Recent trend in wireless sensor network and its applications: a survey

Abstract

Purpose – This paper aims to review existing wireless sensor network (WSN) setups in various domains, focusing on affordable WSN so that it can be effectively utilised in solving the environmental problems. WSN is being explored in many applications such as home security, smart spaces, environmental monitoring, battlefield surveillance and target tracking. WSN consists of a number of tiny, low-powered, energy-constrained sensor nodes with sensing, data processing and wireless communication components. Creating a WSN setup will make the monitoring system effective and in future, it will give a roadmap for solving some common societal problems. Design/methodology/approach – Various research papers in the area of WSN have been reviewed on the basis of technologies and application on different fields. Findings – WSN was found to be the most effective solution in areas which are less explored due their hazardous nature and are difficult to reach. Originality/value – This review is based on research papers available and a recent trend in the area of WSN has been explored.

Low-Cost Environmental Sensor Networks: Recent Advances and Future Directions

“…In recent years there has been a marked increase in the use of low-cost sensor networks (LCSNs) in the environmental sciences to address both pure research questions and applied management issues (Benedetti et al, 2010;Ojha et al, 2015;Prasad, 2015). As sensor networks with low-cost components in the setup, the rise of LCSNs has been driven by a number of factors including: the reduced cost of microcontrollers, communication modules and environmental sensors (Fisher et al, 2015), and the open science movement, which has seen the research community readily sharing designs, underlying software and firmware and data (Pearce, 2013).…”

Decision-making in cold chain logistics using data analytics: a literature review

“…Besides WSN, they have also used data loggers as temperature sensors. In general, WSN have been used in agri-food sector for: environmental monitoring, precision agriculture, cold chain control and traceability(Prasad, 2015) Pang et al (2015). propose a procedure to derive sensor portfolios related to shelf-life prediction, precision agriculture, and sales premium (providing consumers with records of handling and environmental conditions).…”

A survey on packet size optimization for terrestrial, underwater, underground, and body area sensor networks

“…Authors compare the performance of Xlayer with current layered protocols in the literature. On the physical layer, authors investigate 2 modulation/FEC combinations (ie, BPSK or BFSK modulations/no FEC or BCH [63,57,1]) to determine the amount of energy consumed for a successfully decoded payload bit. Authors reveal that proposed framework performs better for short transmission distances.…”
