A Survey on Wireless Sensor Networks Security

Wireless Sens or Networks (WSN) is an emerging technology now - a - days and has a wide range of applications such as battlefield surveillance, traffic surveillance, forest fire detection, flood detection etc. But wireless sensor networks are susceptible to a variety of pot ential attacks which obstructs the normal operation of the network. The wireless sensor network nature of communication is unprotected and unsafe because of deployment in hostile environment, limited resources, an automated nature and untrusted broadcast t ransmission media. The most of security techniques are not sufficient in WSN network and security is a vital requirement for network. The intent of this paper is to investigate the security related issues, attacks and Challenges. The introductory sectio n gives brief information on the WSN components and its architecture. Then it deals with some of the major security issues and challenges over wireless sensor networks (WSNs).

The confluence of cheap wireless communication, sensing and computation has produced a new group of smart devices and by using thousands of these kind of devices in self-organizing networks has formed a new technology that is called wireless sensor networks (WSNs). WSNs use sensor nodes that placed in open areas or in public places and with a huge number that creates many problems for the researchers and network designer, for giving an appropriate design for the wireless network. The problems are security, routing of data and processing of large amount of data etc. This paper describes the types of WSNs and the possible solutions for tackling the listed problems and solution of many other problems. This paper will deliver the knowledge about the WSN and types with literature review so that a person can get more knowledge about this emerging field.

A data network is a digital telecommunications network that allows nodes to share resources. Two types of networks are available, wired and wireless networks. Wireless networks become popular because of its wireless setup and its abundant applications in home, business and telecommunications networking. With the invent of sensor which react and notice some type of input from the physical or environmental conditions, such as pressure, temperature, beam, Wireless sensor network developed. The WSN are stretchy, simple to employ and straight forward. They are growing because of low cost and efficient. Wireless Sensor Networks consist of many sensor nodes that are distributed in a field and have physical capabilities to measure or sense things in the real world, do some computations, communicate with each other and deliver result to base station. With the rising expertise, the things on security are also advancing day by day. Though the network completely secured during the time of designing, intruders and attackers always find their way to get inside it and accomplish attacks. This paper presents a noteworthy analysis on the security threats of wireless sensor network. Threats are of two types active and passive attacks. Passive attacks are just listening the communication lines, whereas active attacks are modifying the data in communication lines. Different threats belonging to active and passive threats are studied in detail.

- In this paper, a survey on Wireless Sensor Network (WSN) and their technology, standards, prototype and applications was carried out. A wireless sensor network consists of thousands of inexpensive miniature devices capable of computation, communication and sensing. It provides a bridge between both the real and virtual worlds. Allow the ability to observe the previously non-observable at a fine resolution over large spatio-temporal scales. Have a wide range of potential applications to agriculture, health, transport system, disaster detection, and defence. This paper supports the difficulties of operating such sensor network in the most hostile environments. Although the measurements and analysis demonstrated that control deployment was possible to some extent.

Wireless Sensor Network is an emerging technology that shows great promise for various futuristic applications both for mass public and military. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance future. The inclusion of wireless communication technology also incurs various types of security threats. However, like any other system, security is one of the important issues in any WSN application. The intent of this paper is to investigate the security attacks and mechanism that apply to wireless sensor network. It also discusses Trust Management issue that is important in security.

Wireless Sensor Networks (WSNs) present myriad application opportunities for several applications such as precision agriculture, environmental and habitat monitoring, traffic control, industrial process monitoring and control, home automation and mission-critical surveillance applications such as military surveillance, healthcare (elderly, home monitoring) applications, disaster relief and management, fire detection applications among others. Since WSNs are used in missioncritical tasks, security is an essential requirement. Sensor nodes can easily be compromised by an adversary due to unique constraints inherent in WSNs such as limited sensor node energy, limited computation and communication capabilities and the hostile deployment environments.

Wireless Sensor Network(WSN) is an emerging technology and explored field of researchers worldwide in the past few years, so does the need for effective security mechanisms. The sensing technology combined with processing power and wireless communication makes it lucrative for being exploited in abundance in future. The inclusion of wireless communication technology also incurs various types of security threats due to unattended installation of sensor nodes as sensor networks may interact with sensitive data and /or operate in hostile unattended environments. These security concerns be addressed from the beginning of the system design. The intent of this paper is to investigate the security related issues in wireless sensor networks. In this paper we have explored general security threats in wireless sensor network with extensive study.

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.

With the global use of wireless sensor network technology in different fields and for different purposes such as health care monitoring, earth sensing, air pollution monitoring, military operations monitoring or surveillance system monitoring, a problem arises. Problem that could negatively impact previously started activities and observations if not handled in a right way. Authors of this paper discuss various vulnerabilities and security threads in different applications of WSN in the real world, such as intrusion, node capture attack, black hole attack or selective forwarding attack. Potential countermeasures are proposed formatted as protocols or architectures for secure transfer of data between friendly nodes, compromises on security measures with the goal of achieving secure and reliable connection. This paper could be used as a general representation of WSN security issue with which WSN engineers are faced on a daily basis.
