IEEE 802.11e constitutes the “state of the art” standard for providing QoS to multimedia traffic in Wireless Local Area Networks (WLANs). However, it has been proven inadequate in certain network conditions (high load). Several mechanisms improving its performance have been proposed in the past years. Most of them focused on altering the static nature of resource allocation specified in IEEE 802.11e...
The explosive demands of multimedia services have been grown up to support delay-sensitive applications, e.g., VoIP and streaming using codec. When a mobile node (MN) moves across different types of networks, the codec should be effectively adapted according to the significant change of network condition, i.e., throughput and delay. Therefore, in this paper, we propose a codec adaptation for vertical...
