摘要：MANETs are infrastructure free network, hence are mostly vulnerable to attacks and maintaining the anonymity of the nodes is also becoming a major concern. Most of the existing geographical routing methodology in Mobile Ad Hoc Networks (MANET) does not include any position update mechanism for anonymous mobile nodes. In this paper, we propose a secure geographical routing which uses an adaptive position update technique for MANET. When source wants to transmit the data to destination, it establishes a secured geographical route using group signature. Then a position update technique is used to dynamically adjust the position of nodes based on mobility and network forwarding patterns. The malicious node detection technique is used to detect the malicious node. By simulation results, we show that the proposed technique reduces packet dropping and enhances the packet delivery ratio.
