| Popis: | Two versions of channel access protocols are proposed for single-hop lightwave networks with a passive star topology. The target system is assumed to operate synchronously on a time-slotted structure with a dedicated control channel to make reservation for exchanging data packets. While data channels are slotted with respect to the packet size, the control channel is further divided into the minislots of smaller size. Depending on the relation between the number of minislots La and the number of nodes M two channel access protocols are presented: Protocol A for L a >Mand Protocol B for L a .M. Both protocols improve the network performance by reducing the probability of control-channel collision. To do this, Protocol A adopts a grouping strategy while Protocol B naturally reduces the probability of collision. By the aid of an aging scheme, access fairness are also provided among the network nodes. The proposed protocols are analytically evaluated using a probabilistic model. Then simulation results compare two protocols with the others in terms of network throughput and delay. |
