Abstract: Based on the researching of disturbing on radio, hidden and exposed terminal problem, a bandwidth
guaranteed routing protocol in ad hoc networks was proposed to find a bandwidth guaranteed routing path on demand and
reserve enough bandwidth resources to support communication. Theoretic analysis showed that routing path found by
BGRP could guaranteed in bandwidth and reserve bandwidth was exact. Simulation result shows that, in terms of
available bandwidth, BGRP outperforms INSIGNIA and BGSR algorithm. Furthermore, BGRP can scale well in large
networks for low message overhead.
Key words: ad hoc; bandwidth; routing protocol; resource reserve
