To meet the diverse quality-of-service (QoS) requirements of emerging multimedia applications, communication networks should provide end-to-end QoS guarantees. QoS routing is the first step towards this goal. The route computing overhead caused by on-demand calculation of QoS routes, especially in large networks with heavy traffic, is a concern and can(More)
STUDY DESIGN PRISMA-guided systematic review. OBJECTIVES To provide a comprehensive framework of the current animal models for investigating spinal cord injury (SCI) and categorize them based on the aims, patterns and levels of injury, and outcome measurements as well as animal species. SETTING Sina Trauma and Surgery Research Center, Tehran University(More)
The rapid advances in telecommunication and Internet technologies is the driving force behind the emergence of a new generation of network-oriented multimedia applications such as Internet telephony and real time video applications. To successfully deploy these new applications, the communication networks should be QoS capable so that network resources such(More)
Wireless LANs are becoming increasingly popular. While the technology offers wireless connectivity, it offers minimal or no quality of service (QoS) to multimedia applications. We propose a virtual QoS MAC layer (VQML) between MAC and networking layers to provide QoS. The proposed VQML architecture is implemented in a Linux platform and tested in an(More)
STUDY DESIGN This is a Delphi study. OBJECTIVES Defining variables that potentially influence the outcomes of an animal study regarding pathophysiology of traumatic spinal cord injury (TSCI). SETTING This study was conducted in Iran. METHODS A modified two-round Delphi study was conducted. As the first round, an initial questionnaire was developed on(More)
