Mobility anchor point selection based on user mobility in HMIPv6 integrated with fast handover mechanism

Abstract

In the context of Hierarchical Mobile IPv6 integrated with Fast Handover mechanism, this paper proposes two MAP selection algorithms, both based on the classification of users depending on their mobility. Furthermore an enhancement of one of the two algorithms is presented, it introduces the concept of bufferization at MAP level. Extensive simulations have been performed to analyse and investigate algorithms results.

QoS-Aware MAP Selection Scheme Based on Average Handover Delay for Multimedia Services in Multi-level HMIPv6 Networks

“…But in HMIPv6 networks with single MAP, the capacity and reliability of the networks need to be improved [5] [6] [10]. To meet this requirement, Multi-level HMIPv6 (M-HMIPv6) networks [5][6][7][8][9] were proposed inside which there are multiple MAPs. And, these MAPs forms different levels according to the number of hops from them to the Access Router (AR).…”

“…In such circumstances, there exist more than one MAPs above the ARs, and it is essential for the MN to select an optimal MAP when it visits the ARs using MAP selection schemes. Several schemes have been proposed for MAP selection in M-HMIPv6 networks such as Distance-based MAP Selection (DMS) [2], Mobility-based MAP Selection (MMS) [8] [9], Adaptive MAP Selection (AMS) [6], mobile history-based MAP selection [12] and abstraction node based MAP selection schemes [7], etc.…”

Dynamic MAP Selection Scheme in HMIPv6 Network

“…Besides, most MNs select the furthest MAP with the distance-based selection algorithm, so that the overload condition becomes even more severe. To mitigate the bottleneck problem, multiple MAPs are proposed to be configured into the form of a multi-level hierarchy in the same site [2]- [4]. Within a hierarchy of MAPs, some efforts have been made towards selecting an appropriate MAP for MNs according to the moving speed of MN [3], [4].…”
