This work analyses the performance of a Dynamic Spectrum Access (DSA) network with secondary nodes to provide Internet services, and studies the impact of malicious nodes and cooperative secondary nodes on the performance of the network and spectrum utilization. The work mathematically models the throughput, latency, and spectrum utilization with varying numbers of malicious nodes, secondary nodes, miss probabilities, and false alarm probabilities, and studies their effect on the performance of the network. The results point to rapid spectrum starvation as the number of malicious nodes increase, as well as the negative impact of too many secondary nodes crowding out available spectrum with resultant degradation of throughput and latency
