Layered multicast is a promising technique for broadcasting adaptive-quality TV video to heterogeneous receivers. While several layered multicast approaches have been proposed, prior work has identified several problems including significant and persistent instability in video quality, arbitrary unfairness with other sessions, low access link utilization due to conservative bandwidth allocation...

Studies on the cross-layer design for efficient multimedia delivery with QoS assurance over wireless networks utilize the differentiated service architecture to convey multimedia data. The common approach is the partitioning of multimedia data into smaller units, and then maps these units to different classes for prioritized transmission. The partitioned video units are prioritized based on its...

One in five people are living with disabilities in the United States, yet little is known about the quality of care they receive and barriers they have to accessing care. The Agency for Healthcare Research and Quality (AHRQ) showcased new approaches and technologies for improving the care of this priority population at a session during its Annual Conference in September. It also recently releas...

In this paper, we present a fast and scalable pipelined priority queue architecture for use in high-performance switches with support for fine-grained quality of service (QoS) guarantees. Priority queues are used to implement highest-priority-first scheduling policies. Our hardware architecture is based on a new data structure called a Pipelined heap, or P-heap for short. This data structure en...

Quality of Service (QoS) is essential in Mobile Ad Hoc Networks (MANETs) in order to satisfy communication constraints, e.g. delay, as set in real-time applications. Traffic from such applications is normally treated as high-priority in contrast to non delay sensitive applications such as FTP or e-mail, which are largely delay tolerant and have their flows treated as low-priority in the network...

In this paper, we model a call center as a preemptive-resume priority queue with time-varying arrival rates and two priority classes of customers. The low priority customers have a dynamic priority where they become high priority if their waiting-time in queue exceeds a given service-level time. The performance of the call center is measured by the mean number in system for the two customer cla...

Recently, huge number of e-mails is sent and received. These e-mails are classified into spam and non spam ones which are processed with the same priority. To guarantee a higher priority service to non-spam e-mails than that is provided to spam e-mails, a two-priority queue scheme was proposed. There are some drawbacks in the two-priority queue scheme such as it fails to provide a Quality of Se...

Carrier sense multiple access and its variants have been widely used in mobile ad hoc networks. However, such access cannot guarantee the quality of real-time traÆc. This paper presents a distributed medium access control protocol that provides priority based multimedia access to wireless ad hoc networks. First, a priority classi cation scheme is used to distinguish the higher-priority frames (...

Facilitating loan and advances to customers is the main stream of banking business. The loans are advanced by banking institution to different segment of their market. These segments primarily fall under priority and non-priority sectors, in former sector bank are directed to grant as per guidelines by the Reserve Bank of India. Furthermore, the rise of non-performing assets (NPAs) in banks is ...
