In ambient-assisted living environments, advanced sensors are used to detect potential problems that may affect the occupant. For a range of unsafe living conditions, characteristic odours arise that can provide early warning of a problem in the dwelling. In this paper, we investigate the concept of smell monitoring in the smart home environment, with particular attention paid to food spoilage. Using a commercially available electronic nose (e-nose) based on a metal-oxide sensor array, the odours associated with five common foods were captured over a seven day period. All foods were readily discriminated at the beginning of the measurement period. However, as the food spoiled, the odour profiles changed significantly. In several cases, the changes for a given food exhibited a clear trajectory in the PCA space. This preliminary work suggests that e-nose technology is a promising candidate for incorporation in the smart home. For widespread adoption, however, future e-nose development must continue to improve current shortcomings such as instability, user intervention, and high cost.

We refer to ‘Home Care Systems’ as the technology and services required to support and realise activities of the network of care. Such technology typically includes sensors, devices, displays, data, and networks, and computing infrastructures which provide the means to collect, distribute, analyse and manage care related information. Such home care support can range from simple stand-alone electro-mechanical alarms installed in a person's home, perhaps to indicate a bath overflowing, to systems integrated into the home's physical infrastructure that monitor patient state, perform sophisticated analyses, deliver customised information to patients and clinicians and support communication among them.

In this paper we present a wearable assistive technology for the freezing of gait (FOG) symptom in patients with Parkinsons disease (PD), with emphasis on subjective user appreciation. Patients with advanced PD often suffer from FOG, which is a sudden and transient inability to move. It often causes falls, interferes with daily activities and significantly impairs quality of life. Because gait deficits in PD patients are often resistant to pharmacologic treatment, effective non+pharmacologic treatments are of special interest.

We present a novel mechanism intended to provide Quality of Service (QoS) for IEEE 802.15.4-based Wireless Body Sensor Networks (WBSN) used for pervasive healthcare applications. The mechanism was implemented and validated on the AquisGrain WBSN platform. Our results show that the QoS performance of the IEEE 802.15.4 standard can be considerably improved in terms of reliability and timeliness for intra-node as well as inter-node scenarios while keeping backward compatibility to ensure interoperability.

Patient-controlled Personal Health Record (PHR) systems may facilitate a patient not only to share her health records with healthcare professionals but also to control her health privacy, in a convenient and easy way. Governed by privacy protection laws, explicit consent/permission of the respective patient is a prerequisite for sharing personal health records. However, in emergency situations, when the patient becomes unable to give consent on her PHRs, healthcare professionals of emergency care units may need to access her health history for better and safer care. In this paper, we have introduced a novel privacy-aware protocol for handling access to patient-controlled PHR by healthcare professionals in emergency situations. The protocol is for the Privacy-aware Patient-controlled Personal Health Record (P3HR) system. It uses strong authentication using health IC cards, authorizes healthcare professionals and embeds emergency access report into the patients health IC card by which we achieve non-repudiation. Use of a dynamic access token in the authorization process protects replay attack. Intuitive privacy analysis shows that the proposed solution can preserve patients privacy from unauthorized parties while granting traceable access to personal health records by authorized healthcare professionals in emergency situations.

As Wireless Sensor Network (WSN) applications become more popular in every day life, the importance of flexible communication protocols rises higher. The limited resources and time-critical nature of WSN must be addressed by the network layer, as one of the most mandatory communication components to support routing capabilities in multi-hop mobile sensor nodes' topologies. WSNs application particularities are analyzed in order to form the design framework for an adaptive routing algorithm that can address all WSN needs. Simulation tests have shown that A.MO.R (Adaptive Multi-Objective Routing) can achieve the WSNs objectives with low communication and energy overhead while meeting QoS and congestion requirements.

SPINE is an Open Source Framework for the design of signal processing intensive (SPI) WSNs. It supports the construction of WSN applications through high-level abstractions and libraries, and allows designers to quickly explore implementation tradeoffs through fast prototyping. This paper describes the architecture of SPINE and presents implementation parameters, such as processing time, memory, bandwidth usage and power consumption that are most relevant for application developers to set tunable parameters and analyze system performance. Finally, the paper presents the performance and the resource usage of a SPINE based posture recognition system for elderly health monitoring.

Dementia affects large number of elderly, manifested with memory impairment symptoms at the onset. This results in difficulties for elderly in scheduling and completing daily activities. In this respect a context-aware reminder system becomes an essential tool in helping elderly navigate their daily activities. Current work on reminder systems typically follows a set of pre-defined activities, organised into a plan. The plan is then used to prompt the elderly to execute specific activities or actions if they have not been completed. However, this is less than an ideal scheme, since the elderly sometimes choose to ignore the reminders due to being engaged in other activities that overlap with the scheduled activities. Therefore, a more flexible schedule is required, that delivers reminders in a context-appropriate manner. Such system must take into account not only the planned activities, but also the current activities of the elderly. We address this problem by monitoring the activities of the elder through our activity recognition system and using this information as a feedback to the reminder system. The reminder system can then decide whether a reminder prompt is appropriate to be delivered or should it be postponed for at a later time. We present the results of activity recognition and discuss how they affect the context-appropriate reminder system.
