MANET is an autonomous network of nodes with capability of movement and without any necessity of infrastructure for connectivity. Due to mobility of nodes, network topology changes continuously characterized by network partitioning and routing disruptions. Dragon fly topology is used to improve the network throughput and reduce latency in internet. The hierarchical nature of Dragon fly reduces the network diameter, cost and latency. This work proposes Dragon fly clustered energy efficient ant colony based AODV DC-EEAAODV protocol extending the concepts of Dragon fly topology to MANET and ant colony based route selection with goal to improve network QOS and life time of the network. Due to hierarchical nature, the impact of attacks like gray, black hole on network is high and this work proposes efficient routing resilient against gray and black hole attacks for Dragon fly based MANET. The simulation of the proposed DC-EEAAODV is done in NS2 environment and performance of the proposed protocol is compared against AOMDV and Dragon fly based FFAOMDV to prove the efficiency of the proposed DC-EEAAODV protocol.
