For decades, simulations have been the means to study the behavior and analyze the performance of engineering, computer science, and military applications. In the sequential discrete-event driven simulations, the events are executed sequentially in an increasing order of their timestamp. Simulation of large complex applications using sequential simulators often turns out to be infeasible due to computer...
Cognitive radios (CR) have the ability to dynamically adapt to local spectrum availability. In a multi-hop wireless network comprised of CR-enabled devices, medium access control (MAC) layer scheduling for data communication involves assignment of timeslots and channels to either links or nodes in the network. The number of channels available and the channel identities vary from one node to another...
In a cognitive radio (CR) network, MAC-layer configuration involves determining a common set of channels to facilitate communication among participating nodes. Further, the availability of multiple channels and frequent channel switches add to the complexity of route selection. Knowledge of the global network topology can be used to solve the above-described problems. In this paper, we propose a distributed...
