The Internet has been designed to providie application services without quality guarantees. That explains why, in the last years several efforts have been made to endow Internet with QoS support. However, Internet QoS models have been designed before the existence of mobile Internet, so they do not consider the mobility issue. On the other hand, the current standard protocol for mobile Internet, Mobile IPv6 (MIPv6), reveals limitations in scenarios where users are constantly moving to another point of attachment. In these situations, MIPv6 introduces latency times that are not sustainable for applications with strict QoS requirements.
All things considered, reveal the emerging need to adapt the current standard mobility protocol and QoS models to satisfy today’s mobile user’s requirements.
