Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated with toxic chemicals. Water scarcity and water contamination has been one of the major issues faced...
In this paper, different energy harvesting solutions for an autonomous miniature wireless sensing node are invista-gated. The communication part is realized with Low Power Wide Area Network (LP-WAN) LoRa technology that combine low-power and long range capabilities. Solar, Thermal and Piezo harvesting techniques are compared for autonomous sensing application.
Localization is a very important issue to wireless sensor networks. The sensor node requires accurate location information in order to achieve the purpose of real-time monitoring and transmission of information. The more the sensor nodes and GPS modules are used in localization, the higher the localization accuracy can achieve, but employing more sensor nodes also leads to high costs. Thus, how to...
Wireless Sensors Networks (WSNs) have been gaining significant attention in both the industries and the academia in recent years. However, WSN are vulnerable to growing security threats and attacks which are inept for the current traditional security mechanisms to cope with or mitigate such security challenges. As a solution, Software Defined Network (SDN) has emerged and been merged with WSN to form...
Air and Water are the most important resources of the planet that we use daily for sustaining life. Air quality affects all living creatures, from trees and plants to animals and people. Air quality, especially in the trend of more industrialized cities and with a rapid growing population of cars, is degrading. Continuous monitoring allows the national administrations to take measures in order to...
Enormous amounts of data are growing because of the continuous and increasing use of smart devices which connect, collect, exchange and transfer these large amounts of data. With the convergence of new technologies like Internet of Things (IoT), Wireless Sensor Networks (WSNs), and Cloud Computing (CC) many sectors are benefited. Our research has to do with Big Data Delivery over the IoT. Specifically,...
Energy Neutral Operation (ENO) has created the ability to continuously operate wireless sensor networks in areas such as environmental monitoring, hazard detection and industrial IoT applications. Current ENO approaches utilise techniques such as sample rate control, adaptive duty cycling and data reduction methods to balance energy generation, storage and consumption. However, the state of the art...
A Wireless Sensor Network (WSN) is a network of thousands of low-cost sensors which have a limited operating lifetime. A sensor node generally comprises four basic elements, including a transceiver unit, a detection unit, a processing unit, and an energy supply unit. One of the major challenges in the WSN is to increase the network life-time. Since the transmitting/receiving unit has the highest energy...
Existing wireless sensor network are developing rapidly and soon will occupy a dominant place among the data collection and communication. The remote location of the sensors and automatic operation increases their vulnerability to outside intrusions and attacks. Because of out of constant sensor supply the providing of authentication is quite challenging whereas the best protocols is negotiated sensor...
Due to advancement within the telecommunication, wireless communication, wireless sensors, and different technologies a replacement field of analysis has been evolved and this space of analysis is termed as Wireless Body space Networks. In WBAN miniaturized device nodes are planted within the blood stream or on the flesh. These device nodes are battery dependent, once the battery dies, node additionally...
The Internet of Things (IoT) consists of all kinds of sensors which collect much information. The privacy and anonymity in IoT is fundamental to the system and must be resolved. Sima proposed a protocol about lightweight authentication and key agreement and claimed to be secure and robust against all existing methods of attack. In this paper, the author points out the vulnerability of Sima's protocol...
The Internet of Things (IoT) paradigm, supported by the operation of wireless sensor networks (WSNs), has gained a great attention lately and new security concerns and challenges are emerging from its usage. The rising number of cyber threats makes the quest for solutions to promote resilient operations a necessity. A major threat that continues to concern the research community is a denial of service...
The role of energy in wireless sensor networks (WSN) becomes very important when network is unattended and it is not possible to recharge sensor node's battery in the sensing region many times. Due to this limited battery energy of sensor nodes it becomes a challenge for WSN to maintain proper functioning for a long time. So for the enhancement in network lifetime of the WSN, here we propose a modified...
With the rapid development of Smart Grid, urban distribution networks have greatly expanded, in which power cables have been widely used in many countries. Monitoring of power cables will increase reliability of supply and the integrity of the transmission system. Wireless Sensors Nodes (WSNs) are independent sensors which can sense and monitor certain parameters including temperature, humidity, load...
There are two main stages in the proposed system: Firstly includes detection and determining the number of evil paths depending on encoding an input messages by the source node by using the system of linear equations and sent these coded messages to the sink mode along the disjointed-multi-paths of the network. The sink node will construct number of equations from the received coded messages. It can...
Due to the peculiarity of wireless sensor networks (WSNs), where a group of sensors continuously transmit data to other sensors or to the fusion center, it is crucial to compress the transmitted data in order to save the consumed power, which is paramount in the case of portable devices. There exists several techniques for data compression such as discrete wavelet transform (DWT) based, which fails...
