1. A wireless transmission scheduling method that is a synchronous media access control (MAC) wireless transmission scheduling method optimized for a user datagram protocol (UDP) of a personal wireless network-based data transmission system, the method comprising:
setting, by a master station in a network, a superframe period, a beacon period, and a contention period;
calculating, by the master station, one or more slave transmission periods of one or more slave stations participating in the network and a master transmission period of the master station, wherein the master transmission period is shorter than any of the one or more slave transmission periods;
transmitting information regarding the slave transmission periods of the one or more slave stations to the one or more slave stations participating in the network;
transmitting, by the one or more slave stations, one or more data packets to the master station in the slave transmission periods using a user datagram protocol (UDP), without including an acknowledgement request to the master station, wherein the master station does not send an acknowledgement to the one or more slave stations after receiving any of the one or more data packets; and
transmitting, by the master station, a packet to the one or more slave stations in the master transmission period immediately following all of the one or more slave transmission periods and after receiving all of the one or more data packets from the one or more slave stations,
wherein each of the slave transmission periods is 16 ms and the master transmission period is 1 ms, in response to the superframe period being 20 ms, a sum of the beacon period and the contention period being 3 ms, and there being one master station and one slave station in the network.
