Abstract
A system and method for monitoring a predetermined condition in a harsh environment, includes wireless sensor nodes each having a physical clock and a soft clock. The sensor configured to detect the predetermined condition. Each wireless sensor node remains in a sleep mode, then independently, when a triggering event is true, the soft clock evolves a value of a dynamical local time variable using time variable values communicated by random other of the wireless sensor nodes that are within a single hop based on the harsh environment, infers from its dynamical local time variable the communication instant at which the dynamical local time variable is closest to the time value of the gateway node, and initializes the physical clock using the value of the dynamical local time variable at that instant to generate and communicate the local node time through the gateway node to the end-user device.
