Distributed iterative time slot allocation for spectrum sensing information sharing in cognitive radio ad hoc networks

In this paper, distributed iterative time slot allocation algorithms for spectrum sensing information (SSI) sharing in cognitive radio ad hoc networks are proposed. The proposed algorithms are based on a collision detection and acknowledgment scheme, which allows nodes to receive knowledge about collisions with their two-hop neighbors. The nodes use this information to update their operating time slots using a probabilistic approach, i.e., each node maintains a parameter representing the probability of switching the time slot in case of a collision. Both fixed and adaptive probability based schemes are proposed. Simulation results show the rapid convergence and excellent performance of the proposed time slot allocation algorithms.
