A comparison based on simulation study has been made by using OWns (Optical WDM network simulator) to investigate effects on three network performance parameters namely, average hop count, average packet delay, and link utilization with Exponential session traffic source while varying number of wavelengths (16, 32, 48, and 64) in WRONs (Wavelength Routed Optical networks) having 25, 50, and 100 nodes. It is observed that average hop count is independent of the number of wavelengths and gets its minimum with 100 nodes. Minimum average packet delay has been noted with lesser wavelength numbers and number of nodes. With greater wavelength numbers packet delay increases and this is not appreciated. A reciprocal relation is observed in between average packet delay and link utilization, as link is utilized as efficient, the delay would be minimized consequently. This simulation study with these findings would definitely help to understand the behavior of network performance parameters for WRONs.
