Synchronization in On-Chip Sensor Networks

Clock power has become one of the greatest limitations in distributing a global clock from a central clock buffer though the chip due to increasing clock speeds and die sizes. The goal is to develop a low-power clock synchronization scheme.
One way is bio-inspired distributed synchronization. Without a centralized clocking, the timing of each node dynamically evolves under other nodes' interactions and finally achieves synchronization. Another way is to perform synchronization only when communication is needed.
