Trust-Based Energy Efficient Secure Multipath Routing in MANET Using LF-SSO and SH2E

Multipath Routing (MR) technique is much common in Mobile Ad-hoc Networks (MANET) as they overcome single-path routing’s particular limitations. However, by reason of the deficiency of trusted centralized authority and also inadequate resources, attaining energy-effective secure MR is a significant challenge in MANET. Aimed at overcoming these challenges, this work proposes a trust-centred energy-efficient MR scheme for MANET. In this research, primarily, the direct and indirect trust of nodes and paths are examined and centred on these trust values, the secure multipath is selected and also the victim nodes are identified and isolated. Next, the data packets (DPs) are encrypted using the Secret key-centred Hybrid Honey Encryption (SH2E) algorithm to secure the DPs against data transmission (DT) attacks. Next, the Levy Flight centred Shuffled Shepherd Optimization (LF-SSO) Algorithm is applied to discover an optimal path as of the multipath selected. This algorithm improves the network’s lifetime by discovering a path based on path trust, residual node energy, and also the path’s distance. And then, the encrypted DPs are forwarded as of the source node (SN) onto the destination node (DN) over the discovered optimal path, and finally, transmitted to the base station (BS). This work not only considers the energy-efficient secure routing but also considers the route maintenance. The experiential outcomes are given to exhibit the proposed system’s efficacy.
