The coverage optimization problem has been examined thoroughly for omni-directional sensor networks in the past decades. However, the coverage problem in directional sensor networks (DSN) has newly taken attraction, especially with the increasing number ...
A directional sensor network consists of a large number of directional sensors (e.g., image/video sensors), which have a limited angle of sensing range due to technical constraints or cost considerations. In such directional sensor networks, the power ...
Differing from general omnidirectional wireless sensor networks, in the directional sensor networks, the effective sensing range of sensors is characterized by directionality and sensing angle. Therefore, there are dissimilar conditions for the ...
