GAMANET: A ganatic algorithm approach for hierarchical group key management in mobile adhoc network

Mobile adhoc network (MANET) is a seamless integration of nodes that can be sender, recipient or relay and may unaware until they come in contact with each other in a decentralized network. Communication should takes place in a secure manner even with the changes on topology, bandwidth, network size, resources etc. The core aspect of establishing trust among the mobile nodes can do with the help of authentication check by exchanging keys. In this paper, we propose a genetic algorithm approach for hierarchical group key management scheme by simple rekeying technique on frequent scalable and high mobility nodes. The rekeying approach (in our scheme) distributes key with decentralize authority require single round and achieves consumption of energy during exchanging of rekeying messages with simplified number of bits. Few approaches such as OFT, CRTDH, GDH, and BH uses 3 rounds and DLKH, DOWF uses based on number of members in the network. The proposed approach (On our method) reduces energy consumption, computation, and communication compare to the existing scheme.
