Abstract This paper presents several protocols without receiver collisions for WDM networks with tunable transmitter/tunable receiver architecture. These protocols include the simple non-receiver -collision protocol (called TS), the optimized scheduling (called ETS) and the modified ETS (called METS). Computer simulation indicates that these algorithms achieve extremely good performance. They are the efficient media access protocols for WDM networks. Moreover, the METS algorithm shows more outstanding performance with the increasing of the tuning time of optical device. It is with great practical value for the WDM network with arbitrary transceiver tuning latencies.
