In the integrated Wireless LAN (WLAN) and cellular networks, power efficiency is one of most important aspects as in existing wireless networks. Especially, we note that idle state, a mobile device with dual interfaces needs to receive periodic beacons from access point downlink control information base station, resulting significant consumption. To save power, propose saving scheme Hibernation mode completely turn off WLAN interface during instead entering Power Save (PS) it on only when there need data. However, if turned even for momentary traffic, must repeat turning continuously, dissipating power. Thus, also develop Mobile IPv6 (MIPv6)-based signaling long-lived traffic. It shown via simulations proposed results better efficiency.
