Analysis of Inconsistent Routing Components in Reactive Routing Protocols

Abstract

In reactive routing protocols, additional routing information is often collected
to reduce the response time and the overhead of the future routing demands.
However, these protocols do not have any mechanism to refresh this routing information
and soon it become obsolete. Therefore, routing components based on this
prior-to-demand collected information are not consistent with the reactive nature
of the protocol. In this work, we have identified such inconsistent components in
AODV routing protocol and have analyzed their effect. Our simulation based analysis
has revealed that the presence and use of stale routing information degrades the
protocol performance. However, if the dependency of protocol operations on this
obsolete information is reduced, the protocol performs better in terms of overhead
and packet delivery ratio.
