| Abstract | Multipoint communication is the efficient way of information transferral in view of
message throughput. Single-hop star WDM network is an interesting alternative among
WDM networks that can support multipoint communications. Currently, there are ongoing
developments on communication protocols for multipoint communications in single-hop star
WDM network. In this work, protocol I and protocol II, one concerns no transceiver-tuning
latency and another one concerns transceiver-tuning latency, are modified from various
protocols in order to support multipoint communications with the use of multiple receivers in
the network. They use a control channel for contention-based request process. Successful
request is the input to the data transmission slot allocation process. The allocation algorithm
that can be used for both protocols is presented. The influence on the capacity of multiple
receivers significantly enhance traffic performance of network implementing both protocols
under multipoint communications. In networks implementing both protocols, throughput
depends on the input to the allocation process. At high request rate, compared with number of
minislots in a control slot, where the successful request rate is decreased network throughput
is also decreased. Conclusively, in networks implementing protocol II where allocation
schedule is used, throughput of the network remains almost constant at high input load to
allocation process. It is an advantage over protocol I. |
