| Outline of Final Research Achievements |
I proposed a spectrum assignment algorithm to satisfy service-oriented communication quality in a heterogeneous environment such as ZigBee/Wi-Fi coexistent network. In addition, I also proposed a control platform to realize the algorithm.
The proposed method assumes variety of service types such as multimedia traffic with strict delay constraint, data traffic with reliable delivery, and so on. It does not consider averaged quality, but achieves the required criterion of each service.
