Dynamic resource allocation for military communications satellites with cognitive users

This paper presents a Dynamic Resource Allocation (DRA) algorithm for military satellite communication networks based upon a PI controller. The DRA is designed in such a way as to allow cognitive users to proactively fill unused resources or bandwidth without a large negative impact on the primary users. Simulations were conducted to find the good choices for PI gains as well as to identify the cognitive user's impact on the primary users. The simulations show that a cognitive user is able to use the network with little impact on the primary users. Also, via simulations, the DRA algorithm was shown to perform relatively well in the presence of selfish users and correlated traffic. Finally, a preliminary formal analysis of the DBA algorithm's performance was undertaken.
