Aug 15th 2015 Radio frequency identification (RFID) and wireless sensor networks (WSN)
Radio frequency identification (RFID) systems provide a powerful technology for tracking the movement of goods throughout the supply chain. The most controversial use of RFID is RFID tags in passports. Other uses of RFID include product tracking, hospital patient identification, asset tracking and security, animal identification, automotive security, car licenses, access systems and public transport payment systems. Wireless sensor networks (WSNs) are networks of interconnected …show more content…
The Germans, Japanese, Americans and British were all using radar—which had been discovered in 1935 by Scottish physicist Sir Robert Alexander Watson-Watt—to warn of approaching planes while they were still miles away. Because of this, the capabilities of RFID have expanded exponentially. The development in RFID includes the decrease of components price, increased read ranges and accuracy, better anti-collision techniques, and increased performance in demanding and previously non-ideal environments. Much progress has been made in the last few years in creating global and industry standards for RFID, thus increasing compatibility and ROI of investments in RFID. (Jovix, …show more content…
A wireless ad hoc network is a collection of wireless nodes, which communicate directly over a common wireless channel. There is no additional infrastructure needed for ad hoc networks. Therefore, every node is equipped with a wireless transceiver and has to be able to act as a router, to process packets to their destinations. (Nack. F, n.d.)
Conclusion and Future
As a conclusion, we know that RFID and WSN are widely used in business world, they are efficient methods to monitor the status of products and One of the major advantages of RFID is that information exchange between tags and readers is rapid, automatic and does not require direct contact or line of sight.
Wireless sensor networks are used in monitoring environmental changes, traffic or military activity, protecting property, efficiently operating and managing machinery and vehicles, establishing security perimeters, monitoring supply chain management, or detecting chemical, biological, or radiological material.
