Wireless sensor networks as gained lots of impact in the real time applications like monitoring, surveillances and tracking. These applications are mainly rely on the collection of critical information where manual information collection is very difficult task. WSNs are more vulnerable to many types of threats, providing security will be very complex due to the resource constraint sensors. This paper is to study and analyze the vulnerabilities and its effect on the performance of sensor networks in cluster based routing protocols.
