QoS management for dependable sensory environments

Abstract

Sensory environments for healthcare are commonplace nowadays. A patient monitoring system in such an environment deals with sensor data capture, transmission and processing in order to provide on-the-spot support for monitoring the vulnerable and critical patients. A fault in such a system can be hazardous on the health of the patient. Therefore, such a system must be dependable and ensure reliability, fault-tolerance, safety and other critical aspects, in order to deploy it in real scenario. Also, the management of the infrastructure resources must be efficient and the eventual system reconfiguration must be reliably performed. This paper encounters some of these issues and proposes a component platform with specific support for several QoS aspects, namely fault tolerance, safe inter-component communication and resource management. The platform adopts the Service Component Architecture (SCA) model and defines a Data Distribution Service (DDS) binding, which provides the fault tolerance and the required safety-ensuring techniques and measures, as defined in the IEC Multimed Tools Appl

A Component-Based Approach for Securing Indoor Home Care Applications

“…The sensitive nature of the managed patient data demands reliable data transmission (R7) as well as secure data transmission (R8). The former ensures message integrity over non-safe channels [ 11 ] and protects against non-intentional data corruption, whereas the latter ensures that medical data related messages are properly identified, authenticated, and protected against deliberated data modifications.…”

“…In concrete, two of them arise as particularly challenging: safety and security. Safety must be considered as mandatory when dealing with aspects such as computerized prescribing and medication [ 10 ] or remote monitoring of physiological data [ 11 ]. In this case, the integrity of the transmitted data must be protected against eventual data corruption.…”

Run-time reconfigurable middleware in device network architecture

“…Reconfiguration of the system, particularly in run-time, is a thoroughly studied topic [1][2][3][4]. Multiple strategies have been developed to address reconfiguration issues such as potential downtime of the system components during reconfiguration, response time increase, data throughput capacity decrease and management of reliability and fault tolerance.…”

QoS Aware Middleware Support for Dynamically Reconfigurable Component Based IoT Applications

“…The concepts of service and service implementation [9] have inspired the concepts of logical component and physical component. The middleware architecture is the result of previous work [10,11], as well as the low level QoS management mechanisms [12,13], the definition of the basic services [14], and the basic fault tolerance mechanisms for the middleware components [11,15]. This paper is focused on the QoS aware dynamic reconfiguration algorithm proposed in Section 5.…”
