Abstract
Provided is a method for transmitting beacon timing information from a transmission node in a wireless Local Area Network (LAN) mesh network. In the method, each of a plurality of nodes transmits a beacon signal with its unique offset within a beacon signal transmission time period and the transmission node periodically transmits beacon timing information including a first unique offset within the beacon signal transmission time period. The transmission node sets a second offset different from the first offset and transmits probe beacon timing information including the first offset and the second offset.
Claims14
A method of transmitting beacon timing information from a transmission node in a wireless Local Area Network (LAN) mesh network, the method comprising:
- transmitting, by each of a plurality of nodes, a beacon signal comprising a unique offset within a beacon signal transmission time period:
- periodically transmitting, by the transmission node, beacon timing information comprising a first unique offset within the beacon signal transmission time period;
- setting a second offset different from the first offset;
- and
- transmitting probe beacon timing information including the first offset and the second offset.
A method of receiving beacon timing information at a reception node in a wireless Local Area Network (LAN) mesh network, the method comprising:
- receiving the beacon timing information from a transmission node;
- detecting whether the received beacon timing information includes the Medium Access Control (MAC) address of the transmission node;
- if the received beacon timing information includes the Medium Access Control (MAC) address of the transmission node, detecting a first offset and a second offset that are the beacon timing information of the transmission node;
- checking if the second offset is the same as offsets of other transmission nodes;
- and
- if the second offset is the same as offsets of other transmission nodes, selecting the first offset to transmit a beacon timing information retransmission request.
A computer-readable recording medium storing a program to implement a method of transmitting beacon timing information from a transmission node in a wireless Local Area Network (LAN) mesh network, the method comprising:
- transmitting, by each of a plurality of nodes, a beacon signal comprising a unique offset within a beacon signal transmission time period:
- periodically transmitting, by the transmission node, beacon timing information comprising a first unique offset within the beacon signal transmission time period;
- setting a second offset different from the first offset;
- and
- transmitting probe beacon timing information including the first offset and the second offset.
A computer-readable recording medium storing a program to implement a method of receiving beacon timing information at a reception node in a wireless Local Area Network (LAN) mesh network, the method comprising:
- receiving the beacon timing information from a transmission node;
- detecting whether the received beacon timing information includes the Medium Access Control (MAC) address of the transmission node;
- if the received beacon timing information includes the Medium Access Control (MAC) address of the transmission node, detecting a first offset and a second offset that are the beacon timing information of the transmission node;
- checking if the second offset is the same as offsets of other transmission nodes;
- and
- if the second offset is the same as offsets of other transmission nodes, selecting the first offset to transmit a beacon timing information retransmission request.
