In addition, we analyze the advantage of WSN in those regions. Finally, we summarize the main parameter that affects the packages of wireless sensor network.

In this research work, a survey on Wireless Sensor Networks (WSN) and their technologies, standards and applications was carried out. Wireless sensor networks consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have b een s pecifically designed f or W SNs w here energy awareness is an essential design issue. Routing protocols in WSNs might differ depending on the application and network architecture. A multidisciplinary research area such as wireless sensor networks, where close collaboration between users, application domain experts, hardware designers, and software developers is needed to implement efficient systems. The flexibility, fault tolerance, high sensing fidelity, low cost, and rapid deployment characteristics of sensor networks create many new and exciting application areas for remote sensing. In the future, this wide range of application areas will make sensor networks an integral part of our lives. However, realization of sensor networks needs to satisfy the constraints introduced by factors such as f ault t olerance, s calability, c ost, hardware, topology change, environment, and power consumption.

A wireless sensor network is type of wireless network. Basically it consist a collection of tiny device are 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 WSNs.And also discuss how wireless sensor network works and advantages and disadvantages over the traditional network

The field of mobile and wireless communications is currently one of the fastest growing segments of the telecommunications industry. Until a few years ago, the popularity of such systems was mainly due to their ability to offer voice communications to mobile users. However, the current trend towards wireless technology is having a significant impact on the world of wireless communication networks. The movement toward integration of wireless networks and the Internet has resulted in significant change for the wireless industry. The implementation of wireless sensor networks in real life problem solving areas like traffic monitoring, patient monitoring, battlefield surveillance, and electrical power systems monitoring has helped improve on technological advancement. These wireless sensors are very small in size and are operated at low power for low data rate applications. The low-cost nature of WSNs has created tremendous advantages over the traditional communication technologies. It has been recognised as a promising technology. This paper aims at reporting an initial introduction of WSN, WSN architecture, attacks, applications, challenges and security threats.

Wireless Sensor Network over the years have become one of the most promising networking solutions with exciting new application for the near, future. Its deployment has been enhanced by its small, expensive and smart sensor nodes, which are easily deployed, depending on its application and coverage area. In this paper we focus on the Common to special application of wireless sensor network in various domain uses for military operation, monitoring environmental condition, distribution control systems, health care, industrial monitoring and detection of radioactive sources. Not with standing its promising attributes, security in WSN is a big challenge and remains an ongoing research trends. Furthermore the sensor nodes in WSNs are characterized by their resources constraints such as limited power, low bandwidth, short communication range, limited processing, and storage capacity which have made the sensor nodes an easy target. Therefore, in this paper, we present the uses of security aspects of Wireless Sensor Network but we focus on Home Automation, Military Operations, Monitoring Environmental condition like as monitor temperature, pressure, humidity etc.

WSNs are infrastructure-less networks that are why these networks can be easily deployed in any disaster situations like floods, battlefields, etc. They are easy, fast, and cost-effective to deploy for some limited period [3]. Due to the limited energy and open nature of WSNs the energy and security of the network become the major challenge. The network energy can be saved with the help of efficient routing which will enhance the network lifetime. In this paper various routing protocols like LEACH (Low Energy Adaptive Clustering Hierarchy), PEGASIS (Power-Efficient Gathering in Sensor Information Systems), etc. LEACH routing protocols are reviewed that are designed based on clustering architecture where the network is divided into various clusters also known as zones based on their energy.

A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions. A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. Every sensor node is equipped with a transducer, microcomputer, transceiver and power source. The transducer generates electrical signals based on sensed physical effects and phenomena. The microcomputer processes and stores the sensor output. The transceiver receives commands from a central computer and transmits data to that computer. The power for each sensor node is derived from a battery. Currently, WSN (Wireless Sensor Network) is the most standard services employed in commercial and industrial applications, because of its technical development in a processor, communication, and low-power usage of embedded computing devices. The WSN is built with nodes that are used to observe the surroundings like temperature, humidity, pressure, position, vibration, sound etc. These nodes can be used in various real-time applications to perform various tasks like smart detecting, a discovery of neighbor node, data processing and storage, data collection, target tracking, monitor and controlling, synchronization, node localization, and effective routing between the base station and nodes. This paper describes the concept of wireless sensor network.

Wireless Sensor Networks (WSNs) are an emerging technology with a wide range of potential application areas such as monitoring, tracking and controlling.
