The distribution of boundary collision pairs. The numbers on the horizontal axis indicate how many boundary collision pairs exist on a resource block. The vertical axis represents the number of each case which occurred during the simulation. Two geo-based algorithms, namely random geo-based resource selection algorithm (RGRSA) and sensing geo-based resource selection algorithm (SGRSA) in contribution [9] and [14], respectively, are selected as comparison schemes. The proposed enhanced geo-based resource selection algorithm (EGRSA) is indicated in yellow. The RGRSA and the SGRSA are indicated in orange and blue, respectively
