Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0044] Picture 9 It is a schematic flowchart showing the message and flow of a distributed network according to the first embodiment of the present invention. in Picture 9 Suppose that the master station (master station 1) of piconet A recognizes the piconet to which the desired base station to be found belongs through remote scanning. This remote scan is defined in the IEEE 802.15.3 standard.

[0045] First, in step S100, the master station 1 sends the distributed network request frame to the slave stations belonging to the piconet A and the piconet B at the same time. In step S110, the slave station that has received the distributed network request frame relays the distributed network request frame to the master station of the piconet B (master station 2). The distributed network request frame may include information such as the start time and period of the sup...

Abstract

The present invention relates to a method of implementing a decentralized network among multiple piconets using different frequencies in a Wireless Personal Area Network (WPAN). In the distributed network implementation method of the present invention, the master station of the first piconet sends a distributed network request to the shared slave station, and the shared slave station switches its frequency to the frequency of the second piconet network, and the distributed network The network request is relayed to the master station of the second piconet. The master station of the second piconet sends a scatternet approval to the common slave station. The common slave station switches frequency to the frequency of the first piconet, relays the scatternet approval to the master station of the first piconet, and the first piconet and the second piconet The master station of the piconet allocates mutually non-overlapping resources to the shared slave station. The common slave station switches frequency and relays data between the first piconet and the second piconet while synchronizing with both the first piconet and the second piconet using the allocated resources .

Description

Technical field [0001] The present invention generally relates to an IEEE 802.15.3 communication system that complies with the high-speed wireless personal area network standard, and more specifically relates to a method of implementing a scatternet for data transmission between piconets using different frequencies. Background technique [0002] The IEEE 802.15 working group established a standard for a wireless personal area network (WPAN), which is composed of mobile computer devices in a network (such as a PAN) implemented within a short distance. In recent years, efforts have been made to apply WPAN to home automation, remote control, ubiquitous sensor network, etc. [0003] Specifically, the IEEE 802.15.3 standard that has recently been completed is designated as high-speed WPAN (HR-WPAN), and it aims to realize a wireless communication network suitable for applications requiring a high data rate of 55 Mbps or higher. The IEEE 802.15.3 standard has the following characterist...
