  • Clear channel reporting and assisting orphaned nodes in a wireless network
    Patent number: 8838761
    Abstract: In a wireless network, a device regularly communicates with at least one other node or device: generally this is its parent. If a problem with communication is detected, the device is preferably able to autonomously carry out a procedure to reacquire the network. In one embodiment, if a device is unable to communicate, it enters a temporary failsafe mode until that problem can be rectified. The device is suitably able to carry out a survey of local conditions in order to assist both it and the network to find a suitable alternative channel and, if a device is unable to immediately reconnect it broadcasts the result of its survey, the Network Environment Status (NES) message, in the hope that another device on the network will hear it. This Status message may then be used by the network to select an alternative channel.
