Beschreibung
Zusammenfassung:	The invention discloses a time sensitive transmission and bandwidth optimization utilization-based method used under an IEEE802.15.4 network environment, which comprises the following steps of: firstly, considering a time period Di of transmission data of different nodes and time ED (i) occupied by transmission; and secondly, allocating GTS for each node, reallocating GTS (UGTS) which is not usedin the last scheduling process by an effective method, and improving the GTS utilization rate so as to improve the bandwidth utilization rate. The method has the advantages of good performance in theprocess of transmitting time sensitive service and convenient implementation at a user terminal.
