Abstract

Lightweight communication protocols for wireless sensor networks (WSNs) are unfolding for machine to machine (M2M) communications and thus there is always going to be a possible conflict of interest on which protocol is best suited for any particular application. The two protocols of interest in this study are the message queue telemetry transport protocol for sensor network (MQTT-SN), a variant of message queue telemetry transport (MQTT) protocol and the constrained application protocol (CoAP). There have been studies that reveal that these protocols perform differently based on the underlying network conditions. CoAP experience lower delays than MQTT for higher packet loss and higher delays for lower packet loss. MQTT default communication via a broker is easier to scale compared to CoAP direct request-response paradigm. Although this is a huge advantage over CoAP, it presents the single point-of-failure problem. In this paper we propose an integration of MQTT-CoAP protocol using an abstraction layer that enables both MQTT-SN and CoAP protocol to be used in the same sensor node. Resources are managed by directly modifying sensor node configuration using CoAP protocol. Performance evaluation of these protocols under the integrated scenario shows acceptable levels of latency and energy consumption for internet of thing (IoT) operations.

Abstract

Penggunaan daya listrik secara efisien merupakan suatu hal yang perlu diperhatikan pada sebuah bangunan. Intensitas pemakaian daya listrik di Indonesia belum efisien karena masih banyak yang terbuang secara percuma seperti saat tidak ada orang di dalam ruangan lalu AC tetap menyala. Hal ini menyebabkan adanya konsumsi yang berlebih. Automasi sistem yang dapat mengurangi intensitas konsumsi daya listrik sangat diperlukan. Automasi sistem berfungsi untuk memonitoring dan mengontrol semua alat elektronik dalam ruangan untuk membantu mengurangi konsumsi daya listrik agar lebih efisien. Dalam proses automasi juga diperlukan proses klasifikasi data yang akan digunakan untuk mengukur apakah automasi sistem sudah berjalan secara efektif menurut standard IKE (intensitas konsumsi energi).
