In recent years, with advance in wireless communication technology, sensing technology, micro-electronics technology and embedded system, wireless sensor network (WSN) can be used for various application areas, such as home health care, military and industry. The localization service which provides the location information of mobile user is one of important service provided by WSN, because many applications...
Security plays an important role in the ability to deploy and retrieve trustworthy data for a wireless sensor network. Secure coverage is an effective defense against attacks which take advantage of a lack of deployment information. In this work, on the basis of improved genetic algorithm, a novel algorithm is proposed to guarantee the effect of secure surveillance. Comparison and simulation results...
The recent advances in radio and embedded system technologies have enabled the proliferation of wireless microsensor networks. Such wirelessly connected sensors are released in many diverse environments to perform various monitoring tasks. The effectiveness of these networks is determined to a large extent by the coverage provided by the sensor deployment. The positioning of sensors affect coverage,...
This paper presents a novel Virtual Circle Combined Straight Routing (VCCSR) algorithm for a mobile sink to collect data in wireless sensor networks. Tree-based routing is a common scheme to collect data from sensors to a sink. Most of the previous proposed tree-like aggregation approaches are not suitable for mobile sink, because the routes between sink and sensors have to be reconstructed when a...
