In this paper we look at the signaling for session mobility using the Session Initiation Protocol (SIP) and the Session Description Protocol (SDP). Bearing in mind that perceived voice quality is sensitive mostly to delay variation (also called jitter), we work on bounding that value for providing a better voice Quality of Service over Wireless LAN (WLAN). For mobility we use a hybrid SIP-MIP stack. The basic idea is to combine the strengths of MIP for doing fast handovers and the strengths of SIP for powerful session adaptation capabilities. Numerical calculation figures as well as real implementation results are provided. It can be observed that the session update cycle during mobility can be modified in such a way that session delay variation bounds achieved are quite low and there are almost no spikes. We use composite performance metrics that we defined in previous work to analyze the correlation between the data patterns for session signaling delay in the classical case and our proposed case to better highlight the achieved performance delta.

“…Where Bianchi's parameterization of the model concerned the Frequency-Hopping Spread Spectrum (FHSS) method, others [30,14,23] have applied the PHY/MAC parameters of the IEEE 802.11 b-, g-and astandard, respectively. In more recent work [26] a detailed description is given on the use of the 802.11 a/b/e/g/n standards and a mixture thereof in the context of multi-service QoS guarantees. For a detailed description of the PHY/MAC level aspects we refer to [26], of which the 802.11 MAC parameterization details are used as a basis for the analytic model presented below.…”

Section 2.1 forms a brief introduction on modelling the IEEE 802.11 MAC aspects, followed by the analytic model in Section 2.2 that translates the MAC/IP/TCP-level dynamics into an explicit expression of effective service time at the application-layer.…”

“…Under those circumstances stations may operate on different transmission rates or even on a different standard to support higher data-rates or prioritization techniques. In this context we refer to [26] for a detailed description on the use of the 802.11 a/b/e/g/n standards and a mixture thereof with the influence of backward compatibility.…”
