Multi-level clustering for clock skew optimization
Clock skew scheduling has been effectively used to reduce the clock period of sequential circuits. However, this technique may become impractical if a different skew must be appli...

Toward Clock Skew based Wireless Sensor Node Services
Clock skew is defined as the rate of deviation of a device clock from the true time. The frequency of a device's clock actually depends on its environment, such as the tempera...

A case against routing-integrated time synchronization
To achieve more accurate global time synchronization, this paper argues for decoupling the clock distribution network from the routing tree in a multihop wireless network. We find...
