Inspiration of Myrianed
• Biology
• Self-organization
Myrianed, initiative DEVlab
• Why? Why is it better?
• Reliability, redundancy
• Scalability, many nodes, fully meshed (thousands in one building)
• Dynamic/moving nodes
• Self-configuring, self-healing
• no single point of failure
Myrianed benefits
Gossip
Resilience
(Global) time
built-in recovery

Measured topology in our office
New effects
• adding or removing functions without structural building effects
• easy to extend with additional sensors or actuators
• easy to extend with new integral functions; via the internet
• making building control user/person dependent:
• e.g. zorg, ziekenhuis, etc
• refurbishment of existing office, internal relocation in office
• integral usage of all sensor information
Challenges
• Defenders of the old walls of independent systems
• lighting, by calculation (fixed) or active/adaptive control
• fire alarm: rules and regulations
• burglar alarm: rules and regulations
• climate, room level, personalized,
Current Myrianed ideas/products
• Door and window switches, support climate control and burglar alarm
• Light control + energy measurement, switching power outlets at night
• Light/climate control not only on movement detection but also on active seat
detection
• Asset tracking within buildings, such as: where are how many chairs?
• Your ideas:
New models, new business, new cooperation
• Wireless network based on new organizational model: self
• Revolutionary method for building automation
• New opportunities for cooperation between several companies
• Nederlandse ontwikkeling, met trots internationaal brengen
• NL implementatie van Internet of Things, of beter: Network of Things
• energy savings through active control of power outlets
Light bulb implementation in hardware
• E-27 socket with power supply (6 W) and wireless in one PCA
• Dimming (color temp) and on/off as part of the LED bulb itself
Myrianed
Architecture possibilities
• Network programming
• Local rules, like switching lights on specific sensors
• Local rules for heating valve control based on temp sensor
• Internet “cloud” programming
• Time analysis of energy usage, optimizing
• Burglar alarm or other type of warning systems
How to control?
• local functions are easy in the network
• sensor(s) switches a group of lights “on”
• sensor controls valve
• global functions are in the server
• total energy consumption
• asset inventory
Gossip brings advantages
• Scalability: Gossip protocols are
inherently scalable. Each node performs
a fixed set of operations at a fixed rate,
regardless of the network size.
• Network load balancing: In a gossip
protocol, each and every node
communicates with a limited number of
peers, in order to provide a service.
• Resilience to node failures: Gossip
protocols are inherently redundant: a
node is likely to be contacted by more
than one peer in a given execution.
• Resilience to transient network
failures: Due to the broadcast to peers,
multiple paths are explored in a gossipbased protocol. This makes the protocol
highly resilient to link failures.
• Symmetric nature: Gossip protocols
are symmetric by nature. No node is
playing a specialized role.
• Simple low cost management: In order
to operate, each node only needs to
maintain knowledge about its
neighbors. This membership is much
simpler to maintain than structures with
much stronger constraints (such as a
spanning tree).
