Least Object Transfer Latency in the IoT with Small Congestion Window
Y.-J. Lee · 2019
Object transfer latency is a main factor composing the end-to-end latency in the Internet. The object transfer latency is affected by object size and transmission time by TCP congestion control mechanism. This paper aims to deal with the narrowband IoT (Internet of Things) environment which does not allow fast data retransmission due to the very small size of window. Our analytical model estimates the least latency when all the packet losses occur in the last congestion window during slow start. Our model can compute the object transfer latency when the packet loss rate, the initial congestion window size, the link bandwidth, and round trip time are given.
