How IoT and Internet Will Converge

Connecting machines, devices, sensors, and other things of daily use with an intelligent network and make sense out of them, has huge promises to change everyday life. As can be expected by taking in our entire world and attempting to change it one stroke and with one magic wand is unrealistic, challenging and cause for chaos in the short term.


For business decision makers and technology providers, some measure of clarity and progress can be made by understanding the challenges of applying IoT to business. In this article we analyze two principal challenges in making this happen. 

Technology protocols: 

The challenges of IoT rest in the ability to connect sensors and devices to the Internet. To connect to the Internet any device and application must use Internet Protocol stacks. It is for this reason that devices called Internet Gateways have been created that connect to non IP devices and networks on one side and the Internet driven applications, devices and networks, on the other side. By doing so, Internet Gateways need to be tailored for the type of local networks and local applications that they manage on one side and how they connect to the Internet on the other side. 

Over the years, countless Internet Protocol driven applications, software tools and diagnostic kits have been developed and exist, that can be applied to IoT devices and sensors, with or without much adaptation. This will help to get the IoT environment up and running in a short period of time, relatively speaking. That is provided they are in the same Internet Protocol environment. The basis for the development of Internet Protocol applications till now has been growing availability of large computing power and significant memory capacity to manage complexity of the Internet Protocol based applications. And all this within localized high cost nodes like desktops, notebooks, smartphones, tablets, amongst others.

 This is the exact antithesis of the IoT environment as it exists today, which is low cost, low power consuming, low computing capacity, and distributed computing nodes.

Networking architecture: 

Whenbuilding an IoT network it is essential to plan and look ahead. It is alsoimportant to converse with all departments associated with the benefits andoperations of the IoT network and applications. When dealing with tens andhundreds of thousands of sensors and devices in any IoT project, it is pivotalto have a networking strategy to ensure the end result is managed chaos insteadof unmanaged chaos. 

Industryconsultants who have gone through such projects point out, IoT application andnetwork designs need to be built looking at requirements five years from now.When in doubt the rule of thumb is design networks for a requirement that is10X the number of devices that are connecting in now. Another importantconsideration is to design the wireless environment thinking about what willhappen in that specific industry over next five years. While the benefits ofsuch best practices are self-evident, industry surveys show that suchdiscussions are not happening as much as they should. If all else fails, theminimum rule of thumb to apply, think big for IoT. 

Lookingahead into the requirements for IoT type of networks there is a significantchange in the way devices will communicate. More often than not, communicationsignals will hop from device to device, to enter and leave the network ofdevices, connecting into and out of their mesh network.

Utilizinga number of hops between devices rather than the conventional hub to spoke jumpwill become the standard for most IoT applications and networks. The key hereis multiple and random paths between IoT devices, based on predefinedalgorithms, rather than a fixed point to point hop. This saves power, savescost, builds scale, and builds redundancy. 

Thesenetworks are called mesh networks and the devices are called wireless nodes.Since connectivity within mesh networks rely on each other, their efficiencygrows with an increase in the number of devices. Mesh networks become moreefficient as the number of wireless nodes inside them increases. This is theopposite of what happens with the hub and spoke, star network arrangement. Assilicon technologies enhance the computing capabilities of IoT sensors,devices, machines and appliances, they will increasingly become more Internetcompatible. At that stage the two worlds will come together in exponentialfashion and the true power of IoT will become a reality.
