Fast dual-radio cross-layer handoffs in multi-hop infrastructure-mode 802.11 Wireless Networks for in-vehicle multimedia infotainment

Minimizing handoff latency and achieving near-zero packet loss is critical for delivering multimedia infotainment applications to fast-moving vehicles that are likely to encounter frequent handoffs. In this paper, we propose a dual-radio cross-layer handoff scheme for infrastructure-mode 802.11 Wireless Networks that achieve this goal. We present performance results of an implementation of our algorithm in a Linux-based on-board-unit prototype.
