Study on Security Protocols in Wireless Sensor Networks

The extremely undefendable to attacks which is being composed of hundreds and thousands of tiny sensory nodes with less energy, memory and power is the existence of wireless sensor network. The area covered by WSN application has raised the level of security to the adoption and consumption of sensor networks without any interrupts throughout the wide area of occurrence. Sensor networks are interacting with very sensitive data and deployed in hostile unattended environments, where the security issues should be concentrated to attain their potential. This paper lights a torch on security of WSN and different attacks in it and mainly focuses on the effect of Denial of Service (DoS) attacks, which is caused by a flood attack where there is a composition of many illegitimate nodes sits inside the network can produce traffic and dampen the security of WSN. On behalf of the security aspects, this paper also has concentrating on the anatomy of security protocols.
