| Proxy Mobile IPv6 (PMIPv6) has been developed by the IETF as a network-based mobility management protocol to support the mobility of IP devices. Although several proposals have been made for localized routing optimization, they don't take into account handover management and localized routing simultaneously. In fact, the localized routing state is restored after handover, leading to packets loss and signaling overhead. On the other hand, Fast Handovers for PMIPv6 (F-PMIPv6) protocol has been designed to mainly solve the issues of the long handover delay and packets loss during handover. As a result, this thesis looks at improving the performance of PMIPv6 by using the benefits of F-PMIPv6 and adding the localized routing session handover to it. The improved protocol that is developed in this thesis is called Optimized Proxy Mobile IPv6 (OPMIPv6). The proposed protocol improves localized routing handover delay, signaling cost, and network utilization compared with F-PMIPv6 and PMIPv6. |
