Girolami M. Service discovery strategies for smart infrastructures. Technical report, 2013.
he goal of the Service Discovery is to find the services (or more generally, the resources) available on the network. The entrance of a new node in the network, may cause the provisioning of some services that an end-user or another node can discover and access according to a query expressed by the user. The description of the service is matched against the query and, eventually, a response is sent back to the user. In the case where more than one provider offers the same service, the user selects the best one according to some criteria. Many service discovery protocols have been already proposed for different application domains, most of them are suitable for wired and static network. This report describes some research challenges for the SD protocols in a mobile and dynamic scenario such as the Smart Infrastructures (SiS). The document introduces the SD problem, describes the SiS scenario and it concludes with some key aspects to be considered for a valuable SD protocol.
