“…The radio propagation model is a disk and two nodes can communicate if and only if they fall within a distance R of one another. The probability density functions of the PLD and ELD for this configuration are investigated in several studies [4][5][6][7][8][9][10][11][12][13][14][15] for different mobility models. In [4], a closed form expression for the pdf of the ELD is obtained assuming a constant velocity (CV) mobility model, where each node selects a random direction over [0, 2p) and moves with a predefined constant velocity [9].…”
