An analysis of ASMA trust evolution in a dense subway environment

Security in Mobile Ad hoc NETworks (MANETs) is a very prolific research topic. Many solutions have already been proposed to solve important security flaws regarding routing protocols conceived for these emerging networks. However most of them just focus on a small part of the security problems and only few frameworks have been proposed yet. In this paper we present an analysis study of a new framework named Adaptive Secured Multipath for Ad hoc networks (ASMA) that may be used to combine different security mechanisms and provide a global security solution. To improve the security of the framework, a new structure, named MacroGraph, is defined applying multipath routing and trust management. To analyze our solution, we focus on a realistic environment representing a subway and study the trust evolution of ASMA under different attack configurations.
