Abstract:
A method and an apparatus for managing a medium access slot in a wireless personal area network are provided to manage all beacon periods and all MAS(Media Access Slot) information by analyzing reservation information of a transmission beacon in a WPAN(Wireless Personal Area Network) on a super frame basis. A transmission data storage unit(301) stores a transmission beacon and transmission data. A transmission controller(302) reads the beacon from the transmission data storage unit according to a transmission beacon control signal, reads the transmission data from the transmission data storage unit according to a reception control signal, and transmits the data to a corresponding MAS. A transmission beacon analyzer(303) analyzes the transmission beacon from the transmission controller and detects reservation information. An MAS allocating unit(304) compares the reservation information with queue allocation information and allocates the allocation information to the MAS, when the allocated queue exists in the reservation information. A super frame controller(305) generates the transmission beacon control signal at a start timing of the super frame, generates the transmission and reception control signals at the start timing of the MAS, and delivers the controls signals to the transmission controller.

An optimum resource allocation method and system in a distributed MAC in a wireless personal area network are provided to prevent a waste of radio resources and thus enhance the efficiency of radio resources. A medium access client layer(110) determines a resource allocation method and the amount of resource to support a particular service and requests them. A physical layer(130) provides physical layer information including information about a reception state, a link quality state, and dynamic/static parameter. A medium access layer(120) allocates optimized resources of medium access control by using results obtained from functions of controlling a transmission speed, transmission power, interference and a transmission performance monitoring function which use the physical layer information and information about a frame transmission state provided from the physical layer according to a request of the medium access control client layer.
