Sergei,

Sorry for my delayed answer. The radio was IEEE 802.11 wavelan. In fact the
routing protocol was included in the level 2 protocol as an additional layer
in order to make IEEE 802.11 MAC to operate as HIPERLAN1 MAC
intra-forwarding layer. Some experiments were performed outdoor between
moving cars.
