Table 4.
Real field deployment results. 97.8% of vehicles were detected by two T-Sensor-v nodes and speed for 98.5% of them were calculated and delivered to the T-BS-com-v node.
| Conditions | Day time | Night time | ||
|---|---|---|---|---|
| Number of vehicles | (%) | Number of vehicles | (%) | |
| D0: 2 T-Sensor-v detecting | 189 − 3 = 186 | 98.4 | 223 − 6= 217 | 97.3 |
| D1: 1 or 2 T-Sensor-v can’t detect | 3 | 1.6 | 6 | 2.7 |
| C0: Successful end-to-end delivery | 186 − 2 = 184 | 98.9 | 217 − 4 = 213 | 98.2 |
| C4: T-Sink-v can’t receive one or two DETECT packet from T-Sensor-v | 2 | 1.1 | 4 | 1.8 |
