Evolution of IoT: An Industry Perspective

Mobile ad hoc networks have evolved since the early 1990s: over two decades. However, the unique concept of wireless deviceto- device networking has now ballooned into a major technology and industry revolution with applications impacting many facets of our lives. In fact, it has paved the way for the Internet of Things and smart cities. In this article, the evolution of IoT through mobile ad hoc networks is discussed, and its penetration into defense, society, and industries through ZigBee, Z-Wave, and other technologies is revealed. Finally, a discussion is presented of IoT architecture, connectivity, cloud, and analytics, and its implications on the realization of future smart cities.
