Abstract

Key distribution and security are the essential requirement in MANETs. In our paper we are using intrusion detection nodes to monitor and detect the malicious activities as well as finding the best node to select as PKGs based on security and energy constrains. Instead of selecting a single node as PKG, selecting t nodes using intrusion detection systems and the PKG task is distributed among these nodes using DPKG protocol. We are using intrusion detection nodes as a filter for enhance the security, increase network lifetime, preventing the self organization nature.
