Abstract
A system and method for discovering services in an Internet of Things (IoT) environment are disclosed. The method may include providing service-feature information from a consumer app to a query service that is indicative of a service provided by a remotely located provider app and incorporating the service-feature information into resource records of an additional information section of a multicast domain name service (mDNS) message. The message is multicasted to other IoT devices, and a response message is received from at least one provider device. The additional information section of the response message is then analyzed to determine whether a service provided by the at least one provider device meets criteria defined by the service-feature information.
