Abstract:
1. A wireless network device comprising: a node constructed and arranged to transmit and receive wireless signals in a wireless network, the node including a direct sequence spread spectrum radio that is adapted to transmit and receive wireless signals on a plurality of different frequency channels, and wherein the node uses multiple different frequency channels in a sequence for communication with at least first and second devices in the wireless network, wherein the node is configured to perform a connectivity assessment for at least the first and second devices in the wireless network that indicates a measure of quality of wireless communication between the node and the first and second devices in the wireless network, the connectivity assessment being performed for each respective one of the first and second devices at multiple, different frequencies, the connectivity assessment being used to determine a first communication relationship between the node and the first device in the wireless network, and a second communication relationship between the node and the second device in the wireless network, the first and second communication relationships being established for future communication between the node and the first and second devices on multiple frequency channels, respectively, such that if a communication with the first device at a first frequency is not acknowledged, the node retries the communication using a strategy that includes resending the communication to the second device at a second frequency.
