. 2021 Jul 28;21(15):5120. doi: 10.3390/s21155120

Algorithm 1: Finding the nearest vehicle with which to communicate

Input: Number of vehicles in the transmission area (V), emergency vehicle position, emergency vheicle transmisson power (P_E), channel fade coefficient (h_EVN), different interfence devices, interference transmission power (P_D, P_C, P_vi), interference channel fade coefficient (h_DVN, h_CVN, h_VVN), channel noise (N), the required outage probability (p_outEVN), and the path loss exponent (α)
Output: Finding the nearest vehicle with which to communicate
1: Establish the required p_outEVN
2: for different values of P_E, P_D, P_C, P_v, h_EVN, h_DVN, h_CVN, h_VVN, α do
3: Determine the nearest receiving vehicle using

d_{E V N m a x} = {(\frac{- S I N R_{t h} (P_{D} {| h_{D V N} |}^{2} P L_{D V N} + P_{C} {| h_{C V N} |}^{2} P L_{C V N} + P_{v i} {| h_{V V N} |}^{2} P L_{V V N} + N)}{P_{E} {| h_{E V N} |}^{2} P L_{O} l n (1 - p_{o u t E V N})})}^{- \frac{1}{α}}

4: Send emergency message to the nearest receiver directly
5: end for
