The channel sparsity is exploited by transforming the channel into an angular domain from the spatial domain at millimeter wave frequencies in Beamspace Multiple-Input Multiple-Output (B-MIMO) systems. Every beam in B-MIMO corresponds to an individual radio frequency (RF) chain, and thus, beam selection techniques can reduce the RF hardware complexity. RF chain limitation is needed for an ideal beamspace precodin Read More

Background and Objectives: Magnificent localization precision and low operating expenses are the main keys and essential issues to managing and operating outdoor wireless sensor networks. This work proposes a novel and rigorous efficiency localization algorithm utilizing a simplex optimization approach for node localization. This novel optimization method is a direct search approach, and is usually directed to solve Read More

Background: In this era of emerging technologies, Mobile Wireless Sensor Network (MWSN) has emerged as a powerful tool for many applications. Applications such as battlefield and traffic surveillance, agriculture and environment monitoring, smart homes and smart cities require a specific protocol to fulfill a specific purpose. WSN is composed of numerous tiny Sensor Nodes (SNs) along with one or more sinks, where sinks h Read More

Background: As the e-commerce product reviews and social media posts are increasing enormously, the size of the database for polarity/ sentiment detection is a challenging task, and again, predicting polarities associated with respect to aspect terms end to end in a sentence is a havoc in real-time applications. Human behavior is influenced by the various opinions generated in society. Public opinion influences our Read More

Aims and Background: The topology and communication links of vehicular adhoc networks, or VANETs, are always changing due to the transient nature of automobiles. VANETs are a subset of MANETs that have applications in the transportation sector, specifically in Intelligent Transportation Systems (ITS). Routing in these networks is challenging due to frequent link detachments, rapid topological changes, and high vehicle m Read More

Aims: This paper will focus on promoting the ideas of green communication. Background: Pulse Width Modulation (PWM) generator is used to control the power transfer in any communication model. It is one of the most crucial parts of an electrical circuit. Our main focus in this research work is to develop an energy and power-efficient PWM generator by using Field Programmable Gate Array (FPGA) logic to elevate green Read More
