Goal of the session: identifying research issues
Application areas
- Smart grids
The goal is to balance the load across the network. A phase-locked system is sufficient (not necessarily in-phase).
- Wireless systems
Synchronization within 1% of the slot duration is sufficient.
Main general issues
- Robustness to faulty nodes
- Does the system return in place after a node fails/does not follow local rules?
- Fault tolerance
- Scalability
- Hierarchical synchronization, i.e. clustering, can be applied on top of SO Sync to limit scalability issues.
- Implementation
- Synchronization as a primal form of coordination
- Optimum solution
- Finding a method that is most robust and scalable in meshed networks
Open issues
- Better understanding of inhibitory behavior in meshed networks
- Why is inhibitory coupling worse in sparse networks?
- Dynamic networks
- Hassler and Toroczkai, 2005 (distributing locals onto computers s.t. they finish computing at the same time)
- Stochastic oscillators
- MEMFIS
- Mathematical proof for excitatory coupling in meshed networks. First clue in Restrepo and Ott paper, Phys. Rev. E
- Time to synchrony increases with the network diameter
- Discrete Kuramoto model
