Wireless sensor networks have found numerous applications in realistic environments. Typically, such networks are desirable to operate in several years without human maintenance. Yet main radio components on the conventional wireless sensors quickly consume most of the limited energy in the sensors, and thus considerably constrain the sensor lifetime. Recently, many low-power wake-up radios are designed...
In today's digitized era almost all data is transferred digitally which is very easy and advantageous but it also has some shortcomings i.e. the security of this data is very important. With the advent of wireless sensor networks in military regions, security of this secret data is very crucial. So Security technique such as steganography can provide the need to be a lightweight and energy efficient...
In the near future, networked wireless devices outnumber traditional electronic appliances. Internet of Things will enable a plethora of new applications in environmental monitoring, agricultural industry, medical diagnostics, security and transportation business, in analysis of equipment performance, conditions, troubleshooting and monitoring. Nowadays, the concept of wireless sensor networks is...
As sensors based applications are deployed, security emerges as an essential requirement. One of the critical issues of wireless sensor technology is limited sensors resources including poor sensors batteries. It leads to sensor vulnerability for battery exhausting attacks. Besides, fast exhausting of sensor battery power is not only explained by intrusions. It can be explained by a random failure...
Surveillance has always been an important task for human beings either for protecting a precious asset or gathering information from the surrounding environment. However, things to be monitored are increasing with a huge rate due to the changing requirements day by day. As a result, it becomes nearly impossible for individuals to do this task manually. To be able to fulfill such requirements, Surveillance...
the wireless sensor network technology emerged in the late 1990s, since then it has spread across a wide range of potential applications to industry, science, transportation, civil infrastructure, and security. Main research efforts in the wireless sensor network field focused on achieving the desired performance requirements and reducing the energy consumption to the least possible. This survey paper...
Modern manufacturing techniques small-sized transceiver modules allow you to create a wireless sensor network (WSN), with extremely low power consumption. The main purpose of such networks is to collect wirelessly readings from multiple sensors (sensor) distributed in the space for further storage, analysis and output of control commands.
Smart grid is the future vision for supplying energy. It integrates the advances in power engineering as well as information technology and telecommunication in one cohesive network. However, this vision poses several challenges; one of the key challenges is the continuous monitoring of the state of every component (e.g. voltage, current, temperature, energy consumption, energy prices, etc.) in the...
In this study a lighting control system which is configured as a wireless sensor network is presented. The battery powered switches and relay unit are the basic components of the system. Conventionally, the communication between switches and the relay unit is implemented in a wired fashion. In this study, a wireless network has been established based on the IEEE 802.15.4 personal area network standard...
For the “Internet of Things,” wireless devices are required that have small size, long life, and long range communication capability. One technology that meets these requirements is the wide-area ubiquitous network. This paper reports the field trials conducted over three years; services were remote reading / remote control of gas meters and bicycle management (location estimation / radio reachability)...
Low cost, battery powered wireless sensors have recently become commercially available and have the potential to radically alter traditional methods of equipment monitoring in power plants. This paper reports on a research project co-sponsored by Southern Company and EPRI to demonstrate wireless sensors in a power plant environment. The designed wireless mesh sensor networks studied in this project...
We provide in this paper three algorithms that enable the sensor nodes of a wireless sensor network (WSN) to determine their location in presence of neighbor sensors that may lie about their position. Our algorithms minimize the number of trusted nodes required by regular nodes to complete their process of localization. The algorithms always work for a given number of neighbors provided that the number...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
