Team 2013 Weekly Presentation #1 9/29/2019 - 10/05/2019

Weekly Progress ● Submitted Problem Statement on September 30th Beginning research on IoT testing/verification (in general terms) ●

The Problem ● Many IoT devices - need one way to test them ● Focus on HVAC ● System composed of ○ Machine - sensors push data to cloud through a gateway ○ Cloud - stores/analyzes data ○ Interface - usually mobile/web app to monitor data and/or control machine (actuators) Carrier Wi-Fi thermostat

Simple IoT Architecture

Heat Pump Types of HVAC Systems ● Heat Pump Rooftop Unit ● ● Water Source Heat Pump ● Packaged HVAC ● Split System HVAC Ductless System ●

Technologies Used in IoT ● RFID - uses radio frequency NFC - mostly used in mobile devices ● ● Bluetooth - close range wireless comm RFID ● Z-Wave - low power RF tech. Mainly used for home automation (lamp controlling, etc.) Wi-Fi - most common in IoT ● ● 2G/3G/4G/5G ● Others

IOT Management ● Device Management -Being able to adopt a standardized device management protocol/services will enable better device security, interoperability, and power/processing capabilities. ● Device Connectivity and Management -For IOT there are many options in terms of communication and connectivity. -Each communication protocol has varying ranges in terms of power consumption, bandwidth and latency, and security. All of which needs to be considered when choosing a suitable protocol for a particular IOT application.

Goals of IoT Verification/Testing ● Performance - speed of data transfer Scalability/Reliability - how scalable and reliable is the system ● ● Cost/time reduction ● Automation - testing process should do most of the work ● Compatibility - process should apply to many different devices

Types of IoT Testing ● Usability: How useful is the device? Can it provide the necessary data? Compatibility: Many devices, different hardware/software ● ● Reliability and scalability: Simulations to ensure reliability and scalability of device. Can we add more devices to the system? ● Data integrity: Lots of data, needs to be verified Security: Many users accessing lots of data, need authentication (passwords, ● encryption, etc.) ● Performance: Speed of acquiring/transferring data

Gray Box Testing ● Probably used in this project Develop test cases for a system that is only partially understood ● ○ Might know how the systems interact with each other, but not sure how each system works ○ Info, documentation, source code are limited

Challenges to Consider ● Complexity of hardware-network-software mesh Device interaction in real time ● ○ security, backward compatibility, upgrade issues ● Real-time data testing Many different UIs ● ● Network availability/strength/etc

What to do next ● Figure out: Technologies that Carrier uses for IoT ○ ○ How these systems interact with each other What tools can be provided ○ ● Ask for a model ● Find out which verification goals we should focus on Define a reference IoT architecture (focus on HVAC) ● ● Get answers to questions in problem statement ● Ultimately, find out what exactly needs to be delivered
