Description
Summary:As the range of coverage for radio cells is gradually becoming smaller, the procedures for mobile terminal call setup and control become more 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 study of WDM-based PCN Architecture, a channel allocation algorithm is used to keep the offset conflict probability as low as possible. imulation results show that the wavelength-offset assignment scheme performs better than the other schemes in offset conflict probability (OCP) under moderate roaming rates.
