Abstract
This work introduces the concept of link-state tracking
and its application to routing in a Mobile Ad hoc Network (MANET). Literature
abounds in routing protocols for ad hoc networks. However, routing protocols
based on stability of links are rather limited, and none of them investigate
the link-stability prediction based approach that we propose. We use the
link-stability information to predict route stability. Using extensive
and realistic simulations, we show that routing based on route stability is a
powerful idea since the main problem in a MANET is the
high frequency of route breakage. We designed and implemented a new routing
protocol in ns-2, incorporating this idea
and several other optimizations, and compared its performance with that of an existing
popular MANET protocol (Dynamic Source Routing). Results indicate that our
scheme outperforms the traditional approaches to routing. The link-stability
prediction algorithm used is based on a Kalman Filter
and was developed as part of our earlier work.
