Design and Implementation of a Wireless Sensor Network for Smart Homes
Wireless sensor networks (WSNs) have become indispensable to the realization
of smart homes. The objective of this paper is to develop such a WSN that can
be used to construct smart home systems. The focus is on the design and
implementation of the wireless sensor node and the coordinator based on ZigBee
technology. A monitoring system is built by taking advantage of the GPRS
network. To support multi-hop communications, an improved routing algorithm
based on the Dijkstra algorithm is presented. Preliminary simulations have been
conducted to evaluate the performance of the algorithm.Comment: International Workshop on Mobile Cyber-Physical Systems (MobiCPS

A High-confidence Cyber-Physical Alarm System: Design and Implementation
Most traditional alarm systems cannot address security threats in a
satisfactory manner. To alleviate this problem, we developed a high-confidence
cyber-physical alarm system (CPAS), a new kind of alarm systems. This system
establishes the connection of the Internet (i.e. TCP/IP) through GPRS/CDMA/3G.
It achieves mutual communication control among terminal equipments, human
machine interfaces and users by using the existing mobile communication
network. The CPAS will enable the transformation in alarm mode from traditional
one-way alarm to two-way alarm. The system has been successfully applied in
practice. The results show that the CPAS could avoid false alarms and satisfy
residents' security needs.Comment: IEEE/ACM Internet of Things Symposium (IOTS), in conjunction with
