An innovative model that goals to design, develop and instrument by utilization of WSN modules for improved form of toll collection structure. In the proposed system when the user approaches to the payment lane, the Xbee wireless transceiver receives the signal that the automobile has arrived at the payment lane, then automatically the unique id of the passenger that is the Vehicle ID has been read via on-board unit, which will be attached to every motor vehicle and collects the day-to-day toll price for that particular route. The system is employed to every motor vehicles at the time of the registration of new vehicles or it can be attached in old vehicles. This system tends to cuts the time periods for paying the toll at faster rate rather than waiting in enormous queues. If the Vehicle crosses the toll without paying toll bill less than three times, the gasoline valve of the motor vehicle is locked using relay with the support of on-board unit.

Data aggregation is the technique used togather the sensor data to reduce the duplicate data transmission. It is an effectual approach for Wireless Sensor Networks (WSNs) to save energy and prolong network life time. Existing Reliable Spatial Window Aggregation (RESA) query processing algorithm proposed to reduce packet loss rate during data communication and balance the load of nodes. The main problem in existing system is the single node act as the cluster head at every transmission so it takes more energy than the sensor nodes and the duplicate data can be stored at the cluster head. In order to address this problem, a Pattern Based Aggregation using query processing algorithm called PBA is proposed. PBA only requires each node to maintain location of its neighbours. According to the information it divides the query area into several sub regions followed by collection of sensor readings in each sub region. It is proposed to reduce the transmission of duplicate data during communication. An Oscilloscope measurement technique is proposed to measure the energy level of the sensor node.
