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. |
