Abstract Radio Frequency Identification (RFID) is a wireless data capturing technology that provides the capability of monitoring, tracking, and identifying objects at distance using radio waves. This thesis proposes the RFID technology for the monitoring of nuclear materials during their usage, storage as a method of securing the work at nuclear facilities. While surveying the main technical challenges that oppose the deployment of RFID systems, we found that the collision problem constitutes great problem that need to be solved. We focused mainly on studying the two types of collision problem which are Tags to reader collisions and reader to reader collisions. Consequently we presented an ALOHA based anti-collision algorithm that tries solve the tags to reader collision problem. Besides, we developed three efficient optimization algorithms and validated their performance on a set of standard benchmark functions. Accordingly, we proposed the use of these three algorithms along with two other algorithms as efficient optimizers for solving the reader to reader collision problem. These algorithms are Biogeography Based Optimization (BBO), a hybrid of BBO with Simulated Annealing (SA) algorithm referred to as BBO-SA, the Adaptive hybrid of the BBO with SA algorithm known as AHBBOSA, A hybrid of Invasive Weed (IW) with the BBO named HIWBBO and A Self Learned IW-Mixed BBO (SLIWMBBO) algorithm. The proposed algorithms showed a better performance in finding the optimal distribution of RFID readers that achieve the objectives of the RFID Network Planning (RNP) problem other than the compared algorithms. The BBO and the BBO-SA are implemented on a grid based RFID network model and used for solving the RNP problem on a case study for an irradiation facility. The results of the BBO and BBO-SA encourage the improvement of the BBO-SA to the Adaptive Hybrid BBOSA (AHBBOSA) for investigating the balance of more complex objectives in large scale RNP. Subsequently, the AHBBOSA, the HIWBBO and the SLIWMBBO are used to solve the RNP problem on a continuous RFID network model. The final part of the thesis is the practical implementation of RFID based tracking system for the monitoring of nuclear materials. The presented system proves its capability of tracking nuclear materials during their usage, transportation and storage. |
