Large mobile experiment

Today, we counducted an experiment with a total of 81 mobile sensor nodes. The experiment involved lots of preparations, but produced a lot of data. We hope to process them soon.

Large experiment scheduled

On June 6th, we plan to conduct a large scale experiment involving 90 people wearing our mobile nodes and the additional 130 static nodes.

20 more nodes arrived

We have just received 20 more static nodes for our testbed. We plan to use the nodes in an upcoming experiment. More information soon...

Internet of Things

Recent developments in miniaturization, energy efficiency, and low-power wireless communication suggest that we are on the verge of a futuristic vision: a so-called Internet of Things. By embedding tiny, “smart”, wireless devices into the surrounding physical objects, the Internet of Things will allow not only humans, but also those every-day objects to directly communicate with each other. In this way, without human intervention, the networked objects will be able to collaborate in making our lives more convenient, environment friendly, and secure.

For example, once the devices in our office furniture detected that we have just left for home, they could signal the devices embedded in electric appliances in the room to turn off or hibernate the appliances, thereby saving energy. On our way home, the devices embedded in our car could communicate with similar devices in other nearby cars to ensure a safe distance from those cars and to avoid traffic jams. When passed over, devices embedded in the road surface a few kilometers from our house could instruct the devices controlling the house to prepare for our arrival. In effect, upon arrival we could, for instance, take a hot bath without either waiting for water to warm up or wasting energy on keeping water warm when we were away.

Wireless Sensor Networks

A sensor node One of the technologies that can make the above vision a reality are wireless sensor networks (or simply sensornets): collections of tiny devices integrating computing, wireless communication, and sensing. A device of this sort – a wireless sensor node – is an inexpensive microcomputer, typically no larger than a coin. Powered by an equally small battery or by energy harvested from the environment, it can work unattended for months or even years. This size and ultra-low energy consumption facilitate embedding such nodes into the surrounding physical world. Furthermore, to have the ability to interact with their surroundings, the nodes are equipped with low-power sensor and actuators. Sensors allow a node to locally observe selected aspects of its environment, such as the temperature, the presence of living organisms, or changes in the magnetic field. Actuators, in turn, enable controlling the object a node is embedded in, for example, switching a light, changing the volume of fuel delivered to a car engine, or activating parts of an irrigation system of a large farm.

An essential component of each node is a low-power radio, which the node uses to communicate with other nearby nodes. In this way, tens, hundreds, or even thousands of nodes can form a wireless network through which they can exchange data with each other and computers or other devices connected to the Internet. As a result, while an individual node has only local and limited sensing, decision making, and actuation capabilities, a wireless sensor network as a whole can provide a global picture of its surroundings, can make more informed decisions based on this picture, and can control the surroundings globally in a coordinated fashion.

We are researching the protocols that would allow tiny wireless sensor nodes to be a part of the Internet. I want to know more...
