Recently, wireless mesh networking is attracting great interest from the wireless community. With several favourable characteristics, such as self-organization, self-configuration, self-healing and easy maintenance, WMNs is a cost- effective approach to support high-speed last mile connectivity and ubiquitous broadband access. Despite recent advances, many research issues remain. The use of a mesh architecture with multi-radio and multi-channel (and possible multi- antenna) have brought new challenges in the design of MAC and routing protocols. Also, new application scenarios, requiring low-latency communications, are urging researchers to address enhanced QoS support. In this project, we will develop and test such a QoS-enhanced protocol.
Due to the receding cost of manufacturing, Radio Frequency Identification (RFID) systems are used in a variety of applications to tag and track physical objects. A typical RFID system operation involves numerous tags to be present simultaneously in the interrogation zone of a single reader. Any responses from the tags can collide, leading to retransmission of tag information that results in increase in the access delay. Besides, readers physically located near one another may interfere each other. Such reader collision must be minimized. In this project, we will design a procedure to deal with tag and reader problems, while taking environmental effects into account.
