Enable multimedia mobility with IEEE 802.21

Mobile devices supporting multiple radio technologies are becoming mainstream in the market. These devices can experience vertical handovers between heterogeneous networks due to device mobility or multiple network coverage. Handover latency is critical to ensure session continuity and end user experience. This paper presents a solution using IEEE 802.21 to enable seamless mobility for data and video streaming sessions. The solution was implemented and evaluated using commercial wireless networks and mobile devices. Lab and field trial results show minimal handover delay and improved user experience.
