Directional Sensor Network (DSNs) being a subdivision of WSN has attracted researchers a lot due to its wide deployment in visual monitoring applications as the continuous technical advancements have enabled us making use of low-cost camera sensors. But because of the inherent random deployment of these camera sensors, the effective area coverage is reduced. Therefore, the effective area coverage...
The positioning of sensors in Wireless Sensor Networks WSNs affect coverage, communication cost and resource management. The effectiveness of these networks is determined to a large extent by the coverage provided by the sensor deployment. Coverage is an important optimization objective in WSN deployments. Sensor positioning alludes to the capabilities of WSNs to ‘adapt’ and ‘respond’, in order to...
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,...
Wireless sensor networks (WSN) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. The focus of monitoring application is to acquire and verify information about enemy capabilities and positions of hostile targets. Monitoring applications related to security and reliability requires guaranteed k-coverage of the area at all times. A...
