increased electricity demands, crumbling physical infrastructure of buildings,
roads, water sewage, power grid, and declining health care services. Moreover,
major trends indicate the global urbanization of society, and the associated
pressures it brings, will continue to accelerate. One of the approaches to
assist in solving some of the challenges is to deploy extensive IT technology.
It has been recognized that cyber-technology plays a key role in improving
quality of people's lives, strengthening business and helping government
agencies serve citizens better. In this white paper, we discuss the benefits
and challenges of cyber-technologies within "Smart Cities", especially the IoT

benefits and challenges of IoT cyber-technologies on smart cities physical
infrastructures and their human stakeholders. To point out the IoT challenges,
