AODVH: Ad hoc On-demand Distance Vector Routing for Hybrid Nodes
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 challenging for transmitting video and running high bandwidth applications 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. The 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.
