摘要： Disclosed herein is a multi-hop communication method based on distributed medium access control. In the multi-hop communication method based on distributed medium access control according to the present invention, a beacon frame which includes a first multi-hop information element is generated and transmitted to a neighboring device so as to search for a route to an external device which does not belong to a beacon group. A third multi-hop information element, which is generated based on a second multi-hop information element generated by the external device, is received from the neighboring device. A multi-hop route to the external device is set up in accordance with the third multi-hop information element, and data is transmitted to the external device. Therefore, a multi-hop route between devices in the extended beacon group can be efficiently set up.

摘要： Provided are an apparatus and method for managing a Medium Access Slot (MAS) in a Wireless Personal Area Network (WPAN). The apparatus includes a transmission data storage unit for storing a transmission beacon and transmission data; a transmission controller for reading and transferring the transmission beacon to a transmission beacon control signal, and reading the transmission data and transferring it at a corresponding MAS; a transmission beacon parser for parsing the transmission beacon; an MAS allocation unit for comparing the reservation information with queue allocation information of an allocation queue list to allocate MAS; and a superframe controller for generating the transmission beacon control signal, and generating the data transmission/reception control signal at the start time of the MAS allocated by the MAS allocation unit.
