A Review on Secure Multipath Routing Schemes for MANETs

Abstract

Study has substantially investigated routing protocols in ad hoc networks. Most state-of-the-art surveys have concentrated on evaluating and classifying the numerous routing structures suggested for MANET depending on the form of network and the application of the protocol. Security dimensions of routing protocols were not provided adequate consideration and most of MANET's routing protocols were not developed with security specifications in mind. However, protection is a concern, taking into account that ad hoc network applications ought to help essential infrastructures (i.e. defense, healthcare, environmental, etc.). And because these infrastructures are highly reliant on the availability of capital, particular emphasis has been put on supporting a stable, robust, and efficient environment, with one of the added features being multipath routing. The need for protection in fragile ad hoc network implementations has driven researchers from the beginning to develop protected multipath routing protocols or to design security enhancements for established protocols. The present state-of-the-art of secure multipath routing protocols in ad hoc networks is studied in this article.
