This book shows how networking research and quality engineering can
be combined to successfully manage the transmission quality when
speech and video telephony is delivered in heterogeneous wireless
networks. Nomadic use of services requires intelligent management
of ongoing transmission, and to make the best of available
resources many fundamental trade-offs must be considered. Network
coverage versus throughput and reliability of a connection is one
key aspect, efficiency versus robustness of signal compression is
another. However, to successfully manage services, user-perceived
Quality of Experience (QoE) in heterogeneous networks must be
known, and the perception of quality changes must be understood.
These issues are addressed in this book, in particular focusing on
the perception of quality changes due to switching between diverse
networks, speech and video codecs, and encoding bit rates during
active calls.
