Abstract: Recent advancements in MEMS technologies and development in the area of low power microcontrollers have resulted as implementation of wireless sensor networks in real life problem solving in areas like traffic monitoring, patient monitoring , battlefield surveillance. These wireless sensors are very small in size and are operated at low power for low data rate applications. WSN nodes include features like scalability, self-organizing, self-healing. WSN nodes face many challenges starting from deployment till their life span which is dependent on very low battery strength. Since these nodes are operated in unattended environments, many security threats are for them to survive. These nodes face variety of attacks at different layers of their architecture, ranging from physical stealing, tempering to reprogramming. Applying any traditional security mechanism over wireless sensor nodes is also not possible as those traditional algorithms or protocols consume very much processing and power due to their complexity. In this paper, we have mentioned. This paper aims at reporting an initial introduction of WSN, WSN architecture, challenges and security threats subsequently.
