System and Method for supporting QoS(Quality of Service) in Ubiquitous Sensor Network

The invention according to whether each node in the mesh coordinator (Mesh Coordinator), QoS data necessary to synchronize the superframe is configured to organize the superframe containing the QoS (Quality of Service) data transmission-only region as a network QoS generating a beacon frame including whether to use information by broadcasting a beacon-only period of the superframe and, QoS data transmission, if necessary, priority is to generate a set QoS data frame transmission to the QoS data-only section of the superframe in the node ubiquitous sensor network consisting relates to a system and method for QoS, if the data is QoS needed a couple of breaks and general data can be secured and the improvement and reliability of data transmission quality, the priority of the QoS data even between a couple of QoS data for the most important data Chapter can be transmitted quickly and reliably. QoS, a beacon, a super-frame, priority ubiquitous
