Abstract: Wireless Sensor Network (WSN) contains many low cost and low power sensor nodes (SNs), these nodes may fail to communicate with each other according to some reasons such as battery lifetime, uncontrolled events or any surrounding environment actions which will lead to partition the network and reduce the Quality of Service (QoS) as well as the reliability and efficiency of the whole network. The motivation of this work was detecting these malfunctions using three approaches considered with two proposed network models : random distributed SNs and real model.Firstly, localization approach in WSN are discussed and verified using four classic localization methods to detect any failed SN, which are : Distance Vector (DV - Hop), Angle of Arrival (AoA), Time of Arrival (ToA) and Received Signal Strength Indicator (RSSI). These methods are analyzed and implemented for three different areas, each with three different numbers of SNs. All of them are implemented using MATLAB programming language. Secondly a known fault detection method called Distributed Fault Detection (DFD) discussed and implemented using MATLAB also, and a new method developed from this method named (MDFD) to overcome the disadvantages of DFD method. Finally the feature of the connectivity of the SNs themselves within the network is exploited by using two Medium Access Control (MAC) protocol standards : Sleep Medium Access Control (SMAC) and Tune Medium Access Control (TMAC) protocols, then proposed a modified MAC protocol (MMAC) to enhance the most affecting factors of these two MAC standards such as energy consumption and latency. The performance analysis of these three MAC protocols is verified and simulated using a real model for Iraq, Baghdad, Al - Kadhumyah City, by Castalia 3.2 simulator also designed and implemented these three protocols using an iOS application by the XCode program for general application sensors especially for explosives detection sensors, Fido® X3 sensor proposed forthis application. Simulation results showed that the localization methods proved their ability to localize the failed SNs, but with impractical errors (about 23%) in results than the other approaches, and additional load effect on the network due to execute the localization programs separately before each node failure detection. The DFD approach applied with homogeneous WSNs only that contain only one type of sensors, its errors (starting from 25% for three SNs) was due to its algorithm limitations in using only half of the neighbor SNs, reduced in MDFD method algorithm in which all neighbor SNs considered to detect the failed SN reaching full detection accuracy but with latency tradeoff. The MAC approach is better than localization approach because there is no need to additional hardware for node failure detection; it is also better than DFD approach because it was applicable with both homogeneous and nonhomogeneous WSNs. The three MAC protocols succeeded to detect the failed SNs, but SMAC and TMAC had their tradeoff in energy consumption and latency, when SMAC had less energy consumption (69.62% than TMAC), while TMAC had less latency (27.58% than SMAC). MMAC is combining the advantages of both SMAC and TMAC that had a less energy consumption than that in SMAC by 54.16% and smaller latency than that in TMAC by 76.19% within a range of division index m : between 1 to 5.

Abstract: The routing protocol designed for Internet of Things (IoT) systems has to be adapted with different applications requirements in order to enhance the performance of IoT applications. Therefore, the main objective of this thesis is proposing a routing protocol for wireless sensor network employed to serve IoT systems. A new IoT architecture was proposed with explaining the main functions of each layer forming the proposed architecture. The proposed routing protocol acted according to the tasks specified in this architecture. In addition, an IoT application was proposed to be applicable in some utility organizations. The link quality, node depth and energy were used as metrics to make routing decisions. In this work, different cases were proposed to exhibit the usage of these metrics and show the differences of using each of them, then examine different techniques which deal with link quality and the difference between using node - to - node link quality and end - to - end link quality. Improvements were added to the proposed routing protocol to achieve the perfect integration with suitable Media Access Control (MAC) protocol with taking into consideration the behavior of IoT application. Regarding this orientation, two approaches were suggested; the first includes the proposed routing protocol, application with high data rate and MAC protocol without sleeping capabilities; while the second approach included the proposed routing protocol, application with dynamic data rate and MAC protocol with sleeping capabilities. Comparison with other protocols was essential to show the improvements achieved by this work, thus protocols designed to serve the same purpose such as AODV, REL and LABILE were chosen to compare the proposed routing protocol with. To add integrative and holistic, some of important features such as actuating and mobility were added and tested. These features were greatly required by some of IoT applications and improving the routing protocol to support them made it more suitable for IoT systems. The proposed routing protocol was simulated using Castalia - 3.2 and all proposed approaches were examined to show the enhancement achieved by each approach. The results showed better performance when using end - to - end link quality. The results also showed the effect of MAC protocol if decreasing energy consumption was required. Sleeping MAC was the best choice when used with the proposed routing protocol while reducing the data rate. The proposed routing showed better performance than other protocols did regarding Packet Delivery Ratio (PDR) and latency. It preserved network reliability since it did not generate routing or data packets needlessly. Routing protocol with added features (actuating and mobility) showed good performance. But that performance was affected by increasing the speed of mobile nodes.

Abstract: This study focused on designing and analyzing patch antennabased metamaterial with the aid of partial ground plane. High Frequency Structure Simulation (HFSS) software was used to build and analyze a proposed unit cell of 4×4 mm² and resonant frequency of around 12 GHz. The unit cell was constructed from a patterned patch and ground plane that are connected with via through an FR - 4 substrate. The unit cell performances were studied in terms of S - parameters, effective refractive index, and dispersion properties. And it was found that the metamaterial properties appeared in the frequency band from 11 GHz to 14 GHz, where the unit cell exhibited less than 1 refractive index. A theoretical investigation based on TLM was developed to extract the values of thebasic lumped, RLC, elements network. It was found that the proposed unit cell behave like an unbalanced case of a passive constant k band elimination filter in the mentioned earlier frequency band. A parametric study based on numerical simulation was invoked to arrive to the optimal design through monitoring the effects of adding the MTM structures on the antenna performance. Therefore, this parametric study was optimized to achieve maximum bandwidth with relatively best gain.Finally, the optimal design was fabricated, measured and compared with the numerical results, obtained from Computer Simulation Technology (CST) and HFSS, in term of radiation pattern, S11 spectrum and gain. The experimental results confirmed that the gain of the antenna was 5.8 dBi at 10 GHZ with excellent matching over a wide range of frequencies. Furthermore, acceptable agreement was achieved between measured and simulated results in terms of S11 spectrum and radiation patterns at 10 GHz.

Abstract: Optical antennas, resonant structures, which efficiently collect free - space light and focus it into a nanoscale volume using plasmonic, are indispensable in the burgeoning field of nanophotonics. In this work, resonance behaviors of the fundamental resonance mode of diabolo gold metal bar optical antennas were investigated. The relationship between the near - field enhancement, absorption, and scattering spectra of localized plasmonic elements was explored. It was found that as the waist of the diabolo gold metal bar optical antenna was reduced, optical energy absorption cross section and near field enhancement at resonance increased significantly. Also reduction of the diabolo waist width caused redshift of the resonant wavelengths in the spectra of absorption cross - section, scattering cross - section, and the near electric field. Oppositely, it was found that as the length of the diabolo gold metal bar optical antenna was reduced, optical energy absorption cross section and near field enhancement at resonance decreases significantly. Also reduction of the diabolo length caused blue - shift of the resonant wavelengths in the spectra of absorption cross - section, scattering cross - section, and the near electric field.Grating surface diabolo antenna design was proposed. It was found that grating superstructure perturbed the optical properties of SPPs (Surface Plasmon polarions) and enabled the control of resonance wavelength of the antenna. The grating reduced the power that flow out from the antenna and enhanced the localized electromagnetic fields intensity. The grating also increased surface plasmon currents because of the formation of bound surface states. As a result, the absorption spectra and near field intensity were enhanced but at the same time, the scattering spectra and the far field pattern were reduced.Titanium - Gold grating surface diabolo antenna was proposed. It was found that titanium metal strengthen the grating perturbation of the optical properties of SPPs and allowed wide range of wavelength shifting (3.5 ?m). Because Gold and Titanium have difference electrical resonance characteristics, less plasmon damping occurred, resulting in lower scattering efficiency and narrower plasmon line widths.Finally, system modelling and simulations is done by using electrical department super computer (24 parallel MP and 64 GB RAM) and COMSOL multiphysics 4.4 software.

Abstract: Load forecasting is used by participants in electric energy generation, transmission, distribution, and marketing for a variety of decision - making processes, such as economic dispatch, unit commitment, hydro - thermal coordination, transaction evaluation, and expansion planning. However, the need for accurate forecasts has intensified in the last decade due to the energy industry deregulation. Taking this into account as well as the rapid fluctuations in demand and abrupt changes in weather condition, access to reliable models for accurate forecast of load demand is essential. Due to the need for accurate load forecasts, numerous statistical and artificial intelligence methods have been proposed for the short - term load forecasting problem.In this study, the Multiple Linear Regression (MLR) method, which is one of the statistical methods, and an Interval Type - 2 Takagi - Sugeno - Kang Fuzzy Logic System (IT - 2 TSK FLS), which is one of the artificial methods and an extension of the conventional fuzzy logic system, were applied. Developed models were trained using the genetic algorithm. With the purpose of an objective assessment, the available dataset was split into training samples (80%, ????????????) and test samples (20%, ??????????). The training data used in this study covered the period from January 1, 2012 to February 1, 2012 for winter season and the period from July 1, 2012 to August 1, 2012 for summer season. The actual load forecasting period started from January 22, till 28, 2012 for winter model and from July 22 till 28, 2012 for summer model.This work suggested two models; the first model was for hourly (24 hour) load forecasting for one day ahead and the second model was for one week ahead in hourly forecasting (from one until 168 hour). For each model, winter and summer seasons were presented. The Main average percentage error (MAPE) term is an index that provides information about the bias of the model and how close forecasts or predictions are to the eventual outcomes. Experiments conducted with real datasets for the Iraqi power system showed that IT2 TSK FLS models precisely approximated future load demands with an acceptable accuracy.The real data for Iraqi power system were taken from Iraqi Operation and Control Office which belongs to the Ministry of Electricity.A computer program, written in MATLAB programming languages, was developed to represent the proposed method.
