Wireless Sensor Network Security: A Survey

Abstract

As wireless sensor networks continue to grow, so does the need for effective security mechanisms. A wireless Sensor network consists of hundreds or thousands of low cost, low power and self-organizing nodes which are highly distributed. Due to the reason that the sensor nodes are highly distributed, there is a need of security in the network. Due to inherent resource and computing constraints, security in sensor networks poses different challenges than traditional net-work/computer security. There is currently enormous research potential in the field of wireless sensor network security. We survey the major issues in wireless sensor network security, and present the constraint and the requirements in the sensor security. This paper focuses on the various current attacks on wireless sensor network, and finally prevention from attacks.
Keywords: Introduction, Constraint to security, Attacks, Prevention from Attacks.
