PURPOSE: A system and a method of supporting service quality in a ubiquitous sensor network are provided to set RAP for only QoS data in a transferring frame used in the ubiquitous sensor network, thereby embodying an end-to-end QoS technique. CONSTITUTION: A sensor node(150,152,154,156,158) transmits a RAP request frame, including a RAP(Reservation based Access Period), between a BOP(Beacon Only Period) and a CAP(Contention Access Period) in a super frame structure of an end-to-end communication using a WiBEEM(Wireless Beacon-enabled Energy Efficient Mesh network) protocol. A master node(140) receives a RAP request frame from a sensor node. If permission for the RAP is granted, the master node transmits a RAP beacon frame to all lower nodes. |
