BRD: Bilateral route discovery in mobile ad hoc networks

Abstract

Traditionally, route discovery in MANETs operates in unilateral (source-initiated) manner. We propose a new scheme called bilateral route discovery (BRD), where both source and destination actively participate in a route discovery process. BRD has the potential to reduce the control overhead by one half. As an underlying protocol for BRD, we propose gratuitous route error reporting (GRER) to notify the destination of a broken route. The destination can thus play an active role in the upcoming route re-discovery. © IFIP International Federation for Information Processing 2007.
