دانلود What Can I Do Here? IoT Service Discovery in Smart Cities

Abstract

The vision of smart cities and IoT is an environment blanketed  with  interconnected,  software-enabled  devices.  Unlike software installed  on personal devices,  however, people  may not know about services in the environment, or may not even be the intended  users.  People  lack  a  unified  way  to  discover  software services  in  a  smart  city  infrastructure,  and  the  current  device-centric approach to IoT is inconsistent with the growing network and software services associated with these devices. In this paper we outline changes needed in the current IoT framework to shift to a service model for IoT. We describe how, similar to users of a personal computing device, users can define their preferences, install  services,  and  manage  the  data  that  is  generated  and consumed  by  services.  In  this  framework,  service  preferences provide  a  basis  for  proper  service  discovery.  As  an  illustration of  the  proposed  model,  we  provide  modifications  to  the  well established Auto-ID Object Name Service and Physical Markup Language  architecture  to  demonstrate  how  a  practical  system can  support  the  concept  of  IoT  services  and  discovery.
