Brief announcement: gradient clock synchronization in sensor networks

  title={Brief announcement: gradient clock synchronization in sensor networks},
  author={Lennart Meier and Lothar Thiele},
We examine gradient clock synchronization [1], where the difference between any two network nodes' clocks is required to be upper-bounded by a non-decreasing function of their distance: A node has to be synchronized better to nearby nodes than to faraway nodes. We look at the gradient property in a system model that is typical for sensor networks, provide a lower bound for the achievable synchronization quality in our model, and discuss its relation to the bound in the model from [1].
