In our proposed multi-round contention resolution scheme, the splitting contention period leads to an increased effective window size, so the estimation error for the number of contending stations in k-EC is reduced with a relatively small number of idle slots.
One of the contention resolution
strategies applied in core router is the wavelength conversion.
Here, the helper selection phase is further divided into the priority differentiation phase (PDP) and the contention resolution
phase (CRP) of the same priority helpers, which can promptly select the unique optimal helper to improve the cooperation efficiency.
The RTS/CTS based mechanism appears as an enhancement to the basic access mechanism; it reduces contention resolution
overhead in terms of channel waste time due to packet collisions.
