Routing in HF ad-hoc WANs

High frequency (HF) radio is commonly used to extend wireless communications beyond the line-of-sight range that limits the higher frequency bands. Despite such long-range coverage, however, indirect routing is sometimes required even in HF networks. In addition, HF radio and other wireless technologies are emerging as a means to interconnect wired subnetworks in various mobile and contingency applications. In this paper, we introduce WARRP, a wireless address resolution and routing protocol that is specifically designed to integrate single-relay route discovery with address resolution in such ad-hoc WAN.
