Abstract :
This work proposes algorithms to achieve full mesh connectivity in 4-fiber WDM self-healing rings (SHRs). The number of wavelengths required is calculated for both odd and even number of nodes on the ring and an optimal wavelength assignment algorithm is presented. This algorithm uses a simple matrix approach for calculating the wavelength assignment between nodes on the ring so as to achieve full mesh connectivity while avoiding any possible violation of the color clash constraint
