On June 22, 2009, Kevin Ashton introduced a new term “The Internet of Things” (IOT) which has revolutionized the field of electronics engineering. The IOT is a network of smart devices (Fig. 1) that can communicate through internet with other devices/users at remote locations. The applications may vary from pervasive control, health monitoring systems, industrial process control, smart agriculture, food preservation and storage, home security system, smart grid, smart supply chain and many other applications. Overall, the technology facilitates sophisticated living for mankind.  Typical architecture of the IOT network is shown in Fig. 2. The sensors collect data from the surroundings and send it to the internet through gateways, hubs or protocols. Various types of middleware like data distribution service (DDS), Zigbee, RFID, Message Queue Telemetry Transport (MQTT) and others are used to transport data from sensors to the internet. The data is processed using cloud/fog computing. The processed data may be used at remote for generating alarms or controlling actuators for necessary actions.

The technology is likely to reform by 2022, with use of cellular network for communication between IOT devices. As per forecast by Ericsson (https://www.ericsson.com/mobility-report/internet-of-things-forecast), nearly 1.5 million IOT devices will be connected by cellular network by 2022. The requirement of predicting data congestion on networks and proactively planning for bandwidth surges by IOT devices is foreseen. Thus, these new technologies will demand optimizations and developments by engineers for next few decades. A huge demand for engineers with specialization in mobile computing is envisaged.

J.K. Lakshmipat University (JKLU), Jaipur is well-known as Top B. Tech. University in Rajasthan. One of the objectives of the Institute of Engineering & Technology (IET) at JKLU is developing students on industry demanding technologies. As a part of Industry collaboration program in Engineering, the Electronics & Communication department of the IET has recently introduced a state of art embedded systems laboratory equipped with Texas Instruments IOT boards (Fig 3).

This is a pioneer laboratory for engineering students in Jaipur and is being developed as an Innovation Center under Texas Instrument University Program. It shall provide students with hands on sessions on developing innovative projects with smart micro-controllers, sensors and protocols for IOT applications. The institute’s pedagogy is to mobilize the young and bright engineers to develop new ideas and products for the advancement of society. Being one of the the highest and best placement engineering college in Jaipur, we aspire to be develop our students for deployment in this upcoming fields of IOT & mobile computing.
