Mobile Ad-hoc Network (MANET) is a cluster of wireless mobile hosts with changing topological structures. MANET requires a routing protocol based on the dynamic path and the lack of a core administration and coordination that threads too many vulnerable attacks such as wormhole attach, false data injection, and so on. The radically used proactive protocols such as AODV, DSR, and TORA are not designed to challenge the malicious attacks. In line with this security issue in the MANET, a novel Dynamic Source Routing (DSR) based proactive protocol is designed with enhanced security framework. The proposed protocol is the Dynamic Source Secure Routing (DSSR) protocol with Digital Signature, and Dydog Mechanism integrated with Twofish algorithm which is designed to overcome the wormhole, session attack, and false-data injection. The cryptographic algorithm is adopted to ensure authentication, non-repudiation, and integrity of MANETs. The performance metrics of DSSR such as throughput, end-to-end delay, and energy spent, Packet Delivery Ratios (PDRs), and routing overheads is related with the traditional DSR protocol using the NS-2 simulator. Also, data packets prone to session attacks, false data detection attacks and wormhole attacks are detected.
