Comparing the outage probability. This figure illustrates the comparison between the proposed system outage probability versus the maximal ratio combining system at distance from 0 to 200 m. In each hop, the proposed system selects the best route only, while diversity schemes multi-hop system uses the maximal ratio combining which select all routes in order to decrease the outage probability. The outage probability in clear weather is around 60% at 100 m for both systems with a noticeable advantage for diversity schemes multi-hop system (i.e., 57% for diversity system versus 68% for the proposed system). In contrast, for different weather conditions such as heavy fog, the outage for the two systems is nearly the same (i.e., both have 52% outage for 50 m distance)
