Towards energy efficient mobile communications

The rapid growth and development of wireless communication services and applications corresponds to an increase in associated energy consumption. For broadband wireless network deployment in rural areas affected by unreliability and unavailability of national grid electricity supply, energy efficiency becomes a major design criterion to be considered. In such areas, diesel powered generators are normally used as the main power source, while batteries become the most preferred source of energy to power wireless communication devices. In order to address increasing energy requirements, we propose an energy saving technique for mobile stations (MSs) operating under the wireless broadband access systems in this paper. Our proposed scheme is limited to the power saving class (PSC) of Type I in IEEE 802.16. Our numerical results show that more energy can be saved if the listening interval is considered under non-sleep or awake mode. Categories and Subject Descriptors C.4 [Computer-Communica...
