Exploring Service Discovery Protocols in IoT

The purpose of service discovery in an IoT ecosystem is for IoT devices to advertise and use the services of other devices in the network.

The purpose of DNS service discovery (DNS-SD) is to enable IoT devices to discover and utilize services available in the network using DNS-based mechanisms.

The three prominent service discovery protocols used for IoT devices are DNS service discovery (DNS-SD), Multicast domain name system (mDNS), and Simple service discovery protocol (part of UPnP).

<p>mDNS (Multicast domain name system) is used for service discovery in local networks without the need for a centralized DNS server. It allows devices to discover and communicate with each other using multicast DNS messages.</p> Signup and view all the answers
