Towards Wireless Building Management Systems: A Design Requiring No Change to the Upper-Layer Building Protocols
 
题 目:Towards Wireless Building Management Systems: A Design Requiring No Change to the Upper-Layer Building Protocols
报告人:王丹博士,香港理工大学
摘 要:
    There are many recent efforts in developing wireless or partially wireless Building Management Systems (BMS). A key difference from developing a brand new wireless sensor application, where one can design the system from scratch, is that there exist wired building management systems and there is a full set of upper layer protocols developed and standardized. Ongoing studies on wireless BMS usually develop smart sensor hardware and re-design protocols from bottom up. Such approach requires a long time for standardization and adoption.
    In this talk, we study from a new direction by proposing a general framework that converts existing wired sensor network into wireless without change of upper layer protocols and the existing hardware. The key ideas are an asynchronous-response framework to maintain the control plane of the upper layer protocol intact, and a modular design to prioritize and schedule data flows in case of link quality and throughput variation. Our design can become a supplement for existing studies towards developing wireless building management systems. We evaluate our system using both comprehensive simulations and experiments with real BMS hardware, software and protocols running on top. We made a field deployment by integrating our system into the BMS of the FG building of The Hong Kong Polytechnic University. The system operated smoothly during our five-hour deployment.
