Measurement and Design on Data Collection of Low-Duty Cycle Wireless Sensor Networks
PhD Thesis Proposal Defence Title: "Measurement and Design on Data Collection of Low-Duty Cycle Wireless Sensor Networks" by Mr. Zhichao Cao ABSTRACT: Wireless sensor networks (WSN), which consist of numerous energy-constrained sensor nodes, are mostly duty-cycled and rely on multi-hop routing to collect data. Data collection mechanism is thus a building block of WSN systems. The performance of WSNs nowadays, however, are far restricted by the limited understanding and the underachieved design of data collection mechanisms. This proposal is based on real-world WSN measurements and mainly addresses two key issues that emerge from real applications, namely bursty-loss aware lazy forwarding, and end-to-end delay measurement, modeling and optimization. I develop theoretical principles and practical approaches to address the above issues. Through extensive real-world implementations and trace-driven experiments, I evaluate those proposed methods and verify the efficiency. As the future work towards my dissertation, this proposal also includes the research plan concerning the impact of network dynamics, such as link dynamics and down-stream routing changes, to avoid the potential risk.
