The Security Requirements And Challenges Of Wsns

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

In Extensible Authentication Protocol, a random set of authentication mechanism is used such as using smart cards or certificates or using user’s credentials. Primarily the WLAN uses EAP for the purpose of passing messages during the authentication process.

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

More specifically, a sensor is "a device that responds to phenomena, such as light, pressure, or heat, and generates a signal that can be measured or interpreted" [16]. The sensor network community often defines a sensor node as a wireless device which is small, capable of responding to one or several stimuli, processing the data and transmitting the information over a short distance using a radio link. Sensor nodes contain electronic circuits for minimizing power consumption [17]. Sensors are for measuring sound, light and temperature that is typically thought. However, sensors can measure other variables, such as vibrations or electromagnetic fields [18]. Sensor transmits values wirelessly to one or several BSs

Non repudiation: It ensures that nodes in the MANETs should not deny their responsibility of actions while sending and receiving the data packets. With the help of

Within this article, the authors states that in order to provide a safe and secure wireless network, they outlined the counter attacks and measures for the security of wireless networks. Some of the counter attacks that the authors have listed includes, system security - which breakdowns to administrative level security, physical level security, and technical level security, and information security (Ameen et al, 2012). For the purpose of answering the previous question, the main counter attack that would best defend against the problems would be system security - particularly the administrative level security. At this level of security, administrative control over the system by establishing a well defined user hierarchy plus a strong authentication measures, can prevent security breaches of WLANs from

Wireless networks are considered vulnerable when an incident occurs that exploits the capability to perform the desired requirement of maintaining performance and concealment of data. Most vulnerabilities happen because of the science behind a wireless network, the fact that it uses air as a medium makes it harder to protects because the environment of air is not stable and when it comes to delivering sacred information you must be on

Wireless devices, like all technologies that provide external access to corporate networks, present security challenges. With wireless standards and practices still rapidly evolving, it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and wireless networks.

UDP uses a simple transmission model without implicit hand-shaking dialogues for providing reliability, ordering, or data integrity. Thus, UDP provides an unreliable service and datagrams may arrive out of order, appear duplicated, or go missing without notice. UDP

Wireless computer networks have become very common in the past several years. The convenience with which computer users can utilize internet connections, without having a network cable attached to their computers, makes wireless networks extraordinarily popular in today’s on-the-go society. Homes, offices, and public businesses (e.g., hotels, coffee shops, restaurants, etc.) all frequently have active wireless computer networks. As is the case with hard-wired computer networks, security is very important in wireless networking environments, even more so because one is not physically connected to the network. This paper will examine many of the security issues revolving around wireless networks, as well as ways to protect such networks from vulnerabilities and attacks.

A wireless protocol that is intended to deliver the privacy comparable to that of a wired network.

WAP does not offer end– to– end security. WAP contraptions talk with web servers through a widely appealing WAP entrance. WTLS is quite recently used between the device and the section, while SSL/TLS can be used between the gateway and the web server on the Internet. This infers the WAP gateway contains, at scarcest for some time span, un mixed data. The entryway dealers need to figure out how to ensure that the unscrambling and re– encryption occurs in memory, that keys and decoded data are never saved to plate, and that all memory used as a noteworthy part of the encryption and disentangling process is cleared before offered back to the working structure. The WAP configuration irrefutably acknowledge that the customer of the

Routing in WSNs is very challenging due to the inherent characteristics that distinguish these networks from other wireless networks like mobile ad hoc networks or cellular networks. Due to the relatively large number of sensor nodes, it is not possible to build a global addressing scheme for the deployment of a large number of sensor nodes as the overhead of ID maintenance is high. Thus they require careful resource management. This paper describes various routing protocols and their comparison and working of LEACH protocol and enhanced LEACH protocol.

With proceed in technology,these sensor networks collected of little and price efficient sense devices set among wireless broadcasting transceiver for atmosphere monitor have turn into reasonable. The key benefit of using these little devices to examine the surroundings is that it does not require communications such as electric
