Networking Wireless Sensors Using Smart Antennas
Thesis Context and Objective. Because of inherent limitations in WSN hardware and the unreliability of the wireless channel, networking WSN devices poses several challenges to reliability, latency, and throughput. A solution to the problem may come from the use of “smart” antennas. While traditional antennas spread the transmission power equally in every direction, smart antennas can direct the wireless beam towards specific directions, achieving far better reliability and energy efficiency.
The networked embedded systems group at SICS (http://www.sics.se/nes)—one of the leading European
research groups in WSNs—is actively investigating the use of smart antennas in WSNs. We designed and built a
cheap, yet flexible smart antenna prototype that can be easily integrated with existing WSN nodes. Early experiments in real-world settings proved the functioning of our antenna prototype. The objective of the thesis is to continue the work in this field along different possible directions, depending on the student’s interests and background. For instance, we would like to carry out a full characterization of the smart antenna prototype to build models for use in WSN simulators. Another possibility deals with the design and implementation of routing protocols expressly conceived to take advantage of the smart antenna’s capabilities. Nevertheless, the topic
may also open up unforeseen opportunities for interesting research.
Candidate Requirements. We are looking for a top, creative student with a strong interest in wireless networking and
sensor networks. Good C programming skills are required. The work will be performed in an international environ-
ment. Therefore, good communication skills in English are required.
Starting Date and Application. The thesis work shall start as soon as possible. For the application, please send
us an up-to-date CV, courses taken and grades. In addition, we appreciate an article, paper, thesis or other relevant documents you have written in order to judge your ability to express yourself in English. Please send your application to [email protected] If the thesis work is satisfactory, we will pay a one-time fee once the thesis is approved by the university.
