Fisheye zone routing protocol: A multi-level zone routing protocol for mobile ad hoc networks

[[abstract]]Zone Routing Protocol (ZRP) provides a flexible solution for discovering and maintaining routes in the MANET. By adopting the idea of Fisheye State Routing in ZRP, a more efficient 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 defined in FZRP: the basic zone and the extended zone. Different updating frequencies of changes of link connectivity are associated with the basic zone and extended zone. Simulation study has shown that FZRP is more efficient than ZRP in terms of route finding cost with only a little increase of the maintenance overhead. (c) 2006 Elsevier B.V.
