Shared networks are now able to support a wide range of applications, including real-time multimedia. This has led the networking community to consider a wider range of network Quality of Service (QoS) guarantees and pricing schemes. To date, the QoS required by networked multimedia applications has been described in terms of technical parameters. We argue that, in order to maximize the realize...

This article deals with networked control systems (NCSs) whose shared networks have limited communication capacity and are prone to data losses. Our contributions two-fold. First, we present necessary sufficient conditions on the plant controller dynamics network parameters such that there exist purely time-dependent periodic scheduling sequences under which stability of each is preserved for a...

This paper addresses control design in networked control system by considering stochastic packet dropouts in the forward path of the control loop. The packet dropouts are modelled by mutually independent stochastic variables satisfying Bernoulli binary distribution. A sliding mode controller is utilized to overcome the adverse influences of stochastic packet dropouts in networked control system...

Networked control systems (NCS) provide many advantages for idustrial development. For larger scale systems and more complex systems usage of NCS’s will become mandatory. However usage of networked control systems introduces time-delay uncertainty in closed-loop system dynamics. These time delays are caused by the time sharing of the communication medium as well as computation time necessary fo...

background annual four to five thousand babies are born with hearing loss in the iran. hearing impairment is a disability that affects the quality of life of people with this problem. these individuals need to support from family and friends because of their specific conditions that this received support has impact on their quality of life. this study was conducted to assess the status of perce...

The number of heterogeneous networked applications is constantly increasing. It is likely that network resources will have to be partitioned according to the different Quality of Service (QoS) demands made by the users of these applications. One way of implementing a partitioned network – favored in technical literature − is in terms of quality-based pricing (e.g.[1],[2],[3]). Most published pr...

Assessing video content transmitted over networked content infrastructures becomes a fundamental requirement for service providers. Previous research has shown that there is no direct correlation between traditional network QoS and user perceived video quality. This paper presents a study investigating the impact of individual packet loss on four types of H.264 main-profile encoded video stream...

Object-oriented frameworks help reduce the cost and improve the quality of networked applications by reifying software designs and pattern languages that have proven effective in particular application domains. This chapter illustrates what frameworks are and compares them with other popular software development techniques, such as class libraries, components, patterns, and model-integrated com...
