Throughput performance of route selection schemes in cognitive ad hoc networks
Peng Hu, Mohamed A. Ibnkahla · 2013
As an important topic in cognitive radio ad hoc networks (CRAHNs) driven by local observation and control, throughput performance is closely related to the underlay/overlay spectrum sharing, medium access probability and route selection schemes. This paper discusses the theoretical throughput performance of a CRAHN based on local control and observation. We analyze the scaling law of throughput for CRAHNs using two route selection schemes in multi-hop transmission scenarios. Our work extends the current throughput analysis in single-hop cognitive radio networks to CRAHNs. We show the theoretical results based on the theory of stochastic geometry in the network level.
