I tired to implement this option but it doesn't works well. So i implement new logic on this.

Simply check is session is set in every main methods. Below code help you

In logout(define in controller)

function __construct()
{
    parent::__construct();
    ob_start(); # add this
}

public function logout()
{
    $this->load->driver('cache');
    $this->session->sess_destroy();
    $this->cache->clean();
    ob_clean();
    redirect('home'); # Login form or some other page         
}

In dashboard(Function)

public function home()
{
    $logged_in = $this->session->userdata('logged_in');
    if($logged_in != TRUE || empty($logged_in))
    {
        #user not logged in
        $this->session->set_flashdata('error', 'Session has Expired');
        redirect('user_logging'); # Login view
    }
    else
    {
        #user Logged in
        $this->load->view("viewname",$data);
    }
}

In Login(function)

$session = array(
    'username'  => $name,
    'logged_in' => TRUE
);

$this->session->set_userdata($session);
