Micro Electro Mechanical Frameworks And Low Power And Extremely Incorporated Computerized Hardware

World Wide Web). The nodes can be static or dynamic [24]. Wireless Sensor Networks (WSN) will continue to play a very important role in our day to day lives. A WSN contains of sensor nodes that are powered by little unique batteries. These sensor nodes are densely arranged in the area to be monitored to sense and transmit information towards the base station. WSN can simplify structure design and operation, as the environment being monitored does not need the communication or energy infrastructure connected with wired networks [25].

Network nodes can have logical or actual communication with all devices,this communication mostly defines the type of network topology, depending on the application. Sensors are able to be pair with all the topologies types but, in some cases, the sensors may not be appropriate for all the networks. Most logical network topology tends to be defined depending on their logical roles. Centralized configuration techniques are always appropriate for networks whereby the processing power capacity specifically depends on a specific but unique device. The device is responsible for coordination, processing, and management of any information activities that is sensed within the environment. From here, it forwards the grasped information to a sink node. This, therefore, means that the sensors are quite reliable in grasping information (Karl, Holger, and Willig 2005, 105). The advantage of this network arrangement is the centralized configuration allows more energy management and roaming is usually allowed inside the network to facilitate

Autonomous sensors nodes to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a receiver (destination) [1] [7].

Sensors (which are devices with processor, memory, storage, inputs and outputs, OS and software capabilities that gather and/or disseminate data on just about anything ), are attached to objects, and the objects’ identities, state or state of surroundings become capable of being relayed to an Internet connected IT structure. The sensors relay data to the outside world through local area and wide area, wireless or wired links. . Local, on

Sensor network got tremendous focus due to its less cost and small size and which can be placed anywhere. A sensor network consists of number of sensor nodes dispersed in a specific geographical area. These sensor nodes communicate using wireless transceivers. These networks are widely used

In our view, sensors are the “magic” of the IoT. The sensor market is enormous, with Analog Devices estimating it to approach $100 billion annually, much of which is not related to semiconductors at all. The sensor market applicable to semiconductor vendors includes micro-electromechanical systems (MEMS) - based sensors, optical sensors, ambient light sensors, gesture sensors, proximity sensors, touch sensors, fingerprint sensors and more. These chips effectively detect changes in the environment, creating the information that is ultimately transmitted via a wireless chip and interpreted through application software to create an IoT solution. Sensors or sensor networks (Smart Dust, Mesh Networks, etc.) can provide feedback about numerous

Developments in micro electro mechanical systems (MEMS) and wireless networks are opening a new domain in networking history. Sensors; often called "smart dust" are low cost small tiny devices with limited coverage, low power, smaller memory sizes and low bandwidth, will play a key role in collecting and disseminating data from the fields where ordinary networks are unreachable for various environmental and strategical reasons.

Microelectromechanical Systems (MEMS) are systems that are designed on a micro metre scale and have become more popular as the demand for devices to get smaller has increased. The main uses of these systems are for sensors, such as accelerometers and gyroscopes and other such devices like microscopy and inkjet nozzles for example. There are many materials that can be used for MEMS as the cost of the material is almost eradicated due to the micro size of the systems being produced. This brings materials such as gold, platinum and diamond can be used, as these materials have some properties which are very desirable for a MEM systems. The most common material that is currently used in MEMS is silicon and silicon based compounds as they

Ans: Wireless Sensor Network is a system with collection of sensors formulated with irregular patterns in remote areas with limited number of hardware resources.

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.

WSN can be applied to many other fields such as habitat monitoring, environment monitoring, smarthome, intelligent transportation and so on.

Fault tolerance and adaptability: Fault tolerance is the capacity to keep up sensor network functionalities with no interference because of disappointment of sensor nodes. At the point when any node falls flat adaptive convention change it to produce new connection [8].

Wireless Sensor Networks (WSN) consists of large number of sensor nodes distributed across a geographical area in highly dense manner. These nodes are of low cost and use less energy to perform various functions. These sensors have the ability to communicate with each other and route the data to next node or back to the Base Station (BS). Sensor nodes in a sensor network communicate with other nodes and collect the information.

The remote sensor system is shaped by extensive number of sensor hubs. Sensor hubs may be homogeneous or heterogeneous. These systems are exceptionally conveyed and comprise of numerous number of less cost, less power, less memory and self-sorting out sensor hubs. The sensor hubs have the capacity of detecting the temperature, weight, vibration, movement, mugginess, sound as in and so on. These sensor hubs comprises four fundamental units: detecting unit, handling unit, transmission unit, and force unit. For listening

A Wireless Sensor Network (WSN) is comprised of multiple tiny devices called nodes or motes. These are distributed spatially in an environment to monitor sense and compute data wirelessly. The role of a sensor node is to evaluate different tasks. First, a node has to sense physical conditions and exchange the information with other nodes after computation. Second, it plays the important role of being a relay for different sensor nodes [1],[2],[3],[4]. These nodes can mount anywhere in the environment [2]. With recent advancements in the field of electronics these devices are becoming cheaper and smaller and are being employed in both indoor and outdoor environments. Applications include agricultural monitoring, household and military surveillance, industrial automation and robotics, and healthcare [3]. A sensor node, shown in Figure.1 is a low power device and consists of five different components namely [5], [12]
