Integrating service discovery protocols with presence-based communications for ad hoc collaborative scenarios

This paper presents an approach for the integration of service discovery protocols with presence-based communication services. The goal is to be able to facilitate communications among third-party services in an ad hoc manner in particular for collaboration scenarios that occur in meeting rooms, face to face, or across enterprises. The presence protocol SIP/SIMPLE is extended to support descriptions of services for existing common service discovery formats like the IETF service location protocol (SLP).
