Bosupally Nanda Kumar, K. Jaya Sankar . Spectrum Sensing based Trust Aware Routing for Cognitive Radio Ad hoc Networks (CRAHNs). International Journal of Computer Applications. 185, 43 ( Nov 2023), 36-42. DOI=10.5120/ijca2023923242
Routing in Cognitive Radio Ad hoc Networks (CRAHNs) is a regarded as a challenging task due to the dynamic nature of frequency bands in Cognitive Radio technology. Due to varying frequency bands, the traditional networking routing protocols cannot be applied over CRAHNs. Further, the unavailability of channel information also impacts the network performance. Along with these issues, the presence of adversary nodes and their malicious actions deteriorates the network performance drastically. Hence, this paper introduces a new routing mechanism called as Spectrum Sensing based Trust Aware Routing (SSTAR) for CRAHNs. According to SSTAR, each node subjects to the computation of a trust value, cost associated with channel linked and the probability of the presence of Primary users. SSTAR forms a composite metric is formulated and establishes a secure path for source and destination node pair in the network. Simulation experiments on the proposed SSTAR prove the efficiency in terms of packet delivery ratio, delay and malicious detection rate.
