Project Title: Wireless Multimedia Mesh Networks Prospective advisors: Primary advisor: Ast/P Peter Han Joo CHONG (EEE), Co-advisor: A S Madhukumar (SCE) 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. Requirements for the candidate: Knowledge of wireless networks such as mobile ad hoc network. Understanding of digital media applications and their characteristics Optimization techniques Good at C/C++ programming, NS-2 simulation tool
