Abstract

An operation method of a first communication node constituting a vehicle network includes transitioning an operation state of the first communication node to a wake-up state when a preconfigured event is detected; determining whether a physical layer collision avoidance (PLCA) function is deactivated; in response to determining that the PLCA function is deactivated, generating a message including an indicator indicating that the PLCA function is deactivated; and transmitting the message.

Claims (24)

1. An operation method of a first communication node constituting a vehicle network, the operation method comprising:

transitioning an operation state of the first communication node to a wake-up state when a preconfigured event is detected;

determining whether a physical layer collision avoidance (PLCA) function is deactivated;

in response to determining that the PLCA function is deactivated, generating a message including an indicator indicating that the PLCA function is deactivated; and

transmitting the message,

wherein the message further includes range information of local identifiers (IDs) for determining a second communication node to transmit a second beacon, the range information includes a plurality of local IDs, and communication nodes having local IDs included in the plurality of local IDs are communication nodes for operating based on the PLCA function.

2. The operation method according to claim 1 , wherein the message is a network management (NM) message, and the indicator further indicates that the first communication node has not transmitted a first beacon.

3. The operation method according to claim 2 , wherein the indicator further indicates an operation status of the PLCA function as one of a disabled state, a resynchronization state, and a recovery state.

4. The operation method according to claim 1 , wherein in response to determining that the PLCA function is deactivated, the first communication node operates based on a carrier sense multi-access/collision detection (CSMA/CD) function.

5. The operation method according to claim 1 , wherein a communication node having a smallest local ID among the plurality of local IDs included in the range information is determined as the second communication node.

6. The operation method according to claim 1 , wherein the message further includes a master ID of a communication node operating as a master node, and the master ID indicates a source ID of the communication node operating as a current master node.

7. A first communication node constituting a vehicle network, the first communication node comprising:

a processor; and

a memory storing at least one instruction executable by the processor,

wherein when executed by the processor, the at least one instruction causes the processor to:

transition an operation state of the first communication node to a wake-up state when a preconfigured event is detected;

determine whether a physical layer collision avoidance (PLCA) function is deactivated;

in response to determining that the PLCA function is deactivated, generate a message including an indicator indicating that the PLCA function is deactivated; and

transmit the message,

wherein the message further includes range information of local identifiers (IDs) for determining a second communication node to transmit a second beacon, the range information includes a plurality of local IDs, and communication nodes having local IDs included in the plurality of local IDs are communication nodes for operating based on the PLCA function.

8. The first communication node according to claim 7 , wherein the message is a network management (NM) message, and the indicator further indicates that the first communication node has not transmitted a first beacon.

9. The first communication node according to claim 8 , wherein in response to determining that the PLCA function is deactivated, the first communication node operates based on a carrier sense multi-access/collision detection (CSMA/CD) function.

10. The first communication node according to claim 7 , wherein a communication node having a smallest local ID among the plurality of local IDs included in the range information is determined as the second communication node.

11. The first communication node according to claim 7 , wherein the message further includes a master ID of a communication node operating as a master node, and the master ID indicates a source ID of the communication node operating as a current master node.
