The future mobile wireless networks are expected to merge most types of services
including Internet and multimedia applications, based on Internet protocols toward IP.
We can see the explosive growth in the use of wireless computer equipped with
wireless network interfaces conversing with each other using IP. Nevertheless, current
TCP/IP protocols do not perform well in wireless environment because of mobile
environment’s nature.
The current Internet protocols offers only best-effort service, i.e. no Quality of
Service (QoS including delays, jitters and losses), thus there have been considerable
works in the research community in order to provide QoS in the Internet. There are
many commercial media streaming players that are currently developed for Internet,
such as Realplayer, Vxtreme and Microsoft Netshow. Although they claim to be
adaptive, full QoS support, but no analysis is available to prove any claims. In order
to extend service models for Internet, two major models, Integrated Services [1] and
Differentiated Services [2] have been proposed in recent years. In these models, the IP
layer is modified for providing better QoS to various applications or classes of
applications.
The main reason for the degradation of QoS in the Internet is congestion. Several
works proposed to use resource management in combination with fair queuing
disciplines, with traffic shaping methods and admission control mechanisms at
different levels. Another approaches are adaptive (i.e. network-aware) applications at
application level. On the other hand, many new protocols such as Loss-Delay
Adjustment Algorithm LDA [3], Rate Adaptation Protocol RAP [4] and TCP Friendly
Rate Control Protocol TFRC[5] have been developed for multimedia applications. The future mobile wireless networks are expected to merge most types of services
including Internet and multimedia applications, based on Internet protocols toward IP.
