“Advances in Multi-Sensor Fusion for Body Sensor Networks: Algorithms, Architectures, and Applications II”
The Information Fusion Journal is planning the2nd edition of thespecial issue onAdvances in Multi-Sensor Fusion for Body Sensor Networks: Algorithms, Architectures, and Applications.
Multi-sensor data fusion embraces methodologies, algorithms and technologies for combining information from multiple sources into a unified picture of the observed phenomenon. Specifically in the context of Body Sensor Networks (BSNs), the general objective of sensor fusion is the integration of information from multiple, heterogeneous, noise- and error-affected sensor data source to draw a more consistent and accurate picture of a subject’s physiological, health, emotional, and/or activity status.
About a decade ago wireless sensor network (WSN) technologies and applications led to the introduction of BSNs: a particular type of WSN applied to human health. Since their inception, BSNs promised disruptive changes in several aspects of our daily life. At technological level, a BSN comprises wireless wearable physiological sensors applied to the human body (by means of skin electrodes, elastic straps, or even using smart fabrics) to enable, at low cost, continuous and real-time non-invasive monitoring. Very diversified BSN applications were proposed during the years, including prevention, early detection, and monitoring of cardiovascular, neuro-degenerative and other chronic diseases, elderly assistance at home (fall detection, pills reminder), fitness and wellness, motor rehabilitation assistance, physical activity and gestures detection, emotion recognition, and so on. On of the main key benefits of this technology is the possibility to continuously monitor vital and physiological signs without obstructing user/patient comfort in performing his/her daily activities. Indeed, in the last few years, its diffusion increased enormously with the introduction at mass industrial level of smart wearable devices (particularly smart watches and bracelets) that are able to capture several parameters such as body accelerations, electrocardiogram (ECG), pulse rate, and bio-impedance.
However, since many BSN applications require sophisticated signal processing techniques and algorithms, their design and implementation remain a challenging task still today. Sensed data streams are collected, processed, and transmitted remotely by means of wearable devices with limited resources in terms of energy availability, computational power, and storage capacity. In addition, BSN systems are often characterized by error-prone sensor data that significantly affect signal processing, pattern recognition, and machine learning performances. In this challenging scenario, the use of redundant or complementary data coupled with multi-sensor sensor data fusion methods represents an effective solution to infer high quality information from heavily corrupted or noisy signals, random and systematic error-affected sensor samples, data loss or inconsistency, and so on. Most commercially available networked wearables assume that a single device monitors a plethora of user information. In reality, BSN technology is transitioning to multi-device synchronous measurement environments. With the wearable network becoming more complex, fusion of the data from multiple, potentially heterogeneous, sensor sources become non-trivial tasks that directly impact performance of the activity monitoring application. In particular, we note that the complex processing chain used in BSN designs introduces various levels of data fusion with different levels of complexity and effectiveness. Only in recent years researchers have started developing technical solutions for effective fusion of BSN data.
