报告摘要： Wireless sensor networks (WSNs) are fundamentally changing today’s practice of numerous scientific and engineering endeavors by enabling continuous monitoring and sensing physical variables of interest at unprecedented high spatial densities and long time durations. This has significantly impacted broad fields such as environmental sciences, ecosystems, hydrology, natural hazards, precision agriculture, smart building, and smart city. We focus on outdoor WSNs that are deployed in harsh or even hostile environments such as mountainous areas, hilly watersheds, and forests, which presents great challenges in WSN design, development, operation and management, because of the severe resource constraints (e.g., battery power, bandwidth, memory size, and CPU capacity) of tiny sensor nodes and the uncontrolled deployment environments. In this talk, I will discuss, from an engineering perspective, some unique challenges in the wireless sensor networking, including energy-efficient routing in WSNs for data collection, heterogeneous WSN energy profile, and over-the-air reprogramming WSN nodes in real-world deployments. I will then share my group’s work and describe our novel approaches in addressing these challenges, and present our results using a real-world long-term environmental WSN testbed deployed in Pennsylvania USA.
