| As mobile devices and wireless networks are
becoming ubiquitous, the interest of users to deploy real-time
applications, e.g., online gaming or Voice-over-IP in such
environments is also increasing. Due to the difference between
traditional and wireless networks, in particular in terms of
available bandwidth and network structure, the concepts used for
supporting real-time applications in both networks are different.
This paper gives an overview of the key technical challenges that
are fundamental and need to be solved in order to easily support
real-time applications in wireless and mobile environments. In a
first step, issues related to service provisioning in mobile
networks are discussed. This is followed by a look at the Quality
of Service supported by wireless networks and possible techniques
for improving it. Finally, concepts for securing the
communication between the users of real-time applications in
wireless and mobile networks are presented. For each of these
issues, we provide a detailed analysis and an overview of the
state-of-the-art. Moreover, we illustrate the main points using
distributed online games as an example. |
