Abstract
This invention discloses a power saving method for battery-powered Zigbee devices. When a Zigbee device loses connection with a Zigbee network, it will search for the Zigbee network until it finds and rejoins the network. However, the Zigbee network may not be available for a sustained period of time due to a long power outage. To avoid wasting the battery power of the Zigbee device on performing too many searching operations, the Zigbee device waits for a waiting period after performing a search operation and before performing a subsequent search operation and the waiting period prior to each subsequent search incrementally increases while more subsequent searches are performed.
