A Multiple-frequency Transmission Scheduling Scheme for Mesh Networks that Employ Spectrum Sharing
Abstract
The reallocation of underutilized spectrum becomes increasingly important as available frequency bands continue to diminish. The Citizens Broadband Radio Service (CBRS) presents spectrum-sharing opportunities, but the interference protection it requires for legacy users can create network performance issues for newer users that look to share the spectrum. To combat these issues, we introduce bridge nodes into the network - dedicated traffic-forwarding nodes that help ease the connectivity issues and bottlenecking caused by legacy node protection protocols. In this thesis, we present the augmented connected dominating set (ACDS) algorithm for selecting bridge nodes from a list of bridge node candidates within a network. Simulation results display the effectiveness of this selection scheme in terms of end-to-end success rate, end-to-end throughput, and end-to-end delay in a variety of network topology scenarios. We show the effectiveness of our algorithm by comparing it to simpler bridge node selection schemes.
