Techniques in a mobile communication device for signal monitoring in a wireless communication network are described. The mobile device operates for communications over a communication channel of the wireless network. During operation, the mobile device periodically obtains measurements of signal quality of the communication channel at a rate R. In addition, the mobile device obtains a measurement of velocity or acceleration of the mobile device. In response to an increase in the measure of velocity or acceleration, the mobile device increases the rate R. Conversely, in response to a decrease in the measurement of velocity or acceleration, the mobile device decreases the rate R. The measurements of the signal quality may be used to determine whether to initiate a handover to a different wireless network. In one illustrative environment, the initial wireless network is a wireless local area network (WLAN), the other wireless network is a wireless wide area network (WWAN), the signal quality is a received signal strength indication (RSSI) of the communication channel, and the monitoring involves obtaining samples of the RSSI.
