Abstract: A multidrop network system includes N network devices. The N network devices include a master device and multiple slave devices, and each network device has an identification code as its own identification in the multidrop network system. The N network devices have N identification codes and obtain transmission opportunities in turn according to the N identification codes in each round of data transmission. Each network device performs a count operation to generate a current count value, and when the identification code of a network device is the same as the current count value, this network device obtains a transmission opportunity. After a device obtains the transmission opportunity, it determines whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon/defer the right to start transmitting in the remaining duration of the predetermined time slot.

Abstract: A multidrop network system includes N network devices. The N network devices includes M transmission-permissible devices including a master device and at least one slave device, wherein M is not greater than N. Each transmission-permissible device has at least one identification code as its identification in the multidrop network system, and the M transmission-permissible devices have at least N identification codes. The M transmission-permissible devices obtain transmission opportunities in turn according to their respective identification codes in each round of data transmission. A Kth device among the M transmission-permissible devices has multiple identification codes, and thus obtains multiple transmission opportunities in one round of data transmission.

Abstract: A multidrop network system includes N network devices including a master device and a plurality of slave devices. The N network devices synchronize their respective time zones in a synchronization phase, then jointly perform equalizer coefficient training in a training phase, and then obtain their respective transmission opportunities in turn in a data transmission phase. Each network device includes a channel equalizer trained in the training phase and used for processing data in the data transmission phase. In the training phase, the master device sends out a training notification to request the slave devices to enter the training phase; the master device performs the equalizer coefficient training after it transmits the training notification, and the slave devices perform the equalizer coefficient training after they receive the training notification. After the completion of the equalizer coefficient training, the master device sends out a beacon to start the data transmission phase.

Abstract: A method for a multidrop network system is provided. The method includes the following steps: transmitting, by a first node, a sleep request message to a second node; and determining, by the first node, whether to enter a sleep state from a wakeup state according to the condition in which the second node transmits a sleep acknowledge message in response to the sleep request message.
