Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The specific focus of this book is on mechanisms that affect the VoIP user satisfaction while not explicitly involved in the media session (i.e. the coded speech). This relates to the extra delays introduced by the security and the signaling protocols used to set up an authorized VoIP session and to the disruption caused by the user mobility that may take place during the session. This book thus investigates and proposes techniques for realizing time-efficient control mechanisms for VoIP. One important aspect within this book is the use of correlated error processes or random error processes or both to model the FER in the channel in order to evaluate the delays incurred by control mechanisms in different error situations.

This item is printed on demand - it takes 3-4 days longer - Neuware -The convergence of different types of traffic has preceded the convergence of systems and services in a wireless heterogeneous network. Voice and data traffic are usually treated separately in both 2G and 2.5G wireless networks. With advances in packet switching technology and especially with the deployment of wireless heterogeneous systems, both speech and data traffic are carried over wireless links by the same IP-based packet-switched infrastructure. However, this combination faces some challenges due to the inherent properties of the wireless network. The requirements for good quality VoIP communications are difficult to achieve in a time-varying environment due to channel errors and traffic congestion and across different systems. The provision of VoIP in wireless heterogeneous networks requires a set of time-efficient control mechanisms to support a VoIP session with acceptable quality. The focus of Voice over IP in Wireless Heterogeneous Networks is on mechanisms that affect the VoIP user satisfaction while not explicitly involved in the media session. This relates to the extra delays introduced by the security and the signaling protocols used to set up an authorized VoIP session and to the disruption caused by the user mobility during the session. Voice over IP in Wireless Heterogeneous Networks thus investigates and proposes cross-layer techniques for realizing time-efficient control mechanisms for VoIP: signaling, mobility and security. 256 pp. Englisch.
