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...
Gas detection is the main concern in factory or home safety. Wireless sensor network, sensors combined with a microprocessor and wireless communication, can be applied in gas detection. There are a lot of researches discuss the fixed gas sensors in certain location, however, this system still requires that people carry gas detectors to patrol the entire environment due to sensors failure or sensing...
