agnostic to the form factor, operating

system or service provider.

The member companies are

contributing software and engineering

resources to the development of a

protocol specification, open source

implementation, and a certification

program, all with a view of

accelerating the development of the

IoT.

What makes this slightly different is

that it is intended to cover a range

of existing and emerging wireless

standards and be compatible with a

variety of operating systems, rather

than just being one radio technology.

The OIC is competing directly with

the AllSeen Alliance that is backed by

chip giant Qualcomm, Microsoft and

also networking giant Cisco. This is

built around the AllJoyn open source

technology developed by Qualcomm

and now has 50 companies signed

up, including Sharp, D-link and

Wilocity. The aim of AllJoyn is that

the core building blocks and services

for discovery of new devices, how

they connect and security can be

used across both wireless and wired

networks for connecting up devices.

The aim is to standardize the approach

at a higher level to allow devices with

different technologies to interact,

so the focus is on service-level

discovery, capabilities broadcasting,

remote procedure calls, interface

sharing and message handling, along

with the ability to react to dynamic,

ad-hoc network changes.

AllSeen is probably slightly ahead of

other consortia such as OIC and the

Thread Group with more members

and a software development kit to

allow applications developers and

end customers to work with the

technology. However the amount

of software development needed to

bring different technologies together

with a low power implementation may

be a challenge for many customers,

along with the focus mostly on the

US.

Conclusion

Low power is becoming a driving

force behind the development

of technology for the Internet of

Things. Trading off data rate, packet

complexity and wireless duty cycle to

reduce the power requirements and

extend battery life is leading to a split

of protocols and standards, backed

by a range of different consortia.

It is now down to the different

applications, particularly in the

smart home, and the cooperation of

different suppliers that will determine

the protocols with the critical mass

and so the cost effective solution.
