For everyone who is interested in an IoT technology benchmark for smart building services, here is my list. I would say this should interest building services engineers, building specifiers and OEMs in particular. Your feedback is highly appreciated.

1. Requirement What should you be asking as an OEM? Why is this important?
SECURE Is the network secure by design?
2015 was “The Year of the Cyber Attack”. 2016 wasn’t any less
confronting. Cyber Security should be a concern for any user or owner of
connected devices. Adding network connectivity to any “thing” can
certainly provide great value but also brings with it potential risks.
SCALABLE
How scalable is it and is that scalable enough? What determines
scalability?
Depending on your business case/ use case you would want to scale up
and integrate new devices simple and easy - with as little
reconfiguration, extra interfaces, gateways, routers as possible.
RESILIENT
How resilient is the network? Does it have self-organizing/ self
healing qualities? Are there single point of failures? (number of
master/ slave relations in the network?)
The level of resilience impacts your down-time, maintenance costs,
operational costs and the end-user experience.
MOBILE
How easy can moving assets and people be tracked and traced?
And with what accuracy? And how important is this to you now
and in the future?
Buildings are highly dynamic environments. Assets and people move
everywhere all the time. Can your IoT platform handle that (most can't -
> IP based)
ADDRESSABILITY
How many nodes (smart assets) can be addressed in 1 group?
(e.g. Can lights can be a part of more than one light scene)
The addressability impacts the scalability but also the simplicity of
commissioning and the flexible application of nodes to fit one or more
purposes.
INTEGRATED
(publish +
subscribe)
Can nodes also communicate with each other? (Can sensors and
actuators exchange real time set-points and states? )
If nodes can both publish and subscribe to messages, the network
becomes highly agile (easy to commission/ flexible)
INDEPENDENT
Does the network depend on the cloud/third party providers? Or
can it operate as self-operating network? How much control do
you have over the ownership of the data/ network?
The level of independency impacts the security and operational costs.
Depending on the infrastructure (back office in the cloud?) and the
business model of your solution provider you will have more or less
control over your data, the network and its costs.
RADIO AGNOSTIC
On what frequency does the protocol operate? And at what
strength (mWatts)? What are the duty cycles?
It can get crowded at certain frequency. Can the protocol operate on
other frequencies, and what are the parameters that influence its
reliability and its distortion rate?
OVER-THE-AIR
VERSION UPDATES
How easy can devices be updated. In case of a system update,
would you need to update devices manualy? Or does the network
allow for OTA updates?
Depending on the amount of nodes and updates an OTA update feature
can have a huge impact on operational costs and down time. Imagine
having to manually update all devices?

SECURITY
Strong encryption and authentication (Aes CCM) protects the
network traffic from eavesdropping and tampering. Each node
has a unique id, allowing it to obtain authenticated
updates.Chess Wise uses Hardware security Modules (HsM),
similar to those used in the banking industry. This provides
optimal protection of all product keys, both public and private,
with a 128 bit AES encryption standard.
SCALABILITY
Contrary to iP based, hierarchical networks, MyriaMesh is
heterarchical and scalable to more than 10,000 different
devices, allowing one network to control ‘everything’ for
seamless platform integration.
RESILIENCY
The network’s collective intelligence deploys and restores (new)
nodes automatically. in short: MyriaMesh is self-organizing and
self- healing and has no single point of failure.
MOBILITY
Contrary to IP based connectivity platforms, MyriaMesh allows for
easy tracking of mobile of nodes for example to support track &
trace applications.
?
ADDRESSABILITY
MyriaMesh can address 65k nodes in 1 group. All nodes are
equally able to reach peers, groups or all nodes. One device
can be a member of 8 groups simultaneously.
PUBLISH &
SUBSCRIBE
CONTROLLAYER
MyriaMesh’s universal network language enables sensors and
actuators to exchange real time set-points and states (e.g turn
light at 70% during daylight-state) that allows for simple
(re)configuration.
?
INDEPENDENCY
A MyiaMesh network can operate independently. Its nodes
have a collective intelligence that -together- manage the
network’s individual applications. Connection to
complementary cloud (management) applications is simple
but optional.
OVER-THE-AIR
VERSION
UPDATES
MyriaMesh is radio agnostic. Its protocol operates on short
range (smart building) as well as long range frequencies
(smart city/ outdoor).
