Just create a new variable that stores the version number of old DIO and then compare the version number value of new DIO with that variable.

//declare variable
static rpl_dio_t store_dio_verison;

//when old DIO arrives
dio.version = buffer[i++]
store_dio_verison = dio.version;

//when new dio arrives
dio.version = buffer[i++]
if (store_dio_verison == dio.version){
printf("DIO MATCH\n");}
else
printf("DIO NOT MATCH\n");
