Abstract:
Two-stage access network structure is widely used
in fixed and mobile access networks such as HFC
(Hybrid Fibre/Coaxial) and BSS (Base Station System).
In this paper, we introduce a new two-stage access
scheme that employs random access and centralized
polling methods corresponding to the two stages
respectively. The new scheme’s MAC (Medium Access
Control) protocol procedure is presented based on
DOCSIS standard. The performance of the mechanism
in terms of access delay and throughput is evaluated
and analyzed using computer simulating experiments.
The results show the new access mechanism is
efficient.
