Real-Time Emulation of Heterogeneous Wireless Networks with End-to-Edge Quality of Service Guarantees: The AROMA Testbed

EURASIP Journal on Wireless Communications and Networking

Table 2 Actions performed in the case study.

	Action	Comment	Time
1	User starts session	Interactive class, 64 kbps in downlink
2	User starts file download	FTP client/server	190 s
3	User modifies session throughput	Increase downlink bandwidth to 96 kbps	220 s
4	User modifies service class to streaming (same throughput)	Results in VHO due to the CRRM preferences for the streaming class	240 s
5	CRRM initiates VHO	Due to the loss of coverage in the current RAN	270 s
6	User stops file download	FTP client/server	310 s
7	User starts video streaming	Video 64 kbps and audio 24 kbps	380 s
8	CRRM initiates VHO	Due to CRRM preferences	440 s
9	Congestion in IR2 (current AR)	Additionally generated traffic	460 s
10	BB suggests reconfiguration	Results in VHO due to the congestion detection	540 s
11	User stops session	Resources are released
