Optimal Spatial Pattern for Wireless Sensor Network Based on Energy Minimization in Intelligent Transportation Systems

چکیده
Wireless Sensor Networks are proposed to improve vehicle safety to avoid collisions in congested junctions and to enhance the capability of warning systems in the event of an emergency. The critical challenge in sensor networks is the extended temporal operation of the individual sensor node using a typically limited battery power supply. The sensor node consumes power due to sensing, signal processing, embedded computing and connectivity. In this paper the spatial arrangement of the sensor nodes in a typical traffic junction will be determined. The emplacement of sensor nodes will be designed with the constraints of energy minimization and coverage area maximization. The sensor node placement techniques in WSN have been analyzed and addressed to increase the lifetime, area coverage maximization, indirect cost benefits due to reduced number of deployment of sensors due to optimal placement.
