Introduction: Fault tolerance is an important issue for assuring data reliability, energy saving and prolonging the lifetime of wireless sensor networks. Since, sensor node, relay node, etc. are prone to failure, there is a need for an effective fault tolerance mechanism. Methods: Relay nodes are used as cluster heads and the concept of two disjoint paths is employed for proving fault tolerance against link failure. To eval Read More

Introduction: Web analytics is the process of examining websites to uncover patterns, correlations, trends, insights, and other useful information that can be utilized to optimize web usage and improve the quality of the website. Methods: This research proffers an approach which associates the website assessment with user satisfaction and acceptance. The proposed WQA (Website Quality Analytic) Model considers websites f Read More

Objective: With the establishment of virtualized datacenters on a large scale, cuttingedge technology requires more energy to deliver the services 24*7 hours. With this expansion and accumulation of information on a massive scale on data centers, the consumption of an excessive amount of power results in high operational costs. Therefore, there is an urgent need to make the environment more adaptive and dynamic, wher Read More

Background: Due to enormous data on web sites, recommending users for every item is impossible. For this problem, Recommender Systems (RS) are introduced. RS is categorized into Content-Based (CB), Collaborative Filtering (CF) and Hybrid RS. Based on these techniques, recommendations are made to the user. In this, CF is the recent technique used in RS in which tagging features also provided. Objective: Three main issues Read More

Background: With the availability of multiple options in wireless network simultaneously, Always Best Connected (ABC) requires dynamic selection of the best network and access technologies. Objective: In this paper, a novel dynamic access network selection algorithm based on the real time is proposed. The Available BandWidth (ABW) of each network is required to be estimated to solve the network selection problem. Methods: Read More

Background: The green Information and Communications Technologies (ICTs) have brought a revolution in uplifting the technology efficiently to facilitate the human sector in the best possible way. Green Wireless Sensor Network (WSN) tactically focuses on improving the survival period of deployed nodes (as they have a limited battery) in any target area. Objective: To address this concern, the main objective is to improve t Read More

Background & Objective: Wireless sensor networks are made up of a huge amount of less powered small sensor nodes that can audit the surroundings, collect meaningful data, and send it to the base station. Various energy management plans that pursue to lengthen the endurance of overall network have been proposed over the years, but energy conservation remains the major challenge as the sensor nodes have fini Read More

Background: Software industries are growing very fast to develop new solutions and ease people’s life. Software reliability has been considered as a critical factor in today’s growing digital world. Software reliability models are one of the most generally used mathematical tools for estimation of software reliability. These reliability models can be applied on the development of sustainable and green computing-based software’s ha Read More

Background: Planning and development of urban areas to meet the human developmental requirements is an ongoing process across the globe. This, in turn, requires continuous mapping of urban developmental patterns. Remote sensing and image processing techniques have greatly facilitated the study of urban developmental patterns by mapping urban areas. Objective: The objective of the paper is to carry out the Read More

Background: An information gathering is a typical and important task in agriculture monitoring and military surveillance. In these applications, minimization of energy consumption and maximization of network lifetime have prime importance for green computing. As wireless sensor networks comprise of a large number of sensors with limited battery power and deployed at remote geographical locations for monitori Read More

Background: Nowadays, the digital world is rising rapidly and becoming very difficult in nature's quantity, diversity, and speed. Recently, there have been two major changes in data management, which are NoSQL databases and Big Data Analytics. While evolving with the diverse reasons, their independent growths balance each other and their convergence would greatly benefit organization to make decisions on-time with the a Read More

Background: Mobile Ad-hoc network is a set of devices which are capable of communicating with each other without the help of any central entity or fixed infrastructure. The absence of fixed access points makes MANET flexible and deployable at the extreme geographical territories. Each device has routing capabilities to facilitate communication among nodes in the network. Objectives: 1) To selects the stable path which h Read More

Background: Cloud computing is characterized as the arrangement of assets or accessible administrations by the cloud service providers through web to their clients. It communicates everything as administrations over the web as per the client request, for example, the operating system, organization of equipment, storage, assets, and software. Nowadays, Intrusion Detection Systems (IDS) play a powerful role while worki Read More

In recent years, a large number of populations are dependent on mobile database technology and it is difficult for us to imagine our lifestyle in absence of database. Today’s portable handy mobile devices take part in emerging new technology for sharing distributed applications or/ and information between many users even on the move (from one network to another). To manage this resulting large Volume of data in a Read More

Agile methodology promotes changing requirements and its journey has come a long way in the software industries giving edge as well as dimensions to software products. According to the statistics, agile methodology is more successful than traditional projects. The agile team manages the project more efficiently and delivers quality product. In agile methodology, customer satisfaction is a priority due to rapid Read More

Background: Millimeter wave technology is the emerging technology in wireless communication due to increased demand for data traffic and its numerous advantages however it suffers from severe attenuation. To mitigate this attenuation, phased antenna arrays are used for unidirectional power distribution. An initial access is needed to make a connection between the base station and users in millimeter wave system. The Read More
