A Secure and Efficient Energy Trading Model Using Blockchain for a 5G-Deployed Smart Community

Algorithm 4

Smart contract for energy trading.

Input: energy requested from EBEV;

Output: (1) ESEV gives energy to EBEV; (2) EBEV sends money to ESEV;

1: function EnergyTrading()

2:  if(EBEV available balanceEV’s charging cost)then

3:   returnfalse;

4:  if(ESEV available energyEV’s requested energy)then

5:   returnfalse;

6:  if(EBEV storageamount of energy purchased)then

7:   returnfalse;

8:  else

9:   Subtract amount from EBEV’s account balance;

10:   Add amount to ESEV account balance;

11:   Store transaction;

12:   Subtract energy from storage of ESEV;

13:   Add energy to storage of EBEV;

14:   Store transaction;

15  returnupdated information;
