Abstract:
A Mobile Ad Hoc Network (MANET) is a set of wireless nodes which co-operatively for man infra structure less network. MANETs are intended to play a vital role in several group based applications. Ensuring secure communication is a major research a venue in MANETs because of the dynamic topology and energy constraint. To achieve this ID–based key management was introduced. Most of the existing systems have provided various key management schemes like ID–based multiple secret key with threshold cryptography, Hierarchical Identity Based Key management, etc. Though these schemes are considered to be efficient the energy consumption is high. This leads to the need of an energy efficient key management scheme. Our proposed scheme EEIM-Energy Efficient Identity Management scheme focuses on: 1)Topological Structure and 2)GroupKeyManagement. The individual node properties are being verified and the nodes are being organized into clusters based on their transmission range. An optimized method is being implemented for the formation of cluster and election of cluster head. The proposed scheme saves time and energy for frequent cluster updations and key updations. To prevent then on-group members from reading data, the complex key called Group Key is being generated. The forward and backward secrecy of the group key is being maintained. Group key avoids the issue of certificates and third party involvement. Thus in our proposed scheme, we Reduce the amount of energy consumed for cluster formation and CHelection. Frequent updations, the possibility of key hacking and exchanging certificates are being reduced. The results show that the throughput, life time of the nodes, link stability is increased with minimum consumption of energy. Our proposed scheme also reduces overhead, end to end delay, packetloss and jitter.
