Project Description:
As the wireless communication becomes popular, we notice that wireless mesh networking is a suitable
candidate for the communication infrastructure to provide future high-data-rate (HDR) multimedia
applications anywhere and anytime. Wireless mesh networking allows wireless routers to interconnect
with each other. Inside this wireless mesh network (WMN), users can transfer and access to any type of
digital media applications through the wireless connection from router to router. In addition, WMN is
able to provide digital media applications through Internet services for the entire covered area without the
limitation of the wired IP connection.
The objective of this project is to conduct research on WMN to provide seamless and smooth
transmission for various types of digital media applications through wireless transmission. Two types of
extreme applications will be focused first; real-time video and interactive gaming, which are the most
challenging in terms of their QoS consideration. The type of wireless network can be based on WiFi or
WiMax networks. In this project, several work needs to be considered such as networking issues, QoS
optimization and spectrum sensing. Proposed research work to be done includes:



Networking: How to transfer data from the source router to the destination router through a
number of intermediate routers is not an easy task! A simple and efficient routing protocol to
select intermediate routers needs to be developed in order to support such HDR real-time video
transmission. Adaptive optimized routing algorithm is needed to change the routing path from
time to time to provide seamless and smooth transmission for some application.
QoS optimization: Since various digital media applications are co-existence in the network and
each of them requires different types of QoS requirement such as delay, data rate, error rate and
cost. An efficient QoS algorithm is needed to satisfy their QoS requirement and at the same time
it can maximize the network capacity.
Spectrum access: Another important issue is to deal with the spectrum selection and usage. While
the available spectrum becomes more and more scarce, the assigned spectrum is significantly
underutilized in a practical communication environment. In such scenarios, radio nodes become
intelligent agents that make opportunistic use of radio spectrum so that multiple systems can
occupy the available frequency space in a non-interfering manner. However, interference in radio
systems is a reality and one has to cancel/avoid caused by other communication systems sharing
the same frequency band. It is in this context, this project also aims to design efficient algorithms
for spectrum sensing and sharing for radio nodes in a mesh environment.
