For the IoT revolution to become reality and fully deliver on its promise, numerous hurdles need first be overcome. First and foremost, there is connectivity. Given the sheer number of devices expected to be interconnected, wiring them up is impractical, and IoT devices will have to communicate wirelessly. Bluetooth Low Energy, Wi-Fi, cellular 3G and 4G, power-line and DECT are but a few of many contenders. Which will it be?
On-device resources pose yet another potential difficulty. Cost restrictions are a key issue, leading to compromises in RAM, processing power and more meaning that existing mobile operating systems and device drivers won't always be easy to migrate due to excessive footprint. This results in a range of limitations that challenge IoT implementations.
Privacy and security concerns, user experience considerations (on IoT devices featuring displays, for example) and software update requirements add to the great many technical and commercial hurdles that need to be overcome. Given that IoT devices are being produced by a myriad of companies, from many different industries including mobile, consumer electronics and heavy industry, it soon becomes apparent that standardization is a must for the full vision of IoT to become reality.
Standardization is singled out as a key driver in UBS’s report “Who Are the Enablers of ‘The Internet of Things’?”, which claims that “adherence to a single standard will be key in enabling the success of the Internet of Things on a global basis” and makes note of “the need for standardization between units, especially in the home” as a prerequisite for the broad adoption of smart devices.
There are plenty of alliances already underway with the intention of establishing standards needed for implementation of IoT. Alliances such as the IIC, OIC, Thread, AllSeen, OMA and MQTT. Redbend has authored a whitepaper that provide details on these initiatives, while shedding light on differences, similarities and potential compatibilities. The paper explores currently existing device management standards, inter-device and proximity application frameworks, and physical short-range network connectivity standards that are expected to play a role in the realization of IoT.
