Multi-hop routing protocol in cognitive radio mobile ad hoc networks
(CRMANETs) is a critical issue. Furthermore, the routing metric used in
multi-hop CRMANETs should re- flect the bands availability, the links
quality, the PU activities and quality of service (QoS) requirements of SUs.
For the best of our knowledge, many of researchers investigated the
performance of the different routing protocols in a homogeneous
environment only. In this paper, we propose a heterogeneous cognitive radio
routing protocol (HCR) operates in het- erogeneous environment (i.e. the
route from source to destination utilize the licensed and unlicensed spectrum
bands). The proposed routing protocol is carefully developed to make a
tradeoff between the channel diversity of the routing path along with the
CRMANETs throughput. Using simulations, we discuss the performance of
the proposed HCR routing protocol and compare it with the AODV routing
protocol using a discrete-event simulation which we developed using
JAVA platform.
