The emerging wireless vehicular communication technology is intended to improve safety and comfort of transportation systems. Different types of traffic information could be delivered through vehicle-to-vehicle and vehicle-to- infrastructure communications. This paper proposes a Quality-of-Service (QoS) supported multi-channel MAC scheme for Vehicular Ad Hoc Networks (VANETs), which can adaptively...
The IEEE 802.16e is a compatible and reasonable technology to solve the last mile access problem. Since the multiple services in the system are connection-oriented, it is crucial to provide effective admission control and resource allocation mechanisms to guarantee the quality of service (QoS) of the system. In this paper, we investigate the joint bandwidth reservation and admission control in the...
In this paper, we perform a tele-traffic queueing analysis for OFDM subcarrier allocation in wireless multiservice networks. For this purpose two call admission control algorithms, the batch blocking scheme and the partial blocking scheme, are proposed. Call connection requests are classified into two different types, narrow-band and wide-band. For either class of calls, the traffic process is characterized...
