A Ubiquitous Solution for Mitigation of Black Hole Attack in Cognitive Radio

Abstract

In the current scenario Cognitive Radio (CR) has become one of the best available solution for spectrum shortage problem. Moreover, for secure data transmission over these networks it is mandatory to make these networks robust and less vulnerable against the various types of attacks. Through this paper we have presented a ubiquitous solution for one of the attack viz. black hole attack. Its implementation and simulation in detail with PDR and Throughput. The paper deals with different type of attacks and protocols explained well here. Further there is implemention of algorithm on different parameters to achieve the improved rates than earlier solutions. The paper also deals with question of selecting AODV as it protocol used in simulation. Many aspects of attacks, secure network environment are explained here in this paper. Finally in simulation we got improved results for the parameters taken with some modification in AODV protocol.
