Velez, “Seeking for an Optimal Route in IEEE 802.11e Ad-Hoc Networks,” in Proc. of IEEE VTC2009-Fall - IEEE Semi Annual Vehicular Technology Conference, Anchorage, Alaska, USA, Sep. 2009.http://hdl.handle.net/10400.6/15033In 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.engRoutingIEEE 802.11eAd-hoc networksconference object10.1109/VETECF.2009.5378970
