Packet-oriented access to cellular networks enables us to deliver multimedia content to mobile users. As cellular networks will continue to deliver circuit switched voice for some time to come, care must be taken to avoid interference between these delivery mechanisms, while maximizing the range of services and the number of users. Smart delivery of multimedia content involving agents running i...

VoIP (Voice over Internet Protocol) is a growing technology during last decade. It provides the audio, video streaming facility on successful implementation in the network. However, it provides the text transport facility over the network. Due to implementation of it the cost effective solution, it can be developed for the intercommunication among the employees of a prestigious organization. Th...

Network is essentially a distributed information system providing access to shared data objects between networking applications running on different nodes. As the Internet gains its rapid growth, new and more demanding networking applications start to emerge such as voice over IP, storage over IP and media streaming. To cope with the demands of these applications, the underlying network process...

1 Research Assistant of the Fund of Scientific Research Flanders (FWO-Vlaanderen) Abstract In this paper we discuss how OPNET can be applied in advanced networking education, enhancing the practical skills of future network engineers. At the K.U.Leuven Master students in Electrical Engineering focusing on Telecommunications have to complete a complex networking design about Voice over IP, Wirel...

We extend the modeling heuristic of (Harsha et al. 2006. In IEEE IWQoS ’06, pp 178 – 187) to evaluate the performance of an IEEE 802.11e infrastructure network carrying packet telephone calls, streaming video sessions and TCP controlled file downloads, using Enhanced Distributed Channel Access (EDCA). We identify the time boundaries of activities on the channel (called channel slot boundaries) ...

In everyday life we often listen to one sound, such as someone's voice, in a background of competing sounds. To do this, we must assign simultaneously occurring frequency components to the correct source, and organize sounds appropriately over time. The physical cues that we exploit to do so are well-established; more recent research has focussed on the underlying neural bases, where most progr...

In this paper we are proposing an effective encryption technique for high volume streaming data which has been sent over various communication links throughout the network. Applications requiring high volume of streaming data transmission include audio-video conferencing or Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). In general, whenever we use these types of ap...

Steganography in streaming media differs from steganography in images or audio files because of the continuous embedding process and the necessary synchronization of sender and receiver due to packet loss in streaming media. The conventional theoretical model for image steganography is not appropriate for explaining the security scenarios for streaming media based stegosystems. In this paper, w...

Although lot streaming scheduling is an active research field, lot streaming flexible flow lines problems have received far less attention than classical flow shops. This paper deals with scheduling jobs in lot streaming flexible flow line problems. The paper mathematically formulates the problem by a mixed integer linear programming model. This model solves small instances to optimality. Moreo...
