Wireless Body Area Networks (WBANs) applications have emerged as one of the most recent research areas of wireless sensor networks. Lots of research is improving QoS factors in sensor networks. However, QoS requirements vary from application to application, WBAN applications are very sensitive, and QoS issues in WBAN need major concern and focus. This paper outlines the WBANs QoS requirements a...

Today’s mobile data applications aspire to deliver services to a user anywhere anytime while fulfilling his Quality of Service (QoS) requirements. However, the success of the service delivery heavily relies on the QoS offered by the underlying networks. As the services operate in a heterogeneous networking environment, we argue that the generic information about the networks’ offered-QoS may en...

Providing cross-layer quality of service (QoS) for wireless multimedia delivery is challenging task which has attracted intensive research over the years. A fundamental problem in this area is how to map QoS criterion at different layers and optimum QoS across the layers. We present end-to-end QoS architecture for multimedia delivery as well as QoS metrics over wireless links together with chan...

Providing QoS-guaranteed services in current installed networks is an important issue, but only deploying QoS services is not enough to guarantee their success: QoS management must also be provided. Nowadays, policy-based network management (PBNM) addresses this need, but such management is not enough either. Network managers often deal with QoS tasks that cannot be performed using only PBNM. T...

Seiring dengan kemajuan teknologi, mengelola layanan lebih cepat dan mudah menjadi saat Jaringan baik harus mempunyai kualitas diberikan kepada pengguna. Ketika ingin membangun sebuah jaringan me...

The paper presents a general framework and some possible architectures to get a feasible QoS (Quality of Service) mapping among network portions that use different technologies to provide a fixed service level to the terminal users. In general, there is a strong need to have “communication” among portions implementing different QoS technologies: a proper architecture, functionalities and protoc...

In a Quality of Service (QoS) aware communication system, a user is able to choose between various service classes, each with different reliability, predictability, and efficiency degrees. However, until now security has not been recognized as a parameter in QoS architectures and no security-related service classes have been defined. This implies that end-users have no chance of configuring the...

Quality-of-Service (QoS) in Web services considers a service’s nonfunctional characteristics during service specification, discovery, and composition. In order to encourage the development of QoS-aware Web services, we first develop a QoS-aware model, which contains a common set of QoS attributes including response time, throughput, reliability, availability and price etc. Then, based on the at...

In this paper, we consider QoS support in the context of group communications. In particular, we present fundamental properties of QoS in group communications, which, although quite simple, have been widely overlooked and/or misunderstood. Because distributed multimedia applications require flexible QoS agreements, endto-end QoS negotiation will play an important role. We show how such a negoti...
