Study and evaluation of voice over IP signaling protocols performances on MIPv6 protocol in mobile 802.11 network: SIP and H.323

The world currently has a strong trend towards homogeneous wireless networks, thanks to the mobility service that they offer, unlike wired networks. However, in homogeneous wireless networks several limits are required, like the transition from one network to another. This transition was often accompanied by a short connection failure due to the change of IPv4 addresses. However, in the presence of real-time applications, this network change delay is not accepted. The MIPv6 solution mitigates this deficiency by maintaining the same IPv6 address when moving from one network to another. In this paper, we will study MIPv6, and we will evaluate the Voice over IP (VOIP) performance with its two SIP and H.323 architectures. The study will be performed in a homogeneous 802.11e network in the context of a horizontal handover taking into account the MIPv6 technology. The evaluation criteria are: the call set-up time, the end-to-end delay, the loss rate and the jitter.
