These nodes often have 8-bit microcontrollers with small amounts of ROM and RAM. CoAP provides a request/response interaction model between application endpoints, supports built-in discovery of services and resources, and includes key concepts of the Web such as URIs and Internet media types.

The nodes in an wireless sensors network usually collect environment-related information and then send the data to a gateway, in order to be processed. There might be cases when the collected information leaks sensitive user data, so encrypting the communication would be a good practice is this cases.

In this way, all IEEE 802.15.4 nodes have access to the Internet. text/html 2021-12-06T22:23:08+03:00 http://ocw.cs.pub.ro/courses/iothings/proiecte/2017/influxdb?rev=1638822188&do=diff Volmer Mihai-Cristian - AAC Introduction A backend server for an IoT project is a server that collects data from sensors. It can also process the data and display it on a web page or provide ways to access the data. I have studied some of the available backend solutions for IoT projects. There are many options to choose from. However, each comes with its advantages and flaws. text/html 2021-12-06T22:22:08+03:00 http://ocw.cs.pub.ro/courses/iothings/proiecte/2017/iotdevs?rev=1638822128&do=diff Generic interface for IOT Developers they can use to monitor existing IOT enabled devices. If the device is configured to store it's output in an influxDB timeseries database (<https://elf.cs.pub.ro/wsn/wiki/proiecte/influxdb>) then this UI API can render it easily. Currently work in progress, we hope to release a version of it by the end of the semester text/html 2021-12-06T18:30:03+03:00 http://ocw.cs.pub.ro/courses/iothings/proiecte/2017/microsal?rev=1638808203&do=diff Nițu Adrian - SRIC Dental Implant With Contact Nano-Sensors for the Treatment of Xerostomia Microsal represents the collaboration of multiple faculties with the purpose to create a third generation micro-embedded device meant to alleviate symptoms of xerostomia and also collect patient data regarding the condition in an unobstrusive way. text/html 2021-12-06T22:21:16+03:00 http://ocw.cs.pub.ro/courses/iothings/proiecte/2017/sparrow?rev=1638822076&do=diff Iulia Manda - AAC Introduction CoAP is based on the wildly successful REST model: Servers make resources available under a URL, and clients access these resources using methods such as GET and PUT. It is intended for use in resource-constrained internet devices, such as WSN nodes.
