A Mobile Adhoc Network (MANET) includes a set of independent mobile nodes which communicates with each other by means of radio waves.The construction of nodes depends on the network actions and hence MANTE has a dynamic shape and a limited bandwidth with complete wireless connectivity.As MANETs are dynamic, the network topology would change often.Hence, it is important to frequently update the network information at each and every node for achieving an efficient data routing.The design of routing protocol with energy efficiency and security is a demanding task.To overcome this task, the previous system designed an energy-efficient secured routing protocol called as Secure Optimized Link State Routing (SOLSR) protocol.However it does not efficiently select the Multipoint Relays (MPRs) to forward control messages.In order to solve this problem the proposed system designs an efficient Secure Optimized Link State Routing (SOLSR) Protocol with Firefly Algorithm (FA) for secure packet transmission.In this protocol, the FA is used to optimally select the MPRs with the help of packet delay and Packet Delivery Ratio (PDR) of the node.After choosing the link, the power statuses of the nodes are checked and routes are established.Finally compute group key distribution using the generated keys.In order to avoid non authorised nodes and use of the same group key in more than some amount of data, the group key is changed regularly.Finally the secure Source Anonymous Message Authentication Scheme (SAMA) is utilized to provide the communication privacy.The experimental results show that the proposed system achieves better performance compared with the existing system in terms of PDR, energy consumption and end to end delay.
