| Position-based routing suffers from
inaccurate neighbor positions, especially at low beaconing rates.
In this paper we propose to add dead-reckoning to the forwarder
selection process to predict the positions of neighboring nodes.
We have carried out simulations to investigate the consequences
of this modification and explain the trade-offs. With the
modified algorithm, we achieve a complete packet delivery for
beaconing intervals of as much as 6 seconds for a medium-density
German highway setting. We will show that the dead-reckoning
scheme results in (a) less beacon traffic with equal or better
neighbor position prediction and (b) less overhead induced by
transmit failures when using the same beaconing
frequencies. |
