Summary:

A group of French researchers believe that the sensors and transmitters we wear will route and relay data, not just collect it. We won’t just be connected to the network. We’ll be the network.

Ever wonder what the network infrastructure of the future will be? Try looking in the mirror.

Some day our bodies — or at least the clothing or accessories that adorn them — could become key network nodes in the internet of things. European researchers think that sensors and transmitters on our bodies can be used to form cooperative ad hoc networks that could be used for group indoor navigation, crowd-motion capture, health monitoring on a massive scale and especially collaborative communications. Last week, French institute CEA-Leti and three French universities have launched the Cormoran project, which aims to explore the use of such cooperative interpersonal networks.

Companies like Apple and Heapslylon are exploring the possibility of connected clothes with embedded sensors. We’ve already begun embracing a new era of wearables, such as Google Glass to Fitbit (see disclosure), designed to become extensions of our senses and movements.

All of these devices will become key end-points in the internet of things, but what Cormoran proposes to make them pull double duty. Rather than just remain terminuses, they could route bits to and relay data from each other, becoming a distributed ad hoc network that constantly morphs as we move through physical space.

Better living through distributed networking

Why would you want this kind of network? For one, there is an inherent inefficiency in the point-to-multipoint transmissions that dominate mobile data communications today. Wearable tech usually connects via Bluetooth to a smartphone, which then transmits its info to some distant cell tower. Many medical and connected home devices use proprietary technologies requiring their own dedicated wireless gateways.

A distributed wireless network, however, could aggregate data from hundreds if not thousands of nearby devices and then find the most efficient link to offload that collective data to the internet at large. This kind of collaboration is the same principle proposed by mesh-networking outfits Open Garden and the Open Technology Institute as a means of optimizing wireless systems – if everyone shares their connections and relays each others’ data, then everyone benefits.

But there’s an additional benefit to this kind of collaborative communication: by linking to one another, body area networks could create new useful data about users’ surroundings and location. By measuring the signal strength of nearby connections, the network could determine the precise location of every node, or person, within it.

You can imagine some of the possible applications for such technology. In a busy airport or train station, proximal location-based services could route departing passengers en masse to their proper gates or trains or arriving passengers to the proper baggage claim. City planners could use the technology to track and manage the flow of pedestrian traffic, and emergency agencies could use it to coordinate the evacuation of a building. Sociologists could use it to study group behavior, and game designers and movie CGI could use it to digital map crowd movement.

The big “what if?”

On the flip side, though, creating such collaborative networks has ominous security implications. Our own notions of individual privacy suffer if we know every transmitter in a hundred-foot radius is talking to our devices and even helping to carry our personal data back to the cloud.

If all cars on the highway could talk to one another, they could coordinate their activities, preventing accidents and getting drivers to their destinations faster. But the danger is that these networks would get hacked. Personal information about a car’s driver could get in malicious hands, or data intended to prevent accidents could be falsified to actually cause them.

It’s an exiting project, but Cormoran is going to have deal with similar questions. It will have to not only create the protocols that will allow our body area networks to coordinate, but ensure that the data they relay remains secure and most of the information they share remains anonymous.
