Keywords: Wireless local area network (WLAN) IEEE 802.11 Energy efficiency Power management a b s t r a c t In recent years, IEEE 802.11 wireless local area networks (WLANs) have been widely deployed, and more and more mobile devices have built-in WLAN interfaces. However, WLAN employs the carrier sense multiple access with collision avoidance (CSMA/CA)(More)
—Broadband wireless access systems usually provide flexible sleep-mode operations for mobile stations to conserve energy during idle or active modes. For example, the IEEE 802.16e offers several sleep-mode classes that can be applied to mobile subscriber stations (MSSs) to reduce their power consumptions for different applications. Unfortunately, previous(More)
In this paper, a novel initial videos allocation scheme and a dynamic load balancing strategy are proposed for a distributed video storage server in order to increase the availability and reduce operation cost. The initial allocation scheme determines the allocation of video replicas on the servers to achieve static load balance and to obtain a(More)
The Embedded Software (ESW) consortium under the Very-Large-Scale Integration (VLSI) Circuits and Systems Education Program which is supervised by the Ministry of Education (MOE) of Taiwan was initiated in 2004 to develop and promote embedded software education. One of the major missions for this consortium is to develop and deploy embedded software(More)
