This paper presents network architecture options along with their service discovery mechanisms, enabling realtime interactive multimedia session applications using the Internet Engineering Task Force’s (IETF) standard Session Initiation Protocol (SIP) in MANET. Two SIP MANET networking architectures are presented, both with and without a SIP proxy/registrar service. Effectively integrated into ...

This document introduces the transport of call control User-to-User Information (UUI) using the Session Initiation Protocol (SIP) and develops several requirements for a new SIP mechanism. Some SIP sessions are established by or related to a non-SIP application. This application may have information that needs to be transported between the SIP User Agents during session establishment. In additi...

This document specifies the Diameter Session Initiation Protocol (SIP) application. This is a Diameter application that allows a Diameter client to request authentication and authorization information. This application is designed to be used in conjunction with SIP and provides a Diameter client co-located with a SIP server, with the ability to request the authentication of users and authorizat...

In many SIP deployments, SIP entities exist in the SIP signaling path between the originating and final terminating endpoints, which go beyond the definition of a SIP proxy, performing functions not defined in Standards Track RFCs. The only term for such devices provided in RFC 3261 is for a Back-to-Back User Agent (B2BUA), which is defined as the logical concatenation of a SIP User Agent Serve...

Wireless networks and the voice over Internet protocol (VoIP) have recently been widely adapted. VoIP services over Ad-hoc network can be accomplished by middleware embedded in mobile devices. In this study, we have implemented an intelligent VoIP system with embedded pseudo session initiation protocol (SIP) server in an Ad-hoc network. We employed the standard SIP protocol and integrated SIP p...

In Internet telephony, there must be a means by which new services are created and deployed rapidly. In the World Wide Web, the Common Gateway Interface (CGI) has served as popular means towards programming web services. Due to the similarities between the Session Initiation Protocol (SIP) and the Hyper Text Transfer Protocol (HTTP), CGI seems a good candidate for service creation in a SIP envi...

Session Initiation Protocol (SIP) is widely used for establishing multimedia sessions, and chosen as the signaling protocol in the 3GPP standards. It also attracts many attempts to deploy SIP in a Mobile Ad-hoc Network (MANET). However, traditional SIP end points rely on SIP servers to discover one another and exchange SIP messages, which becomes a challenge due to lack of such server-based com...

In recent years Voice over Internet Protocol (VoIP) has become a popular multimedia application over the Internet. At the same time critical security issues in VoIP have started to emerge. The Session Initiation Protocol (SIP) is a predominant signalling protocol for VoIP. It is used to establish, maintain and terminate VoIP calls, playing a crucial role in VoIP. This paper is aimed at developi...

Session Initiation Protocol, SIP, provides controlplane signaling for the IP networks. SIP enables initiating, modifying and terminating sessions for a user, while maintaining neutrality to physical media capabilities and using other protocols to negotiate these. SIP assumes that the transport layer is inherently unreliable and as such provides transport layer mechanisms. For target device disc...
