Inculcating Trust in Hybrid Routing Approach for Securing MANET

Abstract

The rudimentary notion of using MANET is that the exchange of information in between the portable nodes count on the swift arrangement of a momentary network. Also, each node in a MANET can travel spontaneously in any direction and can change its links to the other nodes repeatedly. In hybrid protocols, initially, the routing is established with the help of some proactively prospected routes and later on serves the request with the help of reactive flooding. In MANET, the security and the routing are the two most crucial and challenging aspects that open up a vast area for improvement. Security includes a set of considerations that are adequately funded. Designing a competent routing protocol for wireless ad-hoc network along with the fulfilment of security aspects is a challenging task. MANET demands for a new set of networking strategies to be adopted in order to provide competent and secure overhead free end-to-end communication. In MANET, hybrid routing protocols are considered to be the most effective types of protocols as they take the advantage of both proactive and reactive routing protocols. After performing an intense literature survey, it could be concluded that there is a specific requirement of a protocol hybrid in nature that could include the two most specific factors for MANET (i.e., routing and security). The existing hybrid routing protocols suffers from the problems like optimisation control, images detection, and image quantization. To solve the above-mentioned issues of hybrid routing protocols, various optimization algorithms have been proposed that are natural genetics-inspired. The various techniques that can be used to enhance the security are cryptography, bio-metric, trust-based approach, Hash function algorithm, etc.
