Review of security enhancement techniques for Wireless Sensor Network

摘要

Wireless communication technologies are experiencing rapid advancement because of its high quality and high speed of information transmission from one place to another. With this advancement, it is important to ensure the security of Wireless Sensor Networks. One of the major security issues in WSNs is eavesdropping which is an attack that captures information transmitted over a network by other devices. Eavesdropping attacks are insidious, and it is difficult to know they are occurring. Once you connected to a network, users may unwittingly feed sensitive information like passwords, account numbers, surfing, the content of email messages, etc. Therefore, security enhancement in communication in wireless networks is in demand. This paper will focus on the Wireless sensor networks, its applications, and limitations. Secondly, the paper will introduce the concept of Eavesdropping issue in WSNs. This research will explore the existing techniques used to detect the network vulnerable to eavesdropping attack. Also, the paper will review the various routing protocols and algorithms used by different researchers for security enhancement and protecting wireless networks from attacks or security issues.
