Abstract :
We formulate fragmentation ratio to quantify bandwidth fragmentation, and propose two fragmentation-aware RSA algorithms to alleviating it in both static planning and dynamic provisioning of O-OFDM networks. Simulation results indicate that the proposed RSA algorithms outperform two existing ones.
