Image Retrieval System Based on Perceptual Browsing Component Using Interactive Genetic Algorithm

Abstract: The most recent upgrades in digital imaging and computing innovation brought on a quick development of advanced media in the individualized computing and media outlet. Moreover, vast accumulations of such information as of now exist in various logical application spaces, for example medical imaging and geographical information system (GIS). Overseeing expansive accumulations of multimedia information require the advancement of new tools and technologies. A system for retrieving images PC framework for surfing, testing and recuperating images from substantial databases that are used to store and manage digital images. Keeping in mind the end goal to surge in the rightness of image retrieval, the descriptor contains a perceptual browsing component (PBC) which is realized by employing an algorithm based on GA which is interactive in nature and is advertised. PBC system contains color, edge, and texture as primitive low-level image descriptors. The proposed system does the recovery mechanism in two phases. In the first phase, query image is considered for getting feature descriptors and they are taken out. Thus, it is further used to compare against the images available within the database. In the development stage, highly relevant images are identified and arranged. Thus, the proposed GA-based approach can provide close results to users. The experimental evaluation is made using a database of color images which is named UCI dataset. The empirical results revealed that the proposed system is used in retrieving highly relevant images.

Elegant Energy Competent Lighting in Green Buildings Based on Energetic Power Control Using IoT Design

Abstract: Green building is a critical research zone in IoT. The energy productivity in green structures is a key for worldwide supportability. However, many elements influence energy utilization by the gadget and a large portion of the green structures are not by any stretch of the imagination green because of static energy supply and concentrated control on gadgets. Here, we propose a plan utilizing LEDs to influence utilization of dynamic energy to supply to build energy proficiency and circulated bunching of gadgets for shrewd programmed control.

Performance Optimization of LANMAR Routing Protocol in Mobile Ad Hoc Network Using DoE

Abstract: A MANET is a team of remote versatile devices or nodes that structure a system to trade data even with the lack of permanent network infrastructure. All the nodes work with the help of battery power. The efficient energy consumption is a main challenge in MANET which indeed affects the operational life of a MANET. So, the aim of this paper is to discover the most significant factor that is responsible for high energy consumption. The routing protocols’ performance is examined using simulation where one-factor-at-a-time (OFAT) approach is promoted. But, in reality, multiple factors affect the performance. But, design of experiments (DOE) approach lets many input factors to be experimented and tested in parallel that affect required output (response). This paper highlights the benefits of using Taguchi design of experiments approach to optimize the Landmark Routing Protocol in MANETs in terms of total energy consumption, control overhead and throughput. MANETs perform subjective to the design of the routing protocols and its configurable parametric values. The specific required network scenarios are simulated using EXata simulator/emulator. To recognize the most significant factor that affects the responses, Analysis of Variance (ANOVA) is applied, and the possible best factor-level combination is found using the signal-to-noise ratio analysis. ANOVA highlighted that the fisheye scope followed by fisheye update interval has the greatest impact on the responses. Later, by fine-tuning the most significant factor in the dynamic network environment, it is observed that LANMAR Routing Protocol performed better.
