A Survey of NETLMM in All-IP-based Wireless Networks

摘要

The recent advances in network-based localized mobility management (NETLMM) have facilitated the realization of All-IP based Wireless Networks. In this paper, the Proxy Mobile IPv6 (PMIPv6) actively standardized by the IETF NETLMM working group has been investigated. To explore the availability of network-based localized mobility management, the technological progress of PMIPv6 is discussed. Besides, the comparison of PMIPv6 with existing mobility management schemes is also explained. In addition, the procedure of signaling process and the simplified analysis of PMIPv6 in terms of the handoff latency are presented. Furthermore, practical applications and related open research challenges are illustrated in this paper. In addition, NETLMM in wireless mesh networks (WMNs) is discussed. Although NETLMM is not a totally new paradigm in IP study, it has been re-focused with the trend of convergence in All-IP based Wireless Networks to enhance the network performance in terms of the geographically specialized networks.
