MyriaNed

Each message is repeated and duplicated towards all nodes that span the network; it spreads like a virus (hence the term epidemic communication).

This is a very efficient and robust[2][3] protocol, mainly for two reasons: Nodes can be added, removed or may be physically moving without the need to reconfigure the network.

The network may even be heterogeneous, where several types of nodes communicate different pieces of information with each other at the same time.

Furthermore, MyriaNed is enabled to update the wireless sensor nodes software by means of “over the air” programming of a deployed network.

Every cell knows what to do with this message (increase heart rate, constrict blood vessels, dilate air passages) and does not sent a confirmation.

In potential the complete set of information (e.g. sensor values, control data) is available to every node in the network.

By using an intelligent strategy, called shared state, this information is stored as a distributed database in the network.

The advantage of such a topology is reliability, and coping with mobility, because of the redundant communication paths in the network.

Setup and configuration is kept to a bare minimum because of the bottom-up approach utilized in the self-organizing network.

There is no notion of a coordinator or network manager entity compared to technologies such as Zigbee or WirelessHART.

MyriaNed has an extremely small stack, uses low calculation power and does not need a large amount of energy.

Chess Wise, one of the companies behind DEVLAB, used the MyriaNED technology as an early base for Mymesh, their network protocol.

This technology is used to connect, control and analyze thousands of devices simultaneously within demanding environments.
