Figure 8.8 The effect of response latency threshold α in the high mobility

case with normalized Doppler shift 0.06. (From Cai, Y. et al., IEEE Trans.

Vehicular Technol., PP(99). With permission.)

For an MCC user, the end-to-end throughput is decided by

the two connections separated by the split-TCP proxy. The effect

of the throughput of the connection between the split-TCP proxy

and the OTT service provider cloud,
