摘要：Over the past decade, there has been a lot of research in the area of Mobile Ad-hoc NETwork(MANET). MANETs are autonomous, self-organized, infrastructure-less and decentralized wireless systems in which mobile nodes behave as a router as well as host. MANETs are mainly useful in military and other tactical applications such as emergency rescues. Security is the main challenge in these networks due to its nature as mobile and open media. There are various attacks among them blackhole and grayhole are most affecting the network working by dropping packets. In this paper the performance of MANET routing protocols, AODV and DSR, with blackhole and grayhole attack have been analysed under different scenarios using CBR traffic using NS2 taking various parameters such packet delivery ratio, average end to end delay and average throughput to compare and evaluate their performance.
