Tuning latency and scheduling latency are two major overheads when designing medium access control (MAC) protocols for single hop passive star-coupled WDM optical network. Some schemes proposed so far has considered these two overheads, however, they cannot remove these two overheads completely, especially the overhead caused by receiver. To reduce the negative impact of tuning latency and scheduling latency, we propose one channel assignment algorithm and one message scheduling algorithm in this paper. The improvement of our proposed schemes in terms of average message delay can be observed from the results obtained by simulation.
