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