Sensor network has occupied an important space in current research. Small size of the sensor nodes put constraint on the hardware capabilities and battery supported on it. In this paper, the authors have discussed threshold policy for selecting a particular state of sensor node with fixed threshold policy. Threshold policies are needed whenever to choose the better one between two or many possibilities. They investigate the dynamics on random geometric networks. Fixed threshold policy is considered that enables the sensor node to vary and continue its service so that data loss can be minimized.
