The growth in wireless devices and multimedia applications has led to increase in spectrum usage in recent past. One of the credible solutions to overcome this shortcoming is by the usage of Cognitive Radios (CR). The Cognitive Radio has spectrum sensing capabilities and thus can improve spectrum usage. The ad hoc network employing CR are termed as Cognitive Radio Ad Hoc Networks (CRAHN). To establish...

In ad hoc networks, each node acts as a router to support multiple hops to overcome limited range of packet radios. While a variety of routing protocols have been developed recently, a class of routing schemes called on-demand protocols have attracted a lot of attentions due to their low...
