A low-power wireless network involves a master and a plurality of RF-enabled fluorescent lamp starter units. In each of a plurality of intervals, a starter wakes up and listens for a beacon, regardless of whether a beacon is transmitted during that interval or not. The starter operates in a low power sleep mode during the majority of the interval. The master can transmit during the beacon slot time of any interval, but typically only transmits frequently enough to maintain starter synchronization. If the master wishes to communicate with the starters with reduced latency, then the master can transmit a beacon in the next interval. Beacon slot time is varied within the interval (for example, from interval to interval or from group of intervals to group of intervals) in a pseudo-random time-hopping fashion known to both the starters and the master, thereby reducing persistence of collisions with similar networks.

The present invention extends to methods, systems, and computer program products for reducing persistence commands. An application host sends a persistence command to a persistence provider for processing. If the persistence provider recognizes and is able to carry out the persistence command, the persistence provider incorporates the semantics of the persistence command into the command implementation strategy; otherwise, the persistence provider employs a command reduction processor. The process of executing or reducing persistence commands is repeated until the persistence provider has produced and completed execution of a command implementation strategy equivalent to the original persistence command or until an unprocessable persistence command is reached for which no further reductions are possible. A command reduction processor can provide alternative persistence commands or an algorithm of persistence commands with semantics equivalent to an originally received persistence command.
