PMIPv6-HC: Handover Mechanism for Reducing Handover Delay and Packet Loss in NGWN

Next generation wireless networks will consist of inter-working heterogeneous wireless access technologies that will be integrated over an IP-based infrastructure to provide network access ubiquity. In such a networking environment mobility particularly vertical handover between the heterogeneous wireless networks has to be supported. However, it is challenging to coordinate vertical handover within this diverse environment to ensure better handover performance in terms of handover delay and packet loss. Consequently, this paper proposes the idea of employing a handover coordinator between the heterogeneous networks that are affected in the handover process. The main idea is that dynamically coordinating handover procedures ahead of time among the affected networks will enhance overall handover performance.
