Anti-Collision in WSN and RFID Network Integration

Wireless Sensor Network (WSN) and Radio Frequency Identification (RFID) systems have engrossed considerable attention in recent years for ubiquitous computing. Their use revolutionizes diverse application areas. The integration of WSN and RFID enhances the capabilities of both the technologies providing way to diverse research areas. The integrated network of WSN and RFID systems involves various challenges among which Anti collision is significant. This is because it is directly related to time delay and energy consumption and result in waste of various network resources. In this paper, Anti collision challenge is taken into consideration to improve the performance of integrated RFID sensor network. An algorithm is proposed to overcome Anti collision problem. Anti collision is discussed in detail along with its effects on system. Proposed algorithm is compared with previous available technique. The performance of Anti-collision algorithm is tested in terms of throughput and mean delay. Simulation results show that the proposed algorithm successfully achieves Anti-collision.
