Link Scheduling Scheme for Multi-Hop Cognitive Radio Ad Hoc Networks

In this paper, we propose to apply a centre scheduling algorithm in the CRAHNs with a cluster. In this network, the cluster head assigns time slots to each node so that every node can be fair to transfer data. The scheme schedules the links to the same destination node first, which has the largest topology structure, then another destination node whose topology structure is larger than the rest. The algorithm presented in this paper considers both the fairness and the spatial reuse, and the simulation results show that this algorithm still has a good performance when the topology is so large.
