In case of no fixed infrastructure (military applications and emergency rescue operations) and we need to build a network with low cost, Wireless sensor networks (WSNs) are useful. We have no fixed routing protocol, or intrusion detection technique available for them because WSNs arc dynamic in nature and individual nodes of the network are required for this to be done. Nodes are mobile in most of the applications of WSNs, so they depend on battery power and availability of limited resources which shows that power consumption is an effective research area for performing a set of tasks in WSNs. To deal with such an issue, machine learning (ML) techniques (sell-learning algorithms, working without programming or human intervention) can be applied effectively according to the application requirement. In this paper, we have done comparative about several ML-based techniques for WSNs. In addition, we also analyzed ML techniques for clustering and energy harvesting. At the end, we present a summary of ML techniques for both clustering and energy harvesting with some open issues.

Research in the field of human machine interaction and machine learning contributed to the revival of the chatbots. They are virtual interlocutors whose logical apparatus is based on artificial intelligence. However, recent reviews show that chatbots are perceived as unwise systems. These results contributed to the rapid introduction of chatbots in social networks. At the same time, the question of choosing the structure of a neural network for learning dialogue systems, the principles and features of human machine interaction remains important. In this paper various architectures of neural networks are being compared, and it's own chatbot using encoder-decoder architecture with attention mechanism is developed. For implementation, the Python programming language is used. TensorFlow framework is used for deep learning. The simulation results confirm the effectiveness of the proposed approach to speech recognition and human machine interaction.

Vehicular edge computing (VEC) is a potential solution to meet delay-sensitive and computation-intensive vehicular applications demands. However, the nature of mobility brings a significant challenge, i.e., when and where to offload task can capture the optimal delay performance for VEC. To address this challenge, firstly, we characterizes the temporal-spatial correlation for VEC system. With the aid of this, we formulate the energy-constrainted delay minimization problem as a mixed integer nonlinear programming (MINLP). Due to the fact that it is hard to tackle the features about non-convex and coupling of designed MINLP problem, this paper transforms the original problem into task placement sub-problem and delayed offloading sub-problem. Specifically, the former is solved by two-stage decision tree algorithm and the latter is obtained by dynamic programming technique. On this basis, a temporal-spatial computation offloading scheme is proposed. Simulations demonstrate that our proposed scheme achieves superior delay performance and provides useful guides for choosing suitable schemes in different conditions.
These days, different design methodologies are proposed for actualizing various types of answers for the product wanted for complex frameworks. Among them design patterns are as often as possible used to develop the o...

network Functions Virtualization (NFV) in Software Defined networks (SDN) emerged as a new technology for creating virtual instances for smooth execution of multiple applications. Their amalgamation provides flexible and programmable platforms to utilize the network resources for providing Quality of Service (QoS) to various applications. In SDN-enabled NFV setups, the underlying network services can be viewed as a series of virtual network functions (VNFs) and their optimal deployment on physical/virtual nodes is considered a challenging task to perform. However, SDNs have evolved from single-domain to multi-domain setups in the recent era. Thus, the complexity of the underlying VNF deployment problem in multi-domain setups has increased manifold. Moreover, the energy utilization aspect is relatively unexplored with respect to an optimal mapping of VNFs across multiple SDN domains. Hence, in this work, the VNF deployment problem in multi-domain SDN setup has been addressed with a primary emphasis on reducing the overall energy consumption for deploying the maximum number of VNFs with guaranteed QoS. The problem in hand is initially formulated as a "Multi-objective Optimization Problem" based on Integer Linear programming (ILP) to obtain an optimal solution. However, the formulated ILP becomes complex to solve with an increasing number of decision variables and constraints with an increase in the size of the network. Thus, we leverage the benefits of the popular evolutionary optimization algorithms to solve the problem under consideration. In order to deduce the most appropriate evolutionary optimization algorithm to solve the considered problem, it is subjected to different variants of evolutionary algorithms on the widely used MOEA framework (an open source java framework based on multi-objective evolutionary algorithms). The experimental results demonstrate that the proposed scheme achieves better results in comparison to the epsilon-Non-dominated Sorting Genetic

Nowadays, runtime workload distribution and resource tuning for heterogeneous multicores running multiple openCL applications is still an open quest. This paper proposes an adaptive policy capable at identifying an optimal working point for an unknown multiprogrammed openCL workload without using any design-time application profiling or analysis. The approach compared against a design-time optimization strategy demonstrates to be effective in converging to an solution guaranteeing required performance while minimizing power consumption and maximum temperature;it achieves on average values 0.085 W (5.15%) and 0.83 degrees C (1.47%) worse than the static optimal solution.

In machine learning, neural networks have excelled at performing tasks at a high level with a simple and flexible implementation. Neural networks are particularly well-suited for novice programmers due to the availability of open-source libraries like TensorFlow and Caffe. However, novice programmers often neglect to learn beyond the black-box behaviors that these libraries provide. Introductory college students often lack the understanding of neural network internals, such as hidden layers and activation functions, and their interactions during training, which are crucial to efficiently solving more complex problems. Here, we present Omega(3), a device that opens up the black-box of neural networks by visually representing how hidden layers behave during training in real-time. In addition, Omega(3) provides an engaging tactile and visual educational experience to students, and waives the requirement for a strong programming background in order to learn about neural networks. In this paper, we will discuss the fabrication and set-up of Omega(3) as well as evaluate and compare Omega(3) to traditional lecture based learning.

Recent cloud technologies enable a diverse set of novel applications with capabilities never seen before. Cloud native programming, microservices, serverless architectures are novel paradigms reducing the burden on both software developers and operators while enabling cloud-grade service deployments. Several types of applications fit in well with the new concepts, however, latency sensitive applications with strict delay constraints pose additional challenges on the platforms. Can we run these applications on today's public cloud platforms making use of the brand new tools and techniques? In this paper, we try to answer this question by addressing one of the most widely used and versatile public cloud platforms, namely Amazon's AWS, and we propose a novel mechanism to optimize the software "layout" based on dynamic performance measurements. Our contribution is threefold. First, we define a combined performance and cost model on CaaS/FaaS (Container/Function as a Service) platforms, specifically for AWS, based on a comprehensive performance analysis, and we also provide an application model capturing the performance requirements. Second, we formulate an optimization problem which minimizes the deployment costs on AWS while meeting the latency constraints. A polynomial algorithm finding the optimal solution is also given. Third, we evaluate the model and the algorithm for different scenarios and investigate the performance on today's system.

Water distribution is one of the main pillars of modern society and accounts for a constant need of innovative solutions to age-old problems. There are many challenges associated to the aging infrastructure in large metropolitan areas as well as efficient operation of control structures, requiring improved decision support systems and autonomous operation based on available data. An extension of traditional methods with modern concepts is required such as using learning algorithms, smart meters and reactive programming for improving the quality of service in water distribution systems. This paper extends an IoT-based model with Deep Learning and automated test scenarios, while showing the effective application and comparison of learning techniques on experimental data in this domain. The experimental model is described from the hardware level to the IoT platform in a modern approach using the current state of software development and architectures for real-time data management.
