TCP has traditionally been neglected as a transport-layer protocol for the Internet of Things
(IoT). However, recent trends and industry needs are favoring TCP presence in IoT
environments. In this article, we describe the main IoT scenarios where TCP will be used.
We then analyze the historically claimed issues of TCP in the IoT context. We argue that, in
contrast to generally accepted wisdom, most of those possible issues fall in one of the
following categories: i) are also found in well-accepted IoT end-to-end reliability …

TCP has traditionally been neglected as a transport-layer protocol for the Internet of Things
(IoT). However, recent trends and industry needs are favouring TCP presence in IoT
environments. In this paper, we first motivate and describe the main IoT scenarios where
TCP will be used. We then analyze the historically claimed issues of TCP in the IoT context.
We argue that, in contrast to generally accepted wisdom, most of those possible issues fall in
