In this paper, we propose two types of WDMA protocol for multi-wavelength optical networks that have a dedicated control channel. Protocol type I is designed for the case that the number of nimislots is less than the number of nodes (La<M). It is a modified version of ALOHA protocol. To improsve the perfomrance, it can provide more minislots by grouping of source nodes in a given time slot. Thus we can obtain better throughput since more minislots can redcue the probability of minislot collision. Protocol type II is designed for the case that the number of minislots is greater than or equal to the number of nodes (La${ge}$M). Proposed protocols employ the aging scheme to guarantee a fairness in the process of channel allocation. The perfomrance of proposed protocols are evaluated in terms of throughput and delay with variations in offered load. Simulation results show that the proposed protocols have superior performance to conventional protocols.
