Wireless sensor networks are application based special networks consists of tiny sensor nodes deployed in a specific area. They are prone to adversaries due to distributed behavior and deployment in distant areas. Blackhole attack is a type of denial of service attack in which attacker attracts all the packets from nodes and swallows the packets i.e. the packets are not forwarded to the sink. The paper deals clustering based sensor networks with two cluster heads in each cluster that are being used for blackhole detection and prevention.
