要約(英語): We propose Timing Group Division (TGD) for faster IEEE 802.15.4 throughput. Our proposal method splits terminals in some groups. All terminals on each group have both Timing Group Division delay and CSMA/CA delay. Terminals avoid packets collision using two kind of delays so that the system becomes faster than using only CSMA/CA system. When terminals divided into 2 groups or more, we confirmed faster communication from our actual experiment result. Our proposal method was able to communicate faster than the method using only CSMA/CA according to 16 end-devices actual experiment results, and became faster more than 40% over. Furthermore, we propose autonomously grouping method using RSSI for the autonomous decentralized network. Our proposal method using RSSI was able to faster than the method using only CSMA/CA according to actual experiment results, and became faster more than 25% over. Thus, we establish autonomously grouping method for TGD by our proposal method.
