We present a vehicular communication protocol, GeoCode, capable of containing broadcast transmissions within a confined region. The crux of the protocol is a modified directed diffusion policy, which is used to generate multiple paths within an ellipse, these paths may intersect each other at intermediate nodes which use network coding to maximize the throughput. A comparison with traditional multi-path routing algorithms, which deliver node-disjoint and non coding-aware solutions, reveals that GeoCode is able to achieve the same throughput using only 1/3 of the transmission area, thus mitigating the interference and reducing the overall energy consumption.
