By means of wireless communication, a master device can detect and identify nearby elec- tronic tags. Traditionally, the performance of RFID systems and their identification protocols has been analyzed for static configurations, that is, without considering incoming or outgoing tags, but just a fixed number of initially unidentified tags. However, many real scenarios cannot be consistently modeled that way. In this work we introduce a Markov model which allows us to study a dynamic RFID tag scenario, where a flow of tags is considered. This model can be used to compute the Tag Loss Ratio, which measures the ratio of outgoing unidentified tags to the incoming tags in the system, which is a critical metric in dynamic configurations. The analysis is carried out for two families of protocols used as medium access control in RFID, Framed Slotted Aloha and non-persistent CSMA. With the aim of validating the analysis predictions, we get simulation results, by means of a simulator. We evaluate a scenario similar to a real application, i.e. a mail control system based on RFID.","PeriodicalId":259055,"journal":{"name":"Int. J. RF Technol. Res.

The IoT based Railway Track Monitoring System (IoT-RMS) is proposed for monitoring the health of the railway track. The system identifies any abnormality in the tracks at an early stage. These abnormalities are rectified before they develop for smoother transportation. The micro electro mechanical system (MEMS) accelerometers are placed in the axle box for measuring the signal. It becomes hard to identify the exact location of abnormalities when the global positioning system (GPS) falters due to signalling issues. In this paper, a new hybrid method is proposed for locating irregularities on a track; even in the absence of a GPS signal. Pre-processing of the GPS signal is carried out effectively because the sensors used in IoT-RMS are capable of functioning in a high noise environment. The IoT-RMS updates the location of the abnormality in the cloud and shares it with other trains that will be passing through that location. As a result, the drivers of trains respond accordingly and avoid derailment. An experimental setup has been developed for a study of the performances for four different abnormal cases, and the result shows the effectiveness of the proposed system.","PeriodicalId":259055,"journal":{"name":"Int.

Pallets are needed in order to ship products from the produc- ers/distributors to the retailers. Recently, pilot projects have demonstrated that performances of pallet management system could be improved by an advance tracking system based on Radio Frequency IDenti- fication (RFID). RFID systems can increase effectiveness in acquiring data about properties of any entity - such as pallet - that can be physically identified and traced. In this paper, an effective model, based on the well known Activity Based Costing (ABC) technique, is proposed to evaluate economic feasibility of different design decisions regarding the whole pallet management system of a logistics provider. The model has been applied to different operational scenarios in a real case study: The scenario analysis aims to compare different configurations of pallet management systems based on RFID applications. Results obtained highlight how an RFID application is economically sustainable to reduce the overall cost of pal- let management activities in different operational conditions. Finally, based on cost structure previously evaluated by the ABC model, an investment evaluation based on traditional indexes (e.g. ROI, Net Present Value, etc.) has been carried out. Therefore, the integration of the ABC model with traditional investment analysis has improved the effectiveness and the reliability of the feasibility study for evaluating RFID investments in pallet management.","PeriodicalId":259055,"journal":{"name":"Int.
