Secure Mechanism For Wireless Sensor Networks - A Review

Abstract

Wireless Sensor Network (WSN) is an emerging technology that is very usefu l for various futuristic applications both for public and military. As the use of wireless sensor networks continue to grow, so it should require effective security mechanisms. So to ensure the security of communication and data access control in WSN is paramount importance. Because sensor networks may interact with sensitive data and operate in hostile unattended environments, it is important that these security concerns should be addressed from the beginning of the system design. However because of inh erent resource and computing constraints, security in sensor networks poses different challenges than traditional network security. There is currently enormous research is present in the field of wireless sensor network security. Thus, familiarity with t he wireless sensor network,attack on WSN and security systems design for WSN will benefit researchers greatly. With this in mind , I survey the major topics in wireless sensor network security, and presentmany of the current attacks, and finally list their corresponding defensive measures
