Inter-piconet communications in Cognitive Personal Area Networks with prioritized exchange of synchronization information

This paper presents inter-piconet communications in the scenario where a shared bridge node connects two Cognitive Personal Area Networks (CPANs). The bridge carries both inter-CPAN traffic and synchronization information. The bridge exchanges synchronization information in a prioritized manner, which ensures that the two CPANs can coexist without operating on the same channel at the same time. We validate the network performance by analyzing the frequency of synchronization information exchanges. The simulation results also provide insight into the impact of various traffic. The results indicate that the proposed method is effective and efficient when the traffic load and the frequency of synchronization information exchanges are low to moderate.
