Optimizing Fast Handover for Mobile IPv6 with Dynamic Price

Fast handover for mobile IPv6 (FMIPv6) reduces the handover latency and packet loss during handover procedure by using tunneling and buffering mechanisms. However, when the arrival rate of fast handover sessions is high, the request for buffer and tunneling bandwidth may cause network congestion and performance degradation. Some fast handover sessions have to be dropped, hence the service quality and user´s satisfaction degree is decreased. In our paper, an extension to FMIPv6 is proposed to avoid the congestion and service degradation, in which dynamic pricing strategy is applied.
