The issue of energy saving is one of the most critical issues for mobile device. In this paper, we propose a novel scheme to trade off the energy saving, QoS satisfaction, and resource utilization for the radio resource scheduling of downlink traffic in LTE. The proposed scheme takes not only the QoS requirements into consideration but also the channel conditions of user equipment (UE) for better...
For the ATM over WiMax sublayer, traffic of each ATM connection is conveyed by a single WiMax connection. The number of WiMax connections increases along with the ATM connections. Resource allocation overhead and computation complexity also increase as the number of WiMax connections increases. This study discusses the accommodation of multiple ATM connections in one WiMax connection while preserving...
In order to provide seamless handoff for QoS connections in 802.16-2004/WLAN environment, a cross layer design approach is proposed to manage the bandwidth requirement of mobile node during movement. The main concept of the dynamic bandwidth management proposed in this paper is to treat the layer 2 connection of 802.16 as a pipe that aggregates multiple layer 3 RSVP connections with the same class...
