Résumé: Zone Routing Protocol (ZRP) provides a .exible solution for discovering and maintaining routes in the MANET. By adopting the idea of Fisheye State Routing in ZRP, a more e.cient protocol called Fisheye Zone Routing Protocol (FZRP) was proposed in the paper. FZRP provides the advantage of a larger zone with only a little increase of the maintenance overhead. Two levels of routing zone are de.ned in FZRP: the basic zone and the extended zone. Di.erent updating frequencies of changes of link connectivity are associatedwith the basic zone and extended zone. Simulation study has shown that FZRP is more e.cient than ZRP in terms of route .nding cost with only a little increase of the maintenance overhead.
