Abstract: Black hole attack which is a kind of Denial of Service (DOS) attack is one of the major problems in ad hoc network security. In this paper we propose a solution called Enhanced Dynamic Source Routing (EDSR) Protocol to detect black hole attack. Our technique is an ACK-based detection technique which is capable of finding whether data packets are reaching the destination or not, thus detecting black hole attacks. The experiment results show that our protocol is able to achieve routing security with 16% increase in packet delivery ratio and 31% reduction in packet loss rate when compared to standard DSR under black hole attack. Our technique is light weight because it does not involve high computational complexity and also scalable because it achieves better packet delivery ratio than standard DSR in a network size of 200 nodes.
Keywords: black hole attacks; DOS attacks; denial of service; DSR routing protocol; wireless ad hoc networks; wireless networks; enhanced dynamic source routing; network security; routing security; packet delivery ratio; packet loss rate.
