Abstract:

The School of Electrical, Electronic and Computer Engineering of the North-West University is conducting research about RFID (radio frequency identification) medium range reader systems for an international company, iPico. The focus area of the present research is the development of a robust tag detection algorithm for noisy environments. During the past three years a digital detection algorithm was developed. This digital detection algorithm delivered significant improvements in detection of RFIDs over its analogue counterpart, especially in noisy environments. However, the digital detection

We proposed a two-level, master and slave, anti-collision algorithm to solve the considered problem for an optimal solution. The master problem is to determine the total number of time slots, which is delivered to the slave problem. The slave problem is to solve for the optimal time slot assignment pattern to minimize the number of reader collisions under the given total number of time slots. We use a genetic algorithm to solve the slave problem and use a bise

Abstract:

Radio frequency Identification (RFID) system is latest a technology. It has been used in various applications in the world. Radio frequency identification (RFID) can be used in supply chain management, automated payment systems and other daily application as essential technology to enhance lives of human beings. RFID systems are vulnerable for many malicious attacks against privacy and security. To solve these problems, many authentication protocols based on cryptography scheme have been developed in order to ensure preservation of privacy. However, many of the these approaches cannot fully pr

Three different sizes of reader antenna are designed and operated at RFID band. The first reader antenna uses with reflector for impedance matching, which can reduce the size by increasing meander paths. This antenna achieves the reading distance approximately 7.65 m for EIRP 1W. The second antenna sets the reflector on background that achieve to reduce the size of antenna. It also adopts the reflector structure to match the impedance. The read dista

When a reader reads the information from the tags, other near readers may be interfered in the same channel. Thus, the channel should be reallocated to avoid the interference. Moreover, in regular 2-D deployment of the readers, the channel allocation should be considered by two dimentional. Therefore, in this thesis, three reader deployment topologies, the triangular, grid and hexagonal, are investigated for the channel allocation for the readers. From the experiments,

Regarding to the privacy and security problem of tags, most schemes discuss the authentication issue between the backend system and tags. In addition, collisions may happen when tags respond to the reader simultaneously so that the reader can not identify tags correctly. There seems to be a lot of places can be improved in the present solutions. In this thesis we take into account the resource constrained of tags and propose a new way to reso

Based on the requirements of most RFID applications, reading multiple tags simultaneously by the same reader is a necessary function of a reader. This work implements a MIMO space multiple division radio frequency identification system. The system can be roughly divided into three parts. Firstly, using pseudo Doppler method technology. It estimates the incident angle of two tag signals.
