Method and apparatus to discover services and negotiate capabilities

A service discovery protocol may allow clients in a distributed computing environment to search for services. Service providers (or a listener agent) may respond to search requests by publishing or providing corresponding service advertisements or URIs to corresponding service advertisements. When a service provider responds to a discovery search request (either directly or through a listener agent), the provider may choose to publish a protected or an un-protected (complete) advertisement. A protected advertisement may include the set of information necessary to obtain a complete advertisement. Publishing a protected advertisement may force the client to obtain a valid credential from an authentication service before receiving the complete un-protected advertisement from the service provider. A complete un-protected advertisement is needed to create a message endpoint for accessing the service. Forcing clients to obtain a valid credential before receiving an advertisement may provide an additional level of security for the service provider. The security credential that may need to be obtained to receive the complete advertisement may also be used to construct a message gate to communicate with the service where the gate embeds the security credential in each message to the service.

Ontology-based service discovery system and method for ad hoc networks

An ontology-based ad hoc service discovery system includes a local service cache, a cache manager, a service description unit, a query processor, a service semantic inference unit and a node daemon. The local service cache restores a service ontology by collecting class information of all services advertised on an ad hoc network and stores the service ontology. The cache manager manages the local service cache and performs various preset operations on the cache. The service description unit stores a description of a corresponding service for use in initializing the local service cache. The query processor starts performing a semantic based service query protocol by receiving a service query from a user or an application program. The service semantic inference unit inspects whether the service query transmitted from a client is coincident with the content of the service. The node daemon performs a service cache synchronization protocol with neighboring nodes.

Distance-aware service discovery mechanism for determining the availability of remote services in wireless personal area networks

The present invention refers to a method for extending replicated service discovery information for determining the availability of requested remote services in a client / server-based network environment (400), wherein each of a multiplicity of client terminals (402) is connected to a single file and / or application server (404, 405) of a specific service provider via a wireless multi-hop network which is based on a store-and-forward messaging principle, i.e. a wireless Personal Area Network (PAN) based on Bluetooth technology. Thereby, said service discovery information is needed for a selection of the optimal service provider. The method comprises the steps of providing (S1) network distance information indicating the number of intermediate network nodes (406) acting as forwarding servers for accessing remotely accessible services between a client terminal (402) and a number of file and / or application servers (404, 405) within said wireless wireless multi-hop network and selecting (S2) a requested remote service running on a file and / or application server (404) of a specific service provider at a network distance in the physical proximity of the respective client terminal (402) which can be reached from said client terminal (402) with a minimum of forwarding delay based on said network distance information. According to one embodiment of the invention, service discovery information is dynamically adapted (S3) to information concerning varying resource availability and / or changing link characteristics within said wireless multi-hop network. In this connection, cached service discovery information is marked as active (S3a) only as long as a file and / or application server (404, 405) participates in a wireless communication session with the respective client terminal (402) and marked as inactive (S3b) after the connection between said server (404, 405) and the respective client terminal (402) is closed and a predefined time-out period has expired, thereby discarding (S3c) outdated service discovery information. According to a further embodiment, information indicating the usage of requested remote services is taken into account during the process of selecting (S2) a specific remote service.
