Abstract

The transport capacity of cognitive radio ad hoc networks is investigated in this paper. Compared with the related works in the literature which mainly give order sense results like scaling laws, we derive an expression of the single-hop transport capacity for the secondary (SR) network under the outage constraint of the primary (PR) network. The Aloha medium access control (MAC) protocol and the nearest neighbor routing protocol are considered. Through stochastic geometric analysis, it is shown that the outage probability of the PR network and the transport capacity of the SR network are mainly dominated by the node density of the SR network and the medium access probability p of the MAC protocol. Besides, the value p is optimized to maximize the transport capacity of the SR network.
