The internet of things will be marked by a notable absence of business or technical models in coming years, according to market researchers Gartner. Through 2018, the company predicts there will be no dominant internet-of-things ecosystem platform. Most IoT projects will continue to contain custom elements and there won't be any dominant technology service providers in the IoT space.

Garter forecast that there will be 4.9 billion "connected things" in use this year, up 30 pc from 2014. By 2020, the total will be 25 billion.

Connected cars are set to be a major element in the internet of things, the market researchers said, predicting that, by 2020, one in five vehicles on the road will have some form of connectivity on board. That is equal to about 250 million connected vehicles.

"In-vehicle wireless connectivity is rapidly expanding from luxury models and premium brands to high-volume mid market models, "James Hines, Gartner's research director, said in a press release.

Hines cited a wide range of new automotive requirements resulting from the connectivity trend. Said the Gartner executive: "The increased consumption and creation of digital content within the vehicle will drive the need for more sophisticated infotainment systems, creating opportunities for application processors, graphics accelerators, displays and human-machine interface technologies."
