SECURITY ISSUES, ATTACKS AND CHALLENGES IN WIRELESS SENSOR NETWORK

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)
