Security of wireless network is a highly stimulating issue of today’s life. The validation of all route messages is very problematic one due to the mobility and frequently modifying topology of the MANET. So in this paper, a DCR-based hybrid Black-hole/Gray-hole attack detection (HDCR) is proposed. In this approach, the malicious node attacks are identified by the Data to Control Packet Ratio value to avoid false detection. Data-to-Control Packet Ratio (DCR) is the ratio of number of data packet send by the node to number of control packet sent by the node. Each node will calculate the DCR value of its neighbour nodes in its own routing table. The maximum number of RREQ sent by any node is proportional to the DCR value of the node maintained by its neighbours. The experimental results compared the proposed HDCR detection with Hybrid detection method.
