SIP Signaling Implementations and Performance Enhancement over MANET: A Survey

Abstract

Abstract-The implementation of the Session InitiationProtocol (SIP)-based Voice over Internet Protocol (VoIP) and multimedia over MANET is still a challenging issue. Many routing factors affect the performance of SIP signaling and the voice Quality of Service (QoS). Node mobility in MANET causes dynamic changes to route calculations, topology, hop numbers, and the connectivity status between the correspondent nodes. SIP-based VoIP depends on the caller's registration, call initiation, and call termination processes. Therefore, the SIP signaling performance has an important role for the overall QoS of SIP-based VoIP applications for both IPv4 and IPv6 MANET. Different methods have been proposed to evaluate and benchmark the performance of the SIP signaling system. However, the efficiency of these methods vary and depend on the identified performance metrics and the implementation platforms. This survey examines the implementation of the SIP signaling system for VoIP applications over MANET and highlights the available performance enhancement methods.

The Influence of SIP Call Control Signalling on VoIP Quality of Experience

“…The growing use of SIP signalling in these services has led to creation of measurement methodology for SIP server performances [9], [10]. Many research activities have been directed to evaluation of various SIP performance metrics in different environments, e.g., Mobile Ad Hoc Network (MANET) [11], Long Term Evolution (LTE) [12], [13], IP Multimedia Subsystem (IMS) [14], Software Defined Network (SDN) [15]/ Network Function Virtualization (NFV) environment [16], [17].…”
