Multipath routing protocols for mobile ad hoc networks: Security issues and performance evaluation

Abstract

The evolution of wireless network technologies and mobile computing hardware made possible the introduction of various applications in mobile ad hoc networks. These applications have increased requirements regarding security and the acceptable delays in order to provide high quality services. Multipath routing protocols were designed to address these challenges. With the use of multiple paths for the communication between a source and a destination, the autonomic user becomes almost unaware of a possible network failure, due to security attacks or link collapses. Several secure multipath routing protocols have been proposed but little performance information and extensive comparisons are available. In this paper, we briefly describe some security issues that multipath routing protocols face and we evaluate the performance of three existing secure routing protocols under different traffic conditions and mobility patterns. © IFIP International Federation for Information Processing 2006.
