Abstract:

In this thesis we investigated the MQTT protocol, which results in being a valid solution for data transmission in an IoT solution. After having explored the main communication protocols, we focused on the main features of the MQTT that has been selected for our application. To this purpose, a MQTT broker has been created on Node-RED, while the remaining elements of the application have been developed on MATLAB. In particular, we exploited the MQTT and the Database toolboxes: the former is used to exchange data between two PCs through the MQTT protocol, while the latter is necessary to insert

Internet of things (IoT) är det överläggande området i denna rapport. IoT är ett väldigt intressant I nuläget och är snabbt växande. IoT kan beskrivas som ett nätverk av kommunicerande enheter som delar information och automatiserar eller försimplar uppgifter och därav ökar effektivitet och säkerhet. Området växer så pass fort att det förväntas vara 24 miljarder anslutna enheter vid år 2050, denna utökning leder i sin tur till ett ökat behov av förståelse för IoT protokollen som hanterar kommunikationen emellan enheterna.

A current challenge in the Internet of Things is the seeking after conceptual structures to connect the presumably billions of devices of innumerable forms and capabilities.

To allow computationally-constrained devices partaking in the network they have to be relieved from the burden of constant availability and extensive computatio

Several new and innovative lifestyles have been created and IoT becomes an indispensable part in human lives. Human can remotely control all devices using Internet at any time without location limitation. The data are collected, shared and analyzed for improving the life quality. In this thesis, we have designed a platform for providing IoT services using in a smart home. It is a low-cost and scalable

It not only enriches our life experiences but also enhances the convenience of many services. However, IoT devices are usually resource-limited and are deployed in many hostile environments. It incurs many potential attacks and threats. Agriculture is one of many fields that might benefit from the IoT technologies. In this thesis, we concern two main challenges： one is secure IoT framework and the other is a Green-House IoT system under this framework. In Taiwan

碩士<br>國立臺灣科技大學<br>資訊管理系<br>105<br>With the rapid advancements in Internet of Things (IoT), there are a lot of sensors deployed in each environment such as home, hospitals, and factories. By using these sensors, we can collect different kinds of data from the environment and analyze it later. However, these sensors which have functionality to connect Internet have become attacked targets by malicious hacker. Although the manufacturers release new version of firmware to resolve vulnerability for specific sensors, the administrator of sensors may ignore the importance of firmware update. As a res

Abstract:

In this thesis, we present our IoT platform developed by using open source technologies, following a flexible component approach. The platform architecture is divided into multiple layers providing the flexibility required in order to allow the integration of custom gateways and application servers. The proposed IoT platform supports Low Power Wide Area Networks (LPWAN) integration, such as LoRa, using a custom network server implementation. The network server supports uplink/downlink communications with a Message Queuing Telemetry Transport (MQTT) interface. This work may be applied i
