Temperature compensated time synchronisation in wireless sensor networks

  title={Temperature compensated time synchronisation in wireless sensor networks},
  author={Davide Brunelli and Domenico Balsamo and Giacomo Paci and Luca Benini},
Time synchronisation is a fundamental service in many distributed systems such as wireless sensor networks. Non-uniform operating temperature among deployed nodes and dynamic variation of the temperature represent the major cause of clock drift in the nodes of a network. Presented is a low-overhead clock synchronisation for WSNs based on a new temperature compensation algorithm (TCA). The TCA is local and uses a temperature sensor to remove the effects of environmental temperature changes and… CONTINUE READING
