Information Raining for Mobile Hotspots in 4G Wireless Networks
نویسنده
چکیده
A system architecture is proposed to support mobile hotspots. The proposed architecture uses multiple repeaters to relay signals from access routers to vehicles and vice versa. Erasure codes are used in the access router to decompose data packets into fixed size fragments. The fragments are then disseminated to the vehicle through the repeaters. The original packet is reconstructed in the vehicle station by consolidating the detected fragments. We call this approach information raining and show how it can be used to provide high throughput to highly mobile users. We show that the proposed system does not need handoff. We also design a new mobile IP architecture that can be applied to batches of IP addresses.
