Patent ID: 8488545

Claim:
A method of channel allocation and access by vehicles in a Vehicular Ad Hoc Network (VANET) comprising the steps of: dividing a service area into a plurality of regions; associating with each region p non-overlapping radio channels grouped into n disjoint radio channel pools where each pool comprises k radio channels; each vehicle determining its location in a region; dynamically resolving channel conflicts between vehicles; and allocating a channel to each vehicle in a region; where each vehicle has a radio transmission range r, where r≧l=kw, where l is the length of a region, w is the width of a region and k is a constant; and where the transmission range of a vehicle is selected so that n ≥ 2 ⁢ ⌈ r kw ⌉ + 1 , where n is the quantity of disjoint radio channel pools, r is the radio transmission range, k is the quantity of vehicles, and w is width of a region.
