COLLABORATION OF MQTT PROTOCOL AND VPN TUNELLING ON WEB-BASED SMART HOME MONITORING SYSTEM

Abstract

Internet of Things or commonly known as IoT is one of the smart technologies that combine the environment with devices through internet media. Interoperability is a product or system  characteristic,  whose  interface  is  truly  understood,  works  with  other  products  or systems. Therefore, a stable and lightweight data acquisition and data transmission mechanism is needed, one of which can be used is the Representational State Transfer (REST) mechanism that  uses  Unique  Resource  Identifiers  (URIs),  but  REST  is  still  unable  to  handle interoperability of each device, therefore an additional protocol is needed that can handle this, one of the most frequently used is Message Queue Telemetry Transport (MQTT). The use of REST and MQTT has weaknesses in security, data sent using REST and MQTT are able to be analyzed and retrieved data content using sniffing techniques. One technique that can be used to secure communication channels on the Internet of Things network is by utilizing a Virtual Private  Network  (VPN).  This  research  applies  OpenVPN  to  secure  communication  channels between  Gateway  IoT  and  Server.  Network  performance  is  measured  using  throughput  and packet loss parameters. The measurement results show a throughput value 1004 bps and packet loss 0%.
