Monitoring of the activities of daily living of the elderly at home is widely recognized as useful for detection of new or deteriorated health conditions. However, the accuracy of existing indoor location tracking systems remains unsatisfactory. The aim of this study was therefore to develop a localization system that can identify a patient's real-time location in a home environment with maximum estimation...
Operating a mobile robot using the signal strength of a Radio Frequency (RF) system and/or line-of-sight distances to other known points or RF stations is a challenging task. This problem has been traditionally solved by several approaches suggested in the literature. Among the most common shortcomings of those approaches are the use of excessive number of sensors or multiple reference RF stations...
This paper is based on sensor network theory aim to localize the mobile sensor node. Our mobile sensor node is used to apply ubiquitous service in indoor environment. Therefore the localization and path planning for mobile sensor node is an essential factor. Path planning technology plays an important role in mobile sensor node. The mobile sensor node must successfully find a collision free path to...
