Abstract

Mobility of nodes and dynamic changing topology creates security issues in MANETs making it vulnerable to some prominent attacks. Black and gray hole attacks drop the data packets in AODV. In this paper we propose a technique to detect and isolate malicious nodes. A cost effective Hash function to compute Message Digest (MD) is used for secure data transmission and data integrity in AODV. Malicious node is detected with the identification number or hop count. The security analysis of the existing ADOV and modified AODV is discussed. On the basis of analysis, we conclude that the proposed AODV is more secure as it provides cost effective secure mechanism for data transmission.
