The SIP signaling performance has a vital role for the overall QoS of SIP-based VoIP applications over MANET. The SIP end-to-end performance metrics have been defined in RFC 6076 to provide a standardized method for the performance evaluation of the SIP signaling system over different platforms. However, to our best acknowledge, the benchmarked values for these metrics have not been proposed yet. Therefore, in this paper, a novel Cross-Layer performance enhancement approach is proposed, implemented, and evaluated to improve the performance of the SIP signaling system over OLSR-based MANET by applying significant dynamic modifications for the routing parameters. The SIP performance metrics seek to accurately reflect the SIP signaling state and the required actions for the routing parameters. The implementation of the Cross-Layer OLSR approach has been successful effectively in reducing the total delays in the SIP processes, enhancing the signaling performance, and increasing the utilization level in the system bandwidth and routing processes.
