The Novel Positioning System based on Coverage Elimination in Wireless Sensor Networks
Wireless sensor networks have popularly applied in many fields for environmental monitoring. Positioning the
target is the critical issue in the monitoring application. Many positioning methods used for wireless communication use the
Trilateration positioning technique to locate the target. Triangulation positioning is not suitable for the sensor nodes because
the sensor nodes cannot get correct distance from received signal strength. Thus, this paper proposed a novel positioning
method named Coverage Elimination Positioning System (CEPS). The CEPS locates the area of target without using the
distance estimation but using the area elimination technique. Simulation results show that CEPS obtains higher positioning
accuracy than TP when sensor nodes are deployed densely. Furthermore, the CEPS is also better than the Angle of Arrival
(AoA) positioning method. The possible area is reducing more than 30%.
