Information Retrieval (IR) is a field that concerns the structure, memory, analysis, and access to pieces of information. It has a wide application in various areas like search engines, communication systems, information filtering, medical search, etc., and helps design efficient and secure applications. This area has been a surge of research from the last few years due to data mining's unparalleled success, deep learning in Read More

Background: Low-Density Parity-Check (LDPC) codes have received significant interest in a variety of communication systems due to their superior performance and reasonable decoding complexity. Methods: A novel Collection of Punctured Codes Decoding (CPCD) technique that considers a code as a collection of its punctured codes is proposed. Two forms of CPCD, serial CPCD that decodes each punctured code serially and Read More

Background: The number of elderly people is growing, and it becomes a challenge for families to safeguard their health. They are facing decline in their health and missing some of the quality of life provided to them. They are unable to control their self. They are vulnerable to fall and get in dangerous or restricted area. Aim: This study aims towards an experiment using Real-Time Location System (RTLS) via ZigBee technolog Read More

In this paper, we have proposed different deployment strategies and have applied area-wise clustering along with modified Ant Colony Optimization to minimize energy consumption. Background: Previously, some deployment strategies were used to enhance the lifetime of WSN. In our research, we have applied some novel deployment strategies like random, spiral, and S-pattern along with a novel area-wise clustering process to Read More

Aim: To design and evaluate the performance of a Grey Wolf Optimization (GWO) based wrapper feature selection applied to the Botnet malware detection system. Background: A botnet is malicious software controlled by a master and used to compromise a distributed set of systems, in turn targeting a victim. Powerful attacks like Distributed Denial of Service (DDoS) can be triggered using a botnet. With the rapid growth of th Read More

Background: In cognitive radio networks, spectrum sensing plays an important role in identifying the underutilized spectrum bands. Conventional spectrum sensing by the energy detection method uses a single detection threshold, which degrades the detection performance. Methods: Therefore double detection threshold has been proposed for spectrum sensing in the literature to improve the detection performance, b Read More

The advanced capabilities of smart mobile devices for mobile network users have led to an explosive increase in the loads of networks, mainly driven by the increasing demand for multimedia services. Content caching in users’ devices can potentially enhance both the quality of service for mobile users and network performance. Upon users’ requests and their mobility models, a network can perform proactive caching to re Read More

Aims: This study aims to propose an 8-bit differential input low-power Successi,e Approximation Register (SAR) ADC with digital error correction technique for sensing bio-potential signals in wearable and implantable devices. Background: As dynamic comparators have the advantages of full swing output, low power consumption, high speed, and high impedance at the input, they are preferably used in energy-efficient SAR AD Read More
