Embodiment Construction

[0068]According to the following detailed description in conjunction with the accompanying drawings, the above-mentioned objectives, technical architecture, operations and advantages of the present invention will be more clearly understood.

[0069] Figure 8 is a diagram showing beacon scheduling information transmitted or received between devices in a virtual table form in a method of setting a beacon slot according to the present invention.

[0070] The wireless personal area network (WPAN) proposed by the present invention uses multiple superframes, each superframe has a beacon-only time period during which two or more beacons are transmitted. Each device sets a beacon transmission slot, ie, a beacon slot, in a beacon-only period located at the forefront of a superframe, in which it will transmit a beacon. In this case, each device will Figure 8 Beacon schedule information sent to or received from neighboring devices Figure 8 Beacon scheduling information in order to ...

Abstract

The present invention relates to a method in which each device sets my beacon slot using a beacon table in a WPAN, which uses superframes, each having a beacon-only period. In the method, beacon scheduling information, including information about neighbors' beacon slots and information about neighbors' neighbors' beacon slots, is received from neighbor devices. The beacon scheduling information is combined, and the neighbors' beacon slot information and the neighbors' neighbors' beacon slot information are input into a beacon table. The neighbors' beacon slots and the neighbors' neighbors' beacon slots are input into a field for BTTSs to be avoided in the beacon table. My beacon slot is set among beacon slots of the beacon-only period, except for the beacon slots input into the field for BTTSs to be avoided. Information about the set beacon slot is input into a field for my BTTS in the beacon table.

Description

technical field [0001] The present invention generally relates to a method of setting a beacon slot using a beacon table in a wireless personal area network (WPAN) and a WPAN device, and more particularly, to a method of setting a beacon slot and WPAN devices, wherein each device sets my beacon slot in consideration of beacon transmission slots of neighboring devices and devices adjacent to the neighboring device by generating a beacon table in the WPAN environment, thereby This enables reuse of beaconing slots of other devices without causing collisions between beacons. Background technique [0002] A wireless personal area network (hereinafter referred to as "WPAN") technology is one of the core technologies of a ubiquitous network in which people, computers, and objects are connected to each other through a single structure. A representative example of the application of the WPAN technology is a sensor network for combining an existing sensor network environment with an ...
