Most of the applications deployed over WSNs require strong coverage requirements, especially those related to the detection and tracking of distributed events. In this paper, we use the Voronoi partition of the monitored zone to formulate and solve an evolutionary optimization problem modeling the activation of the deployed sensors. We adapt the spatial sensor distribution to the local probability...
The business of setting up automated teller machines (ATMs) for banks depends on many factors such as the price of buying or leasing an ATM, cost of deployment, cost of operation, and ATM characteristics to be deployed. ATM deployment is an intensive computational problem since it is analogous to file server placement, which is known to be as NP-complete problem. Also, ATM maintenance is an intensive...
The coverage problem in wireless sensor networks is to place sensor devices in a service area so that the entire service area is covered/sensed. We have modeled the coverage problem as two sub-problems: floorplan and placement. The floorplan problem is to partition the service area into well-defined geometric cells, whereas the placement problem is to assign the sensor devices into a set of cells...
Wireless sensor-actor networks (WSANs) refer to a group of sensors and actors linked by wireless medium to perform distributed sensing and acting tasks. The main communication paradigm in WSANs is based on the sensor-actor coordination. Appropriate actions, which are corresponding to the sensed phenomenon, can't be performed unless the event's information is transmitted from the sensors to actors...
