The dual-bus optical network with nonregenerative stations has become popular. In general, the nonregenerative station implementation is better than the regenerative station implementation in media access control delay, cost, and susceptibility of station failures, etc. In this paper, two novel cycle-based protocols, named as synchronous wavelength sharing protocol (SWSP) and synchronous wavelength reusing/sharing protocol (SWRP), are proposed for nonregenerative wavelength-division-multiplexing dual-bus networks. The simulation results show that the network throughput and delay of SWRP are better than those of SWSP, when the numbers of wavelengths and tunable receivers are both limited, and/or the network traffic load is heavy.
