Abstract
In order to realize reliable Vehicular-to-Vehicular (V2V) communication systems, the recognition of radio propagation becomes an important basic technology. However, in the current wireless distributed network systems, it is difficult to accurately estimate the radio propagation characteristics because of the locality of the radio propagation due to surrounding buildings geographical features. In this paper, we construct a measurement-based radio environment database for V2V communication systems. The database first accumulates the received signal strength indicator (RSSI) related to the transmission/reception locations from V2V systems. By using the datasets, the average received power maps linked with transmitter and receiver locations are generated. We have performed measurement campaigns of V2V communications in the real environment to observe Received Signal Strength Indicator (RSSI) for the database construction. Our results show that the proposed method has higher accuracy of the radio propagation estimation than the conventional path loss model based estimation.
