The proliferation of wireless services and anytime anywhere communication providing always-on connectivity, mobile devices are getting smaller and smarter. Therefore, Third-Generation (3G) wireless standards IEEE 802.16e should provide very efficient energy conservation mechanisms to achieve longer battery life while providing enhanced user experience and Quality of Service (QoS). The emerging IEEE 802.16e standard provides a new sleep mode operation for Mobile Stations (MS) to address energy efficiency. In sleep mode, the energy consumption of MS may be reduced by introducing a sleep cycle.
