Internet of Things (IoT) seeks to broaden the scope of the Internet by
connecting a variety of devices that can communicate with the Internet. Transport services for IoT are crucial in enabling the applications to communicate reliably
and in a timely manner while making efficient and fair use of the potentially
scarce network resources. The communication with IoT devices is often implemented
using HyperText Transfer Protocol (HTTP) or a specifically designed
protocol such as Constrained Application Protocol (CoAP) that is a specialized
web transfer protocol for constrained nodes and networks. In this paper we discuss
various options for modifying or adapting HTTP to offer better transport
service for IoT environments. We consider HTTP, SPDY that has been developed
to speed up HTTP in general, IoT-HTTP and IoT-SPDY that are adaptations of
HTTP and SPDY for IoT, and CoAP as transport services for IoT and experimentally
evaluate their performance. The results of our experiments show that
CoAP has the lowest object download times and the least number of bytes transferred
compared to the other four transport services. IoT-HTTP and IoT-SPDY
have around 50% shorter object download times and smaller number of bytes
transferred compared to HTTP and SPDY.
