Abstract(s)
In this paper we present several different approaches
to a routing calculation in an ad-hoc network. By
using different weights for each link, each algorithm generates
a different path, with its own number of hops and maximum
throughput. Tests were performed in our own IEEE 802.11e
simulator and the results allow to conclude that the cross-layer
approach has advantages over the traditional one. In fact, our
proposals delivers up to three times more packets than the
standard one, whilst diminishing the end-to-end delay. Results
show that the proposal which privileges users with a baud rate
near the maximum possible achieves better performance than the
others. A baud rate near the maximum corresponds to links with
the highest signal to interference-plus-noise ratio. The proposed
technique privileges the use of paths with a larger number of
hops, and reduces the packet end-to-end delay.
