We present design and implementation of CyPhyS+, a comprehensive, low-cost and standards compliant Cyber-Physical System (CPS) using 6LoWPAN based Internet of Things for remote health monitoring of elderly staying in old-age homes. It is a closed-loop system that incorporates an end-to-end reliable message transfer scheme for the resource constrained environment, data security, real-time medical signal processing and data analytics, and FHIR/HL7 compliant web services. The low power operation of CyPhyS+ allows the CPS an extended uptime, ensuring connectivity to the medical sensors, via the Internet, anytime/anywhere. The end-to-end reliable and secure messaging mechanism of CyPhyS+ does not necessitate intermediate application end-points at the old-age homes. This enables easy deployment with low operational overheads, scalability as well as easy introduction of newer applications or application upgrades. The paper describes system architecture, design and implementation details of software and hardware sub-systems. HealthMote, a power efficient Bluetooth-6LoWPAN mote was designed and deployed as a sub-system. We describe the novel low power end-to-end multi-stage message reliability scheme for UDP based sensor applications that does not require intermediate application-aware devices within the network. The experimental results presented show the efficacy of the approach. CyPhyS+ employs an application performance aware SNMP based network monitoring for robust operations of the 6LoWPAN multihop network. It incorporates a 128-bit AES, CBC-MAC based encryption and authentication mechanism for security and privacy. CyPhyS+ is compliant with FHIR/HL7 standards framework, with support for RESTful FHIR, and medical data analytics of ECG. We report on the extensive field trials carried out across a city.
