This paper presents TIGHT, a geographic routing protocol for cognitive radio mobile ad hoc networks. TIGHT offers three routing modes and allows secondary users to fully explore the transmission opportunities over a primary channel without affecting primary users (PUs). The greedy mode routes a packet via greedy geographic forwarding until a PU region is encountered and then further routes the packet...
Because of the instability of link quality, traditional network routing protocols, which are mainly based on the condition of "Best Path", can not work very well over wireless mesh networks. Forwarding packets along the "Best Path" may also induce load imbalance among nodes. This paper presents a novel routing protocol named HPRP (Hierarchical Probabilistic Routing Protocol) for...
