thanks for you reply, The problem is that connecting to ftp server taking time around 1 min and I have to upload files as soon as files created in a directory ( a file created in a directory whenever any incident occur and this is a whole day activity). So I thought instead of making connection to ftp server , upload file then close connection, I should establish connection to FTP initially and upload files continously.Below I am sharing a code (I did not share complete script. I only share relevent part of script) ******************************************** 
#!/bin/perl
use Net::SFTP::Foreign;
$sftp = Net::SFTP::Foreign->new($host, user => $user, port => $sport);
$sftp->die_on_error("Unable to establish SFTP connection");
print LOGFILE "Connected to $host \n";
##$appoutdir contain folder name where files resides.
## @ufiles variable contains name of files to be uploaded
foreach $ufile (@ufiles) {
    print LOGFILE "Uploading file " . $ufile . "\n";
    my($filename, $directories) = fileparse($ufile);
    $sftp->put("$appoutdir/$ufile", "$filename")
        or die "put failed: " . $sftp->error;
    move("$appoutdir/$filename","$apparchdir/$filename")
        or die "Moving to application processed directory failed: $!";
}
