The use of a Wireless Sensor Network (WSN) has increased in the last years in many different fields. One of the main advantages of WSNs is the fast data acquisition thanks to the data gathering systems that can archive, process and send the collected data through Internet or store them in different formats. These data archiving and processing is very useful for water quality monitoring. The monitoring...
Monitoring applications have been deployed throughout the years using either wired or short and long distance wireless technology. The wireless technologies itself have been developing and on increasing trends throughout the years. This study discusses on the comparison on two types of wireless technologies to be deployed in the healthcare industries for monitoring patient's vital signs, which are,...
An intelligent femtocell-based sensor network is proposed for home monitoring elderly or people with chronic diseases. The femtocell is considered as a small sensor network which is placed into patient house and consists on both mobile and fixed sensors disposed on three layers. The first layer contains body sensors attached to the patient that monitor different health parameters, patient location,...
The current paper proposes a hybrid sensor network for indoor monitoring and discusses the way both body and ambient wireless sensors are integrated into this network.
