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.
