ABSTRACT
Over the past few years, protocols, implementations, and optimal uses and the use of internet of things have grown
dramatically. Among the communication protocols, the COAP is the most distinctive one. The protocol, has the
ability of better and lighter performance in restricted resource networks and devices. There are a lot of
implementations about COAP each has its own features and supplies. So, selecting the factors having effects on
improvement of COAP protocol and also the implementation method suitable for the features of each of these
supplies is important. So, optimal communication protocol which reduces traffic load is highly important and is
now, of the main challenges in the IOT industry and smart houses which, in recent years, has attracted many
researchers’ attention. This study provides some features and an analytical comparison of many variables
influencing the optimal performance of COAP. The present study has been conducted to answer the main question
of the study: does the use of COAP have any effects on reducing energy consumption in the smart houses? The
study has been conducted in the Uromieh Culture House and while studying the effective factors or important
variables in improving the COAP performance, has tested the accuracy or inaccuracy of the hypotheses such as
the main hypothesis of the study that there is a meaningful and positive relationship between using the COAP
protocol and reducing energy consumption in organizations. Finally, a new approach will be introduced in this
research causing improvement in the COAP efficiency. Then, its performance will be analyzed regarding reducing
in energy consumption, delay in sending data, reducing memory and CPU consumption, the amount of
information transmitted in each communication, firmness in failure and technological innovation. The present
study aims at identifying the effect of using the COAP protocol on reducing energy consumption in the smart
houses, Uromieh Culture House and ranking the factors influencing the implementation of performance
improvement based on the smart houses. The paradigm of the present study is interpretive. In terms of purpose,
the present study is of applied kind, in terms of data collection is of pluralistic one, in terms of procedure is of field
and library one, in terms of data analysis method is a descriptive study and finally, in terms of time is a crosssectional one. The statistical sample of the present study’s statistical society includes 49 people of the staff of the
Uromieh Culture House who participate in the study as experts and professionals in IOT and new and emerging
technologies of the smart houses fields. The results of data analysis show that the most effective factor in
implementing the COAP protocol successfully on reducing energy consumption in the smart houses is to reduce
energy consumption and the innovative technology factor has the least effect on successful implementation of the
protocol.
