Self-organized forensic support in MANETs

Abstract

A distributed hash table (DHT) based approach for supporting forensic capability in mobile ad hoc networks (MANETs) is presented. The DHT-based approach has been modified to inhibit recursive increase in bandwidth consumption due to forensic activity - the process of logging is associated with that of packet delivery via customizable decreasing functions. Simulation has revealed that this approach limits the bandwidth requirement for forensic activities, although it requires a trade-off between bandwidth consumption and effective logging. The focus is to design a self-organized logging system over networks with dynamic topology.
