system bandwidth savings will be explored with
multiple traffic flows. It can be significantly use-
ful for connections competing for shared system
resources. This chapter presents an overview of
the e-Health/m-Health services and applications.
A methodology for designing a multi-hierarchical
architecture of telemedicine services is proposed
and it is shown how the WiMAX technology can
support the data transmission within telemedicine
environments. In addition, a new efficient video
distribution technique over IEEE 802.16/WIMAX
network is proposed. The developed technique is
evaluated for different scenarios. Results of the
simulation show that this new approach can be
successfully exploited for distribution of stream-
ing video over WiMAX networks.

FUTURE RESEARCH DIRECTIONS

Future research will be focused on the video broad-
casting distribution model over WiMAX access
networks. The impact on the capacity increase and
