The most prominent protocols for data transfer in internet of things (IoT) are
message queuing telemetry transport (MQTT) and constrained application
protocol (CoAP). The existing clients from both sides are unable to
communicate directly because of the packet’s header structure difference in
application and transport layer. In response, this paper aims to develop a
bidirectional conversion server used to translate the specified messaging
protocol interchangeably in the OpenFlow network and transmit the
converted packet from both sides. The conversion server integrated the
MQTT subscriber and CoAP POST object for converting the MQTT
message into CoAP data. Similarly, the CoAP-MQTT translation was
processed by CoAP GET and MQTT publisher object. The research was
evaluated by analysing the round trip time (RTT) value, conversion delay,
and power consumption. The RTT value for MQTT-CoAP required 0.5 s
while the CoAP-MQTT was accumulated in 0.1 s for single-packet
transmission. In addition, the SDN controller and the conversion server only
consumed less than 1% central processing unit (CPU) usage during the
experiment. The result indicated that the proposed conversion server could
handle the translation even though there was an overwhelming request from
the clients.
