Method of transmission rate decision based on frame aggregation using data collision and System for performing the same

摘要

The present invention relates to a frame aggregation-based transmission rate determination method using data collision, wherein the sensor node transmits a beacon to a sink node; B) the sensor node transmits data to the sink node during a beacon interval (BI); A C step of the sink node calculating a beacon interval value after the data transmission step; A step D for the sink node to measure the number of packet collisions occurring during the beacon interval five times; An E step of the sink node calculating a packet collision rate value using the packet collision frequency; An F step of determining a number of frames of a MAC layer transmitted by the sensor node using the beacon interval value calculated in step C and the packet collision ratio value calculated in step E; And a control unit. In addition, the present invention provides a sensor node comprising: a plurality of sensor nodes for collecting and transmitting external data; And a sink node receiving data from the sensor node; Wherein the sensor node includes a data unit including a physical layer (PHY layer) and a MAC layer for transmitting data, and the data unit includes a plurality of frames of the MAC layer in a frame of the physical layer So that it can be inserted.
