resources. Thus providing a fence at the rim of the local cloud preventing any inbound or outbound communication.   Such   a   local   cloud   provides   possibilities   to address key requirements of both todays and future automation solutions. Adding mechanisms for secure inter-cloud administration  and  data  tranfere  enables  local  automation  cloud  to  meet IoT automation system requirements as: 1) Interoperability of a wide range of IoT and legacy devices 2) Automation requirement on  latency  guarantee/prediction  for  communication  and  control computations. 3) Scalability of automation systems enabling very large  integrated  automation  systems  4)  Security  and  related safety  of  automation  systems  5)  Ease  of  application  engineering6)  Multi  stakeholder  integration  and  operations  agility. How these requirements can be met in such a local automation cloud is discussed with references to proposed solutions. The local automation cloud concept is further verified for a compartment climate control application. The control application included an IoT  controller,  four  IoT  sensors  and  actuators,  and  a  physical layer communication gateway. The gateway acted as host for local cloud  core  functionalities.  The  climate  control  application  has successfully been implemented using the open source Arrowhead Framework  and  its  supports  for  design  and  implementation  of self  contained  local  automation  clouds.
