Abstract: The rapid increase in internet usage for the past few decades has steered to higher demand and for adequate support for the network mobility in heterogeneous networks. However, in the existing mobile IPv6 (Internet Protocol version 6) protocols such as traditional, hierarchical, proxy and related methodologies have been stated to manage the recurrent mobility of the devices in a network with the centralized feature. However, the single point of failure, route optimization, handoff latency and security threats are highly exposed when the number of mobile device increases in the centralized approach. Also, it leads to the limitation of the size …of binding information when the mobile host needs to update its place. Hence, this paper suggests a secure and optimized architecture by distributing mobility functions as distributed access points. Also, the paper addresses the prevention measures for security attacks such as false binding message, rerun and hijack. The proposed scheme is simulated and validated using network simulator and security model verifier – AVISPA. Finally, the numerical and experimental outcomes demonstrate that the proposed scheme offers a substantial diminution in the cost of the binding update, binding refresh, and packet delivery.

Abstract:  The perfect Y antenna array configuration is among the most prevalent antenna array arrangement used in radio interferometry for synthesis imaging. It is crucial to determine an antenna array configuration that could offer further higher quality radio-images. In this paper, a novel and an efficient L-band log-periodic spiral antenna array design is presented. The radio-imaging performance of the log-periodic spiral antenna array is compared and shown to outperform an equivalent perfect Y antenna array. Radio imaging performance is evaluated using the computational simulation for the proposed L-band log-periodic spiral antenna array and the equivalent perfect Y antenna array. The metric …used for evaluation is the Structural Similarity Index (SSIM) and Surface Brightness Sensitivity (SBS). The L-band log-periodic spiral antenna array was observed to have about five times higher bandwidth, 2.24 times greater sensitivity, angular resolution better by a factor of five, and 10% wider field of view than the perfect Y configuration antenna array of comparable extent. It has been analytically demonstrated that the log-periodic spiral antenna array is an optimum configuration based on Chow’ s optimization technique. The L-band log-periodic spiral antenna array has outperformed the perfect Y configuration in many different imaging aspects. Show more

Abstract:  Fuzzy measures are used for modeling interactions between a set of elements. Simplified fuzzy measures, as k -maxitive measures, were proposed in the literature for complexity and semantic considerations. In order to analyze the importance of a coalition in the fuzzy measure, the use of indices is required. This work focuses on the generalized interaction index, gindex . Its computation requires many resources in both time and space. Following the efforts to reduce the complexity of fuzzy measure identification, this work presents two algorithms to compute the gindex for k -maxitive measures. The structure of k -maxitive measures makes …possible to compute the gindex considering the coalitions at level k and, for each of them, the number of coalitions sharing the same coefficient (called inheritors). The first algorithm deals with the space complexity and the second one also optimizes the runtime by not generating, but only counting, the number of inheritors. While counting the number of descendants is easy, this is not the case for the number of inheritors due to all the inheritors of previous considered coalitions have to be taken into account. The two proposed algorithms are tested with synthetic k -maxitive measures showing that the second algorithm is around 4 times faster than the first one. Show more

Abstract: The unprecedented growth in personal, business and research data motivate the users to lease storages from multiple cloud storage providers like Amazon, Azure, etc. Selection of cost-effective cloud storage service by considering different pricing policies along with their performance characteristics is a challenging task. This research proposes a model named as OUTFIT (Optimal sUgeno Type Fuzzy Inference sysTem) an optimal data storage hosting model by suggesting an appropriate storage type based on the user demands. In the first phase, we have surveyed Amazon, Google Cloud, Azure and Rackspace cloud storage providers and consolidated the different cloud storage types supported by …them. In the second phase the cloud service providers are ranked by using Sugeno fuzzy inference system based on the user preference. The third phase designates the appropriate service that incurs minimal estimated storage usage cost. The proposed approach is able to categorize various cloud service providers with an optimal grading process by including multiple decision criteria for fine-grained storage type selection. The observed results exhibit itself as a better selection tool in comparison with its counterpart tools like Cloudorado, RightCloudz in terms of cost. Show more

Abstract:  The design of a wireless sensor network (WSN) faces many constraints. Mostly, WSN is energy constraint because the sensor nodes are battery operated. Available power expenditure in WSN largely depends on the efficient use of limited resources and appropriate routing of the data packets. The power consumption can be minimized by balancing the energy consumption between the sensor nodes and selecting the minimum power consumption route for the data packets. Clustering is one of the most effective technique that not only uniformly distributes the energy among all the sensor nodes but also play a vital role in the designing of …routing protocols. So based on these advantages, a low power consumption routing protocol is proposed that makes use of fuzzy c-means++ algorithm. The proposed approach minimizes the power consumption of the sensor network by the excellent management of the WSN and also raises the lifespan. The simulation result illustrates the effectiveness of the proposed routing method when compared with the recently developed protocols based on k-means and fuzzy c-means algorithms. Show more

Abstract: Voice User Interfaces have become popular with the advent of Alexa, Google Home, Cortana and other commercial speech recognition interfaces; however, the privacy of the end users is compromised while using these interfaces in public. In addition, users can feel a bit awkward while using these interfaces with loud voice while they are outside their homes. Contextually, ‘Hypnosis’ and ‘Hypnotherapy’ have not been frequently applied as a way of human communications although the principle of suggestion induced behavior changes in an interesting approach to interact with machines. In this paper, GEORGIE a prototype AI was used to achieve a novel …means of interaction inspired from the principles of hypnotherapy, which is a discrete interface ensuring that end-users’ privacy is not compromised. It is envisaged that people who prefer secret communication and interaction might love to use this hypnotic computer interface (hypCI). The hypCI would be the novel means of human robot interface (HRI) or human computer interface (HCI). Show more

Abstract:  Vehicular Fog Computing (VFC) is a natural extension of Fog Computing (FC) in Intelligent Transportation Systems (ITS). It is an emerging computing model that leverages latency aware and energy aware application deployment in ITS. However, due to heterogeneity, scale and dynamicity of vehicular networks (VN), deployment of VFC is a challenging task. In this paper, we propose a multi-objective optimization model towards minimizing the response time and energy consumption of VFC applications. Using the concepts of probability and queuing theory, we propose an efficient offloading scheme for the fog computing nodes (FCN) used in VFC architecture. The optimization model is …then solved using a modified differential evolution (MDE) algorithm. Extensive experimentations performed on real-world vehicular trace of Shenzhen, reveals the superiority of proposed VFC framework over generic cloud platforms. Show more

Abstract:  Intrusion detection system is a second layer of defence in a secured network environment. When comes to an IoT platform, the role of IDS is very critical since it is highly vulnerable to security threats. For a trustworthy intrusion detection system in a network, it is necessary to improve the true positives with minimum false positives. Research reveals that the true positive and false positive are conflicting objectives that are to be simultaneously optimized and hence their trade-off always exists as a major challenge. This paper presents a method to solve the tradeoff among these conflicting objectives using multi-objective particle …swarm optimization approach. We conducted empirical analysis of the system with multiple machine learning classifiers. Experimental results reveals that this technique with J48 classifier gives the highest gbest value 10.77 with minimum optimum value of false positive 0.02 and maximum true positive 0.995. Empirical evaluation shows an incredible improvement in Pareto set in the objective function space by attaining an optimum point. Show more
