Show moreWireless networks have been an essential part of communication and a very hot research interest in the last century. It is a truly revolutionary paradigm shift, enabling multimedia communications between people and devices from any location. Wireless networking is becoming increasingly ubiquitous, there has been a major development in communication hardware and protocol stack for better quality of service, increased throughput, reduced latency, reduced energy consumption, security, etc. As wireless networks continue to develop, usage has grown day-by-day and it becomes a critical part of home, business and industrial infrastructure. To meet all these increasing demands, growing wireless networks and standards researchers are providing new networking technologies. However, these technologies must be tested before they can be released for mainstream use. As academic research in wireless networking relies heavily on simulation, the accuracy depends on the fidelity of the models used in simulation. Even the well-known simulators used in academic research, like ns-3 and qualnet, fails to provide accurate behavior of the signal propagation and wireless channels. Without high confidence in the accuracy of wireless network simulation tools, it is difficult to make concrete progress in cross-layer protocol optimization research. In this thesis, we built a versatile wireless networking testbed, which can support variety of applications. This testbed supports Multi-Radio Multi-Channel (MRMC) wireless mesh networks and can implement various multi radio routing protocols. We have made several modifications to the wireless interface device drivers to improve the performance of multichannel protocols. Furthermore, we will discuss the details of our testbed and its implementation. M.S. in Electrical and Computer Engineering, July 2011 Show less
