Abstract--Ad hoc networks are characterized by nodes which
are usually connected by low data rate Radio Frequency (RF)
links when compared to optical links. RF links make it challeng-
ing for transmitting video and running high bandwidth appli-
cations over ad hoc networks. The objective of this paper is to
develop a novel routing protocol for Ad hoc networks consisting
of hybrid nodes using high bandwidth Free Space Optical (FSO)
and RF links, with FSO being the primary link and RF as backup
in case of FSO link failures. Our protocol, called Ad hoc On-
demand Distance Vector hybrid (AODVH), computes multiple
"FSO only" paths to ensure high data rate communication, and
uses "hybrid paths" consisting of FSO and RF links as backups.
