On GeoSensor Network optimization using a model- based approach
نویسنده
چکیده
The presented model-based approach comprises of a phenomenon model and a model of the mobile geosensor network (GSN). The phenomenon model estimates the characteristics of the observed phenomenon by means of a geostatistical approach. Based on this phenomenon model it is determined where additional information is needed. Also the limitations and constraints of the GSN are taken into account during the optimization process. Therefore, we use Hägerstrand’s time geography, which allows modeling the potential activity area of the geosensor nodes. The potential activity area of a geosensor node is the area in which it can operate. Existing optimization methods are either based on geometric considerations like coverage and exposure based approaches or communication and energy based approaches. The presented approach combines the existing technologies of kriging and time geography in order to come up with a holistic optimization method. A table top experiment proved the efficiency of the model-based approach.

متن کاملCapacity planning in the hospital queueing network with blocking: simulation-based optimization approach
Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...
متن کاملA Chance Constraint Approach to Multi Response Optimization Based on a Network Data Envelopment Analysis
In this paper, a novel approach for multi response optimization is presented. In the proposed approach, response variables in treatments combination occur with a certain probability. Moreover, we assume that each treatment has a network style. Because of the probabilistic nature of treatment combination, the proposed approach can compute the efficiency of each treatment under the desirable reli...
