A wireless mesh network is a network where the nodes in the network help other nodes achieve coverage and connectivity by forwarding messages on behalf of others.

Street lighting systems is an example of where a wireless mesh network is needed. A single-hop network would not provide enough coverage, so the lights help each other to reach out.

A wireless IPv6 mesh network in the wild.

The picture above shows an installation of a Thingsquare IPv6 mesh in the wild. (Although our system is known to be able to run on really, tiny devices operated by a single coin-cell battery, this particular installation does not use those low-power mechanisms as street lights have access to power.)

The big challenge with such a large wireless network is to understand what is going on – and how to develop the software that makes them tick.

In this article we look into how we develop such large-scale systems at Thingsquare and the tools we use. We push the envelope with a 100-hop network, which is larger than what we typically would see in real-world installations.

How to Make a Wireless Sensor Live for a Year on One Tiny Coin Cell Battery

When it Comes to Lifetime, Responsiveness is More Important than Data Rate

Power consumption literally is matter a life and death for battery-powered devices. Making devices last for a long time will reduce deployment costs. And being able to predict the lifetime in advance makes planning easier and allow us to replace batteries at scheduled intervals.

Today we will use the Thingsquare system to make a wireless TI Sensortag live for a year on one coin cell battery.

We see that making the right choices in software can make a stunning 400x difference in power consumption – two orders of magnitude – even with an already extremely power-efficient hardware.

We use the Thingsquare system’s built-in power consumption monitoring mechanism that allow us to predict the lifetime of a device without having to run it until the battery depletes – which would take us at least a year.
