Description: pure aloha 和slotted aloha算法的 matlab代码。结果显示了两种算法吞吐量的对比，通过修改标签数也可以得出吞吐量的变化值。
纯ALOHA协议(Pure ALOHA)
当传输点有数据需要传送的时候，它会向立即向通讯频道传送。
接收点在收到数据后，会ACK传输点。
如果接收的数据有错误，接收点会向传输点发送NACK。
当网络上的两个传输点同时向频道传输数据的时候，会发生冲突，这种情况下，两个点都停止一段时间后，再次尝试传送。
因为有太多的传输冲突.-pure aloha and slotted aloha algorithm matlab code. The results show the comparison of the two algorithms throughput, by modifying the number of labels can also come to change the value of the throughput. Pure ALOHA protocol (Pure ALOHA) When the transfer point has data to transmit, when it would have to immediately transfer to the communications channel. After receiving the data reception point will ACK transmission points. If the received data has an error, the receiver sends NACK point to point transmission. After transmission when two points on the network at the same time to the channel to transmit data, it will conflict, in this case, two points are stopped for some time, try the transfer again. Because there are too many transmission conflict. Platform: |
