    Abstract: A network manager of a wireless mesh network is configured to selectively enable or disable communication services provided between devices over the network. The selective enabling or disabling of services may be based on the monitoring and enforcement of license terms set according to license information embedded within the wireless network node(s) or access point(s) of the network. In operation, the network manager retrieves the license information from the node(s) and/or access point(s) of the network, and establishes license terms based on the retrieved license information. In turn, the network manager selectively enables or disables network services, such as by throttling communications relayed between the user application and the nodes, or between nodes, if the license terms are not respected.

    Abstract: The stability of a channel in a wireless network is evaluated at a node. Upon transmitting a packet from the node on a network channel, a first counter associated with the channel is incremented. Upon receiving an acknowledgment packet responsive to the transmitted packet, a second counter associated with the channel is incremented. A stability metric for the channel is computed based on values stored in the first and second counters. Additionally, interference on a channel of the network is measured at a node. Upon determining that no packet is received during a predetermined time-period on the channel, a received signal strength (RSS) is measured on the channel at an end of the predetermined time-period. Alternatively, upon determining that a packet is received during the predetermined time-period on the channel, the RSS is measured on the channel following completion of the transmission of the packet on the channel.

    Abstract: A wireless mesh network is provided with equipment and methods for monitoring and enforcement of license terms. The network includes a plurality of wireless network nodes, a wireless access point, and a network manager in communication with the access point and with the network nodes via the access point. At least one of the network nodes and the access point includes license information embedded in the device hardware, and the network manager provides services to the wireless network subject to license terms determined based on the license information embedded within the network node or access point. Additionally, the network manager is in communication with a user application external to the network, and relays communication between the user application and the wireless network. The network manager modulates communications relayed between the user application and the wireless network subject to the license information embedded within the network node or access point.
