Spider monkey optimization algorithm is recently developed natureinspired algorithm. It is based on fission-fusion social structure of spider monkeys. Perturbation rate is one of the important parameter of spider monkey optimization algorithm, which affects the convergence behavior of spider monkey optimization algorithm. Generally, perturbation rate is a linearly increasing function. However, due to the availability of non-linearity in different applications, a non-linear function may affect the performance of spider monkey optimization algorithm. This paper provides a detailed study on various perturbation techniques used in spider monkey optimization algorithm and recommends a novel alternative of hyperbolic spider monkey optimization algorithm. The new approach is named as hyperbolic Spider Monkey Optimization algorithm as the perturbation strategy inspired by hyperbolic growth function. The proposed algorithm is tested over a set of 23 CEC 2005 benchmark problems. The experimental outcomes illustrate that the hyperbolic spider monkey optimization algorithm effectively increase the reliability of spider monkey optimization algorithm in comparison to the considered approaches. The hyperbolic spider monkey optimization algorithm provides improved perturbation rate, desirable convergence precision, rapid convergence rate, and improved global search capability.

Recently, segmentation of iris image is the most important process in a robust iris recognition system due to the images captured from non-cooperative environments which introduce occlusions, blur, specular reflections, and off-axis. However, several techniques are developed to overcome these drawbacks in the iris segmentation process; it is still a challenging task to localize the iris texture regions. In this research, an effective two-stage of iris segmentation technique is proposed in a non-cooperative environment. At first, modified Geodesic Active Contour-based level set segmentation with Particle Swarm Optimization (PSO) is employed for iris segmentation. In this, the PSO algorithm is used to minimize the energy of the gradient descent equation in a region-based level set segmentation algorithm. Then, the global threshold-based segmentation is employed for pupil region segmentation. The experiment considered two well-known databases such as UBIRIS.V1 and UBIRIS.V2. The simulation outcomes demonstrate that the proposed novel approach attained more accurate and robust iris segmentation under non-cooperative conditions. Also, the results of the modified Geodesic Active Contour-based level set segmentation with the PSO algorithm attained better results than the conventional segmentation techniques.

The data proliferation has been resulted in large-scale, high dimensional data and brings new challenges for feature selection in handwriting recognition problems. The practical challenges like the large variability and ambiguities present in the individual’s handwriting style demand an optimal feature selection algorithm that would be capable to enhance the recognition accuracy of handwriting recognition system with reduced training efforts and computational cost. This paper gives emphasis on the feature selection process and proposed a genetic algorithm based feature selection technique for handwritten digit recognition. A hybrid feature set of statistical and geometrical features is developed in order to get the effective feature set consist of local and global characteristics of sample digits. The method utilizes a genetic algorithm based feature selection for selecting best distinguishable features and k-nearest neighbour for evaluating the fitness of features of handwritten digit dataset. The experiments are carried out on standard The Chars74K handwritten digit dataset and reported a 66% reduction in the original feature set without sacrificing the recognition accuracy. The experiment results show the effectiveness of the proposed approach.

The abundant use of personal vehicles has raised the challenge of parking the vehicle in crowded places such as shopping malls. To help the driver with efficient and troublefree parking, a smart and innovative parking assistance system is required. In addition to discussing the basics of smart parking, Internet of Things (IoT), Cloud computing, and Fog computing, this chapter proposes an IoT-based smart parking system for shopping malls. To process the IoT data, a hybrid Fog architecture is adopted in order to reduce the latency, where the Fog nodes are connected across the hierarchy. The advantages of this auxiliary connection are discussed critically by comparing with other Fog architectures (hierarchical and P2P). An algorithm is defined to support the proposed architecture and is implemented on two real- world use-cases having requirements of identifying the nearest free car parking slot. The implementation is simulated for a single mall scenario as well as for a campus with multiple malls with parking areas spread across them. The simulation results have proved that our proposed architecture shows lower latency as compared to the traditional smart parking systems that use Cloud architecture. The hybrid Fog architecture minimizes communication latency significantly. Hence, the proposed architecture can suitably be applied for other IoT-based real-time applications.

Cloud computing is used to deliver IT resources over the internet. Due to the popularity of cloud computing, nowadays, most of the scientific workflows are shifted towards this environment. Many algorithms have been proposed in the literature to schedule scientific workflows in the cloud, but their execution cost is very high as they are not meeting the user-defined deadline constraint. This paper focuses on satisfying the user-defined deadline of a scientific workflow while minimizing the total execution cost. So, to achieve this, we proposed a Cost-Effective under Deadline (CEuD) constraint workflow scheduling algorithm. The proposed CEuD algorithm considers all the essential features of the Cloud and resolves the major issues such as performance variation and acquisition delay. We compared the proposed CEuD algorithm with the existing literature algorithms for scientific workflows (i.e., Montage, Epigenomics, and CyberShake) and obtained better results for minimizing the overall execution cost of the workflow while satisfying the user-defined deadline.

In today’s world it is highly difficult to manage the smart things and fulfill the communication needs without the Internet as it provides ultimate means for human to human (H2H) communication. The ‘things’ could be entities or devices that contribute for the communication. But to enhance and improve such smart communication among the things that involves nonhuman intervention, there is a need to add few more smart capabilities to the Internet. As the world of Internet is on its way of transformation into a new smart world called ‘Internet of Things’ (IoT) where the things should possess the ability of sensing, communication and control to let the things exchange information without complete intervention of humans to provide advanced and qualitative services, which is possible with the help of protocols. This paper discusses how the transition could be started and being progressed in wired and wireless systems, and how it changes the traditional means of communication among different devices and humans into a smart way. Transition here refers to how isolated things are being intermingled with each other to generate a smart protocol communication. The aim of such transition is to improve the efficiency, flexibility, adaptability and interoperability. This paper also explores various factors that contribute to IoT.

The design of efficient and fast controller for controlling the process parameter is always a challenging work to the control system designer. The main objective of this article is to design a secure chaos based controller by synchronizing two chaotic systems. The initial values of the chaotic systems are considered as the set value and initial process value of the physical parameter to be controlled. The proposed design of the controlled is done by synchronizing two-dimensional chaotic Henon map through nonlinear control method. One map is taken as a driver system and its initial value is considered as the set value of a specific process of a given system. On the other hand, another identical map is taken as the driven system and its initial value is the initial process value of the given process control system. Both the chaotic map become synchronized via nonlinear control law. The accumulation of error until synchronization is achieved which is converted into a suitable signal to operate the final control element to enhance or decrease the initial process value towards the set value. This self-repetitive process will achieve the control of the process parameter. In experiment we have observer that the error signal becomes zero after a small time interval (in simulation it takes only few iteration) and the accumulated error remain fixed in a steady value. This error is responsible to maintain the process value to the set value. The entire process has been implemented in hardware environment by using microcontroller ATMEGA 16 and also in the Proteus simulation software. The controller is very fast because the algorithm of nonlinear control law for synchronization is very fast. Since the controller is designed in chaotic regime so it is secure.
