ABSTRACT:
Provided is a method for mobile sensor node roaming in an environment of first and second adjacent wireless sensor networks having a plurality of sensor nodes. The method includes the steps of: periodically performing energy detection scan and active scan operations, at the mobile sensor node forming an association with a parent node of the first wireless network, and obtaining energy values of selected channels and link quality indications (LQIs) for the channels; when the sensor node moves to the second wireless sensor network, periodically performing energy detection scan and active scan operations, at the sensor node, and obtaining energy values of selected channels and link quality indications (LQIs) for the channels after movement; comparing, at the sensor node, the energy values and link quality indications (LQIs) of the selected channels before and after movement.
