![]() ![]() Taking into account the specific characteristics of the traffic in the mobile networks, it introduces a semi-dynamic approach based on a hybrid architecture using forwarding pointers without the load related to the dynamic models. This paper proposes a method for reducing the processing load and the signalization traffic generated by update and search location procedures compared to IS-41 standard. Given the limited bandwidth of the radio operator channel and the new time sensitive applications of third-generation systems, such an approach of mobility management is not convenient for the next generation mobile networks. From these standards, the location update and search procedures always imply interrogation of the HLR, even if the two mobile terminals that want to communicate are in the same location area. These two standards lean on a centralized architecture made up of home location registers (HLRs and visitor location registers (VLRs. Analytical results show that our mDPF outperforms the PMIPv6 and the other pointer forwarding schemes, in terms of reducing the total cost of signaling.ĭynamic Location and Forwarding Pointers for Mobility Managementĭirectory of Open Access Journals (Sweden)įull Text Available GSM and IS-41 are two mobility management standards widely used in second generation networks. Also, we analyse the binding update cost and packet delivery cost for route optimization, based on the mathematical analytic model. Based on these mobility-aware binding updates, the overhead of the packet delivery can be reduced. In other words, a handoff is aware of low mobility between the previously attached MAG (pMAG) and newly attached MAG (nMAG), and another handoff between the previously attached LMA (pLMA) and newly attached LMA (nLMA) is aware of high mobility. When the MN moves, this scheme can reduce the high signaling overhead for intra-handoff/inter-handoff, because the Local Mobility Anchor (LMA) and Mobile Access Gateway (MAG) are connected by pointer chains. ![]() The movement of a Mobile Node (MN) is classified as intra-domain and inter-domain handoff. ![]() In this paper, a mobility-aware Dual Pointer Forwarding scheme (mDPF) is applied in Proxy Mobile IPv6 (PMIPv6) networks. ![]() Cost-effective handoff scheme based on mobility-aware dual pointer forwarding in proxy mobile IPv6 networks. ![]()
