Abstract :
As the range of radio cells is gradually getting smaller, the procedures for mobile terminal call setup and control become complicated due to the high handoff frequency. The broadcast nature of WDM star couplers makes the handoff scheme easier, and reduces the number of continuous reconnections. In this paper, based on the WDM-based PCN architecture, a channel allocation algorithm is used to keep the offset conflict probability as low as possible. Simulation results show that the wavelength-offset assignment scheme performs better than the other schemes in offset conflict probability under moderate roaming rate
