Anonymous Communication in MANETs Using Pseudonymity in Chain-Based Routing
Abstract
In this paper, we introduce a novel anonymous routing protocol form mobile ad hoc networks (MANETs), named PseudoCAR. In the proposed scheme, a random identifier is assigned as pseudonym to each link of a path during route discovery. Such pseudonyms are fastened privately in intermediate nodes to create a virtual chain between communicating nodes. This mechanism is called Chain-based Routing. Through hiding nodes’ identifiers inside the chain, PseudoCAR realizes sender, receiver, and relationship anonymity in addition to untraceability in the network. In comparison to the similar protocols, the main contributions of PseudoCAR are its simplicity, flexibility and low imposed computational overhead on the network. The operation of the protocol is validated through both analytical results and simulation experiments.
