Wireless Sensor Network For Landslide Detection

Wireless sensor networks are very important in everyday life. This new technology is exciting with unlimited potential for numerous application areas including environmental, medical, military, transportation, entertainment, emergency management and homeland defence. WSN are connected with nodes, in WSN communication takes place through air. The exploration subject that I have picked is on Wireless

With the furtherance of computer networks extending boundaries and joining distant locations, wireless sensor networks (WSN) emerged as the new frontier in developing opportunities in order to collect and process data from remote locations. A wireless sensor network is a collection of nodes organized in a cooperative manner. Multiple sensor nodes arranged in proximity to sense an event and subsequently transmit sensed and collected information to a remote processing unit or base station. The nodes are able to communicate wirelessly and often self-organize after being deployed in an ad hoc fashion. More than 1000s or even 10,000 nodes are expected. Currently, wireless sensor

A wireless sensor network (WSN) consists of distributed sensors to monitor environmental conditions such as temperature, sound, vibration, pressure, motion or detect dimensions, to pass their data through the network to a base station for processing. Advantages of WSN over a wired system considered in elimination of wiring cost, sensors can be installed in harsh environments. Each sensor node is a combination of Radio transceiver with an internal antenna or connection to an external antenna micro-controller, electronic circuit for interfacing with the sensors, energy source, usually a battery or an embedded form of energy harvesting. Drawback of using sensors is having limited power to consume, a memory that is

Radio Frequency Identification (RFID) technology is commonly used for object identification and tracking. In this study we explore the feasibility of its use in wireless monitoring of water level that will serve as an early warning system for flood occurrence. To measure the level of water, water detecting sensors monitors the signal and sends it to

Densely deployment nature of sensor nodes allows the sensor networks to keep functioning even if some of the nodes are destroyed or compromised. Therefore, there is a vast application of sensor networks especially in disastrous situations. Some of the examples of sensor network applications are:

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

Wireless Network Sensors (WSNs) [4] has offered a lot of Intelligent Systems which require minimum expenditure with least labor services. WSNs works entirely on sensors which sense physical as well as environmental conditions such as temperature, sound, pressure, noise etc. We have come along with lots and lots of services in Industrial monitoring, health care monitoring, and environmental monitoring using WSNs. I came across an interesting journal of Intelligent Parking Lot Application using Wireless Sensor Networks by Sangwon Lee, Dukhee Yoon and Amitabha Ghosh, 2008.

Due to the advancement in micro-electro-mechanical systems and microelectronics and correspondingly wide applications of wireless sensor networks, there has been given tremendous attentions by researchers in recent years. In result there is development of low-cost, low-power, multifunctional sensor nodes that are small in size and communicate untethered in short distances. These tiny sensor nodes, which consist of sensing, data processing, and communicating components, leverage the idea of sensor networks based on collaborative effort of a large number of nodes. Sensor nodes in such a network are often powered with onboard batteries with limited energy. It is impractical or infeasible to replenish energy via replacing batteries on these sensors in most applications. As a result, it is well perceived that a sensor network should be deployed with high density in order to prolong the network lifetime. A sensor network is composed of a large number of sensor nodes, which are densely deployed either inside the phenomenon or very close to it. The position of sensor nodes need not be engineered or pre-determined. This allows random deployment in inaccessible terrains or disaster relief operations. On the other hand, this also means that sensor network protocols and algorithms must possess self-organizing capabilities. Another unique feature of sensor networks is the cooperative effort of sensor nodes. Sensor nodes are fitted with an on-board processor. Instead of

processing. Sensor nodes are of very small size, consume extremely low energy, are operated in high

A wireless sensor network consists of potentially thousands of tiny wireless devices capable of taking various environmental measurements, such as temperature, humidity, vibrations, and luminance. Such immensity of sensing has been promoting a plethora of emerging applications in areas ranging from homeland security, healthcare, to the military. Sensor networks have attracted much scientific interest during the past few

The grouping of various sensor nodes makeup a huge Wireless Sensor Network (WSN). These wireless sensor networks are employed in environments where human reach is difficult. The sensor nodes are small, inexpensive, battery powered devices which are capable of local processing and wireless communication. These sensors cooperatively work with each other to sense some physical circumstances and then the information is gathered and processed to get pertinent results. The information that is gathered is sent to the main location.

A wireless sensor network (WSN) is a network consisting of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, humidity, motion or pollutants and to cooperatively pass their data through the network to a main location. The WSN is built of nodes from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensors. Each such sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting [23].

A wireless sensor network (WSN) consists of sensing device, computation element, and communication elements that gives user the ability to measure, observe and react to particular events and phenomena in that problem field. A sensing device provides data from sensing physical characteristics such as temperature, pressure and sound etc and then transmits that data to the base station via radio either on time basis or demand basis. A wireless sensor network may contains just a few or large number of wireless sensor nodes, operating in a synchronized and coherent manner to fulfill a common task depending on application.

Several million acres of forest are destroyed every year due to forest fire. Forest fire not only destroys many valuable trees but also destroys the
