Benefits Over Traditional Wired Sensing Technology

A Wireless Sensor Network is one kind of wireless network includes a large number of circulating, self-directed, minute, low powered devices named sensor nodes called motes. These networks certainly cover a huge number of spatially distributed, little, battery-operated, embedded devices that are networked to caringly collect, process, and transfer data to the operators, and it has controlled the capabilities of computing & processing. Nodes are the tiny computers, which work jointly to form the networks. The sensor node is a multi-functional, energy efficient wireless device. The applications of motes in industrial are widespread. A collection of sensor nodes collects the data from the surroundings to achieve specific

In our project, we are trying to provide an embedded wireless system by using the Army base stations can monitor the health of soldiers using wireless body area sensor networks such as temperature sensor, heart beat sensor, etc. Base stations can also track the location of soldiers by using Global positioning system (GPS)

Nowadays, Wireless sensor networks (WSNs) are getting more and more involved in our society, researchers and manufacture. As the use of WSNs increases the more challenges rise to make them immune and life longer. Therefore, both fields industry and academia invest money to improve the capability of the security integrity, confidentiality, and authentication. Since WSNs are distributed in unfrequented and abandoned venues, the physical security is unconcerned or less concern. The most concern is the lifetime of Wireless sensor networks, sensors have limited source of power. Thus, economizing energy will keep sensors live longer, the less power means more efficiency. Moreover, secure data is important as well, since no one attends where sensors are located, it is easy to manipulate data or steal it. Cryptography provides high security to WSNs, using algorithms to encrypt and decrypt the sent data is

A wireless local area network (WLAN) is a wireless distribution method that uses high frequency radio waves to connect two or more gadgets. It allows users to communicate between network-enabled devices within and around the coverage area.

The mobile computing technology is an emerging technology, which consist of wireless sensor networks. The wireless sensor is the smallest unit of a network and some of the features supports large scale deployment, mobility, reliability and other applications. According to (Hoon-Jae, 2011), the main goals of WSNs are to deploy a number sensor devices over an unattended area and transmit to certain locations.

Sensor network protocols have a unique capability self-organizing. Another interesting feature of wireless sensor networks is that the sensor nodes cooperate with each other. Sensor nodes have an in-built processor, using which before transmission raw data is processed. These features facilitate wide range of applications of wireless sensor networks like biomedical, environmental, military, event detection and vehicular telematics.

Wireless sensor networks consists of large number of sensors which are distributed densely and partially. There are numerous number of small sensor nodes which are self-restrained which consists of sensors which performs according to the environmental conditions.

WSN devices can operate over a wide temperature range, are less prone to shocks and vibration, and provide safety and electromagnetic compatibility. A wireless measurement system frees you from the confines of wired infrastructure [8].

Abstract- Wireless sensor networks have many advantages over traditional wired sensing technology, due to their embedded construction. This technology has been used in agricultural scenario because of the need for enhancing precision, quality and quantity in farming. This paper is about developing a prototype for the system which utilized a real time wireless sensor network to communicate wirelessly with a pest management system that measures the various parameters like air temperature, air humidity and leaf wetness duration in an Apple and Picrorhiza Kurroa (Kutki) farm for the prediction of disease, Apple Scab in Apple and Powdery Mildew in Kutki. For this purpose an application software has been developed to derive a relation among

Wireless Sensor and Actor Networks (WSAN) have attracted a lot of interest in recent years. Their potential applications include search-and-rescue, forest fire detection and containment, battlefield reconnaissance, under-water surveillance, etc. In WSAN, sensors which are small, densely-populated, and power-constrained devices probe their surroundings and send the collected data to more capable nodes (actors) for processing and putting forward an appropriate response [1]. For example, sensors can detect rising heat in some spots in a forest and inform mobile robots (actors) that correlate the reports from various sensors and conclude the eruption

Multiple autonomous, tiny, low-cost and low-power sensor nodes comprise a wireless sensors network (WSN). The sensors nodes are equipped with various types of sensors such as thermal , acoustic, chemical, pressure, weather and optical sensors which gather information from various nodes and collaborate to forward sensed data to base stations for further processing. WSNs designers have to address common issues related to data aggregation, data reliability,

Wireless sensor nodes consists of three pars first one is wireless means without wires second one is sensor mean our nodes or data sensing process third and last one is networks means connection of these nodes to form a network to communicate and report data. When we concern its quality of service it may become too wide part of research so we are promised to work only in energy efficient protocols. The reason behind wireless

A Wireless Sensor Network can be composed of large number of tiny of sensor nodes spread in a wide area and communicating with each other either directly or through routing mechanisms to the other nodes. One or more of the nodes are the base station with uninterrupted battery source than the other nodes. Since the devices in WSN are often tiny devices with small form factor the computational power of these devices is usually small because there will not support large amount of hardware. Furthermore as the devices are wireless they need to obtain their energy from an inbuilt battery which in the end needs to be recharged or replaced. If the battery of a device is depleted it needs an immediate substitution to function further .

Wireless sensor networks are the networks that gather information such as environmental information, which there are numbers of applications of WSN such as healthcare, building monitoring, forest fire, smart home etc. WSN is capable of sensing, processing and communicating independently. However, as most of the sensor nodes are powered by non-rechargeable battery, the limitation of energy supply has considerably reduced the lifetime of the sensor network. Hence, new designs of sensor node network and energy efficient MAC (Media Access Control) and protocols for long term autonomous monitoring wireless sensor network has become the next vision.
