A mobile multimedia content handoff scheme based on proxy mobile IPv6 for VR/AR

This paper proposes a novel mobile multimedia content handoff scheme for a content delivery network (CDN) based on proxy mobile IPv6 (PMIPv6). PMIPv6 is a network-based mobility management protocol. In PMIPv6, when a mobile node (MN) that is currently receiving content from one domain moves into neighboring domain, it can maintain its existing session seamlessly. However, when the MN moves continuously, the content delivery path may become long, potentially leading to heavy network traffic and degradation of the quality of service (QoS) through delay and jitter. The proposed handoff scheme (PMIPv6-CDN Handoff) selects an optimal content server as a mobile node (MN) moves in a handoff and receives content. This scheme offers several benefits such as routing path optimization and a reduced transmission delay. Therefore, it can be applied to virtual reality (VR) and augmented reality (AR) services, which are sensitive to transmission delay.
