Abstract—IEEE 802.21 MIH standard defines the mechanism for allowing a mobile device with more than one interface to seamlessly roam between different network technologies. All interfaces are simultaneously turned on for discovering the candidate technologies which cause unnecessary power consumption. In this paper, an On-Off Period (OOP) mechanism for supporting always best connected (ABC) has been proposed by enhancing the monitoring process without any centralized information requirement. The study shows that for the random waypoint mobility pattern and speeds between 1 - 3 m/s, the low off-durations (15 - 30 seconds) significantly save the energy around 54% with low loss opportunity.
