An ad-hoc network is referred as wireless network in which the nodes in the network are independent of each other and free to move. Since nodes are independent, there is a great extent of loss of packet data while transferring the packet from source to destination. There is a chance of some nodes to be misbehaved. This unsecured ad-hoc network environment is caused due to the dynamic nature of networks and node mobility. Key management is also difficult in ad-hoc network. Several researches have proposed techniques using clusters for an efficient communication from one network to other network. The previous work presented a fully-distributed ID-based Multiple secrets Key Management scheme (IMKM) for a secure communication.
