Description
In wireless networks it is beneficial for the nodes to share
a notion of time, at least in a periodic (clock) sense. In
existing cellular networks, nodes may get their timing from
a centralized server. In networks without centralized
control, however, such as ad hoc and sensor networks, time
synchrony has to be generated in a self-organized manner.
Each node decides its preferred timing based on information
on the timings of other nodes. In the literature,
synchronization algorithms based on (pulse) coupled
oscillators have been widely studied, mostly in the setting
of a fully connected network. In this talk, synchronization
in networks with nearest neighbor coupling is studied.
Synchronizatino based on pulse coupled oscillators is
compared to simple cyclic averaging algorithms.
