Traditional ad-hoc routing protocols typically choose minimum hop
paths for transmissions. In a multi-rate environment, where nodes may elect
between several transmission rates in order to accommodate different channel
conditions, these protocols usually choose paths that contain long range links,
with low effective throughput and low reliability. In this paper, we propose
a mechanism for reactive routing protocols that
leads to the election of high throughput routes while not increasing
significantly the signaling overhead. By allowing a node to have a complete
knowledge of its one-hop neighborhood topology, we are able to increase
significantly the performance of the network through the improvement of the
route election process on multi-rate environments. |
