SeaMoX: A Seamless Mobility Management Scheme for Real-Time Multimedia Traffic Over Cellular Networks
Real-time multimedia applications are often deployed to provide critical information in situations such as news coverage of an event or an incident or an ambulance rushing to provide emergency care. Mobile cellular coverage and performance of a provider network varies both spatially and temporally and challenges the ability of the network to support uninterrupted network access and application continuity. We propose that inter-provider handoffs could alleviate this problem, given the recent proliferation of Dual SIM Dual Active (DSDA) devices and the possibility of Multi SIM Multi Active devices by configuring laptops with multiple wireless broadband connections. We propose an application QoS aware mobility management approach. The software implementation is termed as SeaMoX and based on SeaMo+, an earlier implementation. We use live video streaming as an example application and demonstrate the impact of network selection and handoff by examining the playback at the receiver, which uses an adaptive jitter buffer algorithm.
