  REST HTTP is the communication protocol of choice for software developers
today. In IoT systems with unreliable connectivity, however, a stateless
protocol like REST HTTP needs to send a request message multiple times, and it
only stops the retransmissions when an acknowledgement arrives at the sender.
In our previous work, we studied the usage of random linear network coding
(RLNC) for REST HTTP protocol to reducing the amount of unnecessarily
retransmissions. In this paper, we experimentally validate the study and
analyze REST HTTP with and without RLNC in a simple testbed in dynamic IoT
systems. The measurements show notable improvements in bandwidth utilization in
terms of reducing the retransmissions and delay when using network-coded REST
HTTP.
