An overview of Internet of things and wireless communications

Innovations in technology that have enabled efficient wireless tiny devices propelled the concept of Internet of Things. It is expected that mobile data traffic will experience 8-fold growth between 2015 and 2020 and the number of mobile connected devices will reach 11.6 billion by 2020. Main factors of this exponential growth and wide acceptance are the integration of several technologies and communications solutions such as wired and wireless sensor and actuator networks, next generation communication protocols, identification technologies, and artificial intelligence for smart objects. In this work, we explore the role of the IoT in various fields, consider technological aspects, and examine the challenges and opportunities the IoT offers.
