发明名称 Accelerated rejoining in low power wireless networking for logistics and transportation applications
摘要 Techniques are disclosed for enabling accelerated rejoining of network devices in a low-power wireless network after a connection to the low-power wireless network is lost. Embodiments generally include, for a network device that periodically conducts scans for beacons on the low-power wireless network, increasing the frequency, or scanning rate, at which the scans are performed. After a certain period of time, if the network device has not joined the low-power wireless network, the network device can implement a different scanning rate until it rejoins with the network. Additional techniques may be used to reduce power usage and preserve the structure of a portion of the low-power wireless network that has become disconnected with the rest of the network.
