Power conservation for maximizing the lifetime of the limited battery powered ad hoc networks are one of the most important factors in a network design. Transmitting at high power may assure network connectivity but sacrifice network lifetime and increases the interference as well. Meanwhile transmitting at lower power reduces the interference on the expense on network robustness. We investigate the...
The traffic in the high-speed wireless multimedia network will be a mixture of voice, video and data messages having a large variety of characteristic and inherent requirement. The present work is a medium access control protocol for time division-code division multiple access system to distribute the available bandwidth among the mixture of different traffic classes depending upon their quality of...
In this paper, we study medium-access-control (MAC) protocols with quality-of-service (QoS) support, topology-transparent broadcast scheduling (TTBS), in multihop time-division multiple-access (TDMA) ad hoc networks. TTBS focuses on the QoS provisioning that each node can successfully transfer the same packet to all the other nodes within its communication range simultaneously (broadcast traffic)...
In this paper, the Quality of Service (QoS) for multimedia traffic of the Medium Access Control (MAC) protocol for Ultra Wide-Band (UWB) networks is investigated. A protocol is proposed to enhance the network performance and increase its capacity. This enhancement comes from using Wise Algorithm for Link Admission Control (WALAC). The QoS of multimedia transmission is determined in terms of average...
