Routing is an important issue in cognitive radio ad hoc networks (CRAHNs) owing to the stochastic activity of primary users (PUs). In particular, route stability remains an important issue in the CRAHN protocols. In this paper, the authors propose a stability-weighted cumulative expected transmission time (SWCETT) routing protocol. The SWCETT routing protocol aims towards providing the most optimal route based on both quality of service (QoS) metrics, such as delay and throughput, and stability of the route in the CRAHN. The performance of the SWCETT routing protocol is determined through simulations and compared with other routing protocols. The proposed routing protocol is capable of providing better delay and throughput than other routing protocols. The results prove the importance of the route stability metric in raising the performance of CRAHNs.

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 reflect 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 heterogeneous 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.
