Spatial collision resolution for packet-switched multiple-access wireless networks

A collision resolution scheme that accounts for the spatial aspects of co-channel interference is analyzed for multiple access packet communications with application in intelligent vehicle highway systems (IVHS). In wireless networks with interacting base stations, co-channel interference and collisions are diminished by using discontinuous transmissions and coordination: a base station is silenced (or power-controlled) by a neighboring station in order to improve the latter´s chance of successful transmission and decrease retransmission attempts. The performance of this spatial collision resolution scheme is studied with a priori knowledge packet capture probabilities
