RBR: Refinement-based route maintenance protocol in wireless ad hoc networks

Abstract

In this paper, we propose a so-called refinement-based routing protocol that uses dynamic route redirection to provide proactive route selection and maintenance to on-demand routing algorithms so that the benefits of both types of routing algorithms can be combined and their drawbacks minimized. Experimental results demonstrate that adding the refinement-based routing protocol to AODV significantly reduces the number of broken paths and the end-to-end packet latency when compared with the pure on-demand routing protocol, AODV. © 2005 by International Federation for Information Processing.
