Abstract
The Session Initiation Protocol (SIP) is a signalling protocol for Internet con-ferencing, telephony, presence, event notification and instant messaging. Unfor-tunately, SIP cannot be used in Mobile Ad hoc Networks (MANETs) directly because it relies on centralised services which conflicts with the notion of decen-tralisation usually associated with MANETs. An analysis of the existing SIP architecture and their problems in MANETs leads to the conclusion that the problem of SIP in MANETs can be mapped to the more generic problem of Distributed Service Discovery (DSD). Based on a solution for DSD, the centralised part of the SIP infrastructure can be replaced by a distributed counterpart. In order to tackle the DSD problem different existing approaches are stud-ied. The fully distributed approach to DSD is found to be the most promising one. Analogously to MANET routing protocols, DSD using a fully distributed approach can be done in a reactive manner, in a proactive manner or using a
