A Survey Paper on Wireless Sensor Network

Wireless sensor network provide a new paradigm for sensing and sending information. Wireless sensor networks are used in monitoring and control applications. Current WSN typically communicate directly with a centralized controller or a satellite, thus communication between the sensor and controller is based on a single hoop. An ongoing area of research is, where WSN nodes or terminals that communicate with each other forming a multi-hop network. Such WSNs could change their topology dynamically when connectivity among the nodes varies with the time due to node mobility. The wireless sensor networks are the type of sensor networks which is used to sense the environmental conditions like temperature, pressure etc.

This article provides an overview of wireless sensor networks, their architecture, application areas, and some open research issues. This article is submitted to the G. H. Raisoni College of Engineering and Management as a part of partial fulfilment for the award of the degree of Master of Engineering in Electronics and Telecommunication (VLSI and Embedded Systems Design) of the University of Pune in the academic year 2011-2012. Wireless sensors and wireless sensor networks have recently come to the forefront of the scientific community. This results from the increasingly smaller-sized devices being engineering, enabling many applications. The use of these sensors and the possibility of organizing them into networks have revealed many research issues and have highlighted new ways to cope with specific problems. A wireless sensor network is a collection of nodes organized into a cooperative network. Each node consists of processing capability that may contain multiple types of memory (program, data and flash memories), have an RF transceiver (usually with a single omnidirectional antenna), have a power source (e.g., batteries and solar cells), and accommodate various sensors.

Distributed network of sensors form a deployable key to information with self organizing capabilities from smart environments (building, home, utilities, industrial, transportation etc). In this paper we present the vision of wireless sensor network (WSN) which enables the interconnectivity that extends the reach of cyberspace out into the physical world with the low cost, high sensing fidelity, flexibility, fault tolerance, and rapid deployment. Its highlights are remote controlling and monitoring of physical environment with small-scale energy supply, miniaturization, low-power circuit design in vast application domain. We emphasize on the issues and challenges for designing most suitable WSN.

A wireless sensor network is a type of wireless network consist a collection of tiny device called sensor node. Sensor node has a resource constraint means battery power, storage and communication capability. These sensor nodes are set with radio interface with which they communicated with one another to form a network. Wireless sensor network has very necessary application like remote has remote environmental monitoring and target tracking. The goal of our survey is to present a comprehensive review of the recent literature on various aspects of WSN and also discuss how wireless sensor network works and advantages and disadvantages over the traditional network. Wireless Sensor Networks are networks composed of a number of sensor nodes that communicate wirelessly. It's utilized over a wide range of applications.

Wireless Sensor Network has evolved from just being used in military to the new avenues of everyday usage. It is been there for quite some time now and lot of research has been carried out by academicians over the years for making it efficient. Lot of industries have also implemented it in varied forms for sensing and controlling purpose. Wireless sensor nodes forming a cluster collects data and then feeds to the base station, where it processes data and outputs the information to server. The applications of wireless sensor networks are limitless, some of those are in health industry, security, environment, industrial establishments and nuclear facilities. This paper exhibits a review on wireless sensor network.

The wireless sensor network (WSN) is a combination of sensing, computation, and communication into a single tiny device. A sensor network consists of an array of numerous sensor networks of diverse types interconnected by a wireless communication network Sensor data is shared between these sensor nodes and used as input to a distributed estimation system. The system extracts relevant information from the available data. Fundamental design objectives of sensor networks include reliability, accuracy, flexibility, cost effectiveness, and ease of deployment. Each node has at least a sensor with an embedded processor, and low power radius. It acts as information source, sensing and collecting data samples from the environment. Node can also act as information sink, receiving dynamic configuration information from other nodes or external entities. The end portion of a node can be an antenna. A chosen configuration is the microstrip structure which allows for planar circuitry to be integrated with the WSN node. WSNs use small, low-cost embedded devices for a wide range of applications. They do not rely on any pre-existing infrastructure. The WSNs need not communicate directly with the nearest high-power control tower or base station, but only with their local peers. In this paper we have discussed related to WSN,sensors, criteria to choose a sensor, classification of sensors, sensor utilization and also we have discussed about some real WSN applications with their remaining challenges.
