MACO-DHKE Based Secure Data Transmission in MANETs

Abstract

Mobile ad hoc networks (MANETs) are the self-sufficient nodes with their unique characteristics, such as open wireless mediums and self-motivated topology, which suffers from security weaknesses. Due to the complexity of the MANET security architecture, it is difficult to detect and prevent security issues in the wired networks. Hence, this paper proposes a secure and QoS-aware data transmission in the MANET that improves the efficiency of the transmission. The optimal route, which is the shortest possible path, is chosen using the modified ant colony optimization algorithm (MACO algorithm) and the secure transmission in MANET is ensured using the Diffie-Hellman key-exchange algorithm (DHKE strategy). The key exchange method is used to improve the security of the transmission of the MANET. This paper shows a high transmission rate on a secure path with a higher PDR and throughput.
