A Qualitative Analysis of Secured Handover Management Schemes for Mobile IPv6 Enabled Networks

摘要

Development in wireless technologies permits IPv6 enabled handheld mobile devices to access the Internet ubiquitously. An IP-address is required to identify the mobile host on the Internet. Mobile IPv6 (MIPv6) scheme enables a mobile host to migrate from one subnet to another without changing its exiting IP-address. For IPv6 based mobility, Internet Engineering Task Force (IETF) proposed standard Mobile IPv6 as first mobility management scheme. It provides a powerful and flexible way to handle handover management. Standard MIPv6 is a host-based global mobility management scheme and endure from basic issues such as signaling overhead, handover latency and packet loss. Subsequently, IETF has standardized localized network-based Mobility Management schemes to overcome problems associated with global host-based mobility management schemes named as Proxy Mobile IPv6 (PMIPv6). It reduces handover latency and packet loss compared to host-based mobility management schemes considerably, yet, suffers from security issues. Later on, researchers proposed secured-PMIPv6 protocols for authentication of mobile as well as network devices within LMD. The paper reviews various handover management schemes for secure handover management. The performance of various schemes qualitatively investigated on vital parameters such as authentication cost, signaling cost, packetloss etc.
