Energy-efficient scheduling and MAC for sensor networks, WPANs, WLANs, and WMANs

Energy efficiency is very important for all mobile/wireless devices due to mobility of these devices. The recent evolution of sensor networks, Wireless Personal Area Networks (WPANs), Wireless Local Area Networks (WLANs), and Wireless Metropolitan Area Networks (WMANs) has yielded a demand to improve energy-efferent scheduling algorithms and energy-efferent Medium Access Control (MAC) protocols. The effort to improve energy-efferent scheduling and MAC is linked with many technical challenges including compatibility with legacy networks, complexity in implementation, and practical values in real market, etc. The need to address energy saving solutions and provide timely, solid technical contributions of these networks establishes the motivation behind this special issue.
