                      <div>Dear Hassan,<br>
                        <br>
                      </div>
                      Thank you for prompt response. Actually, I can
                      define the scenario in following two points:<br>
                      <br>
                    </div>
                    1. As per application perspective, the producer
                    needs to send content whether it is needed or not by
                    consumers. Or there can be archiving of the content
                    later after its production.<br>
                  </div>
                  2. Due to requirements of the application, the network
                  has to adapt to push-based mechanism and might not be
                  limited to only pull-based mechanism where an interest
                  MUST be issued to retrieve content.<br>
                  <br>
                </div>
                What I've understood from your reply:<br>
                <br>
              </div>
              1. In vehicular environment, every node is performing as
              all in all. So do every node does in normal environment to
              be content router, producer and consumer, nothing
              different. But even in vehicular applications such as
              monitoring, a producer that wants to use the network to
              just accommodate its content may need to just push
              content.<br>
            </div>
            2. According to my sense, channel utilization is the task of
            layers below the "strategy layer" of NDN. Even for channel
            utilization, if content routers are aware of the application
            needs then they have to accommodate the content.<br>

                    <div style="font-family:arial,helvetica,sans-serif"><br>
                    </div>
                    <div style="font-family:arial,helvetica,sans-serif">In
                      Vehicular NDN research, mostly authors assume that
                      content routers are installed in each vehicle,
                      especially, when we say that no infrastructure
                      support is there such as RSU. So my point is that
                      almost every node/vehicle is performing as a
                      content router + provider + consumer role at
                      different instances under the given

                    <div style="font-family:arial,helvetica,sans-serif">Now,
                      if we talk about "Push" based communications, then
                      we might have a look at Pub/Sub mechanisms. If the
                      vehicles in any area are subscribed to the
                      specific type of data, then they don't need to
                      send interest(s) every time. On the other hands,
                      the producers start "pushing" the data into the
                      network. However, in naive NDN, this approach may
                      have its own consequences. Because, when you push,
                      then it will cost extra cost in terms of overhead
                      and additional copies of the packets and there
                      might be a case, that all the neighboring nodes do
                      not want to have that video content so why they
                      pay the cost of channel utilization for receiving
                      the data, they don't want or have any interest. </div>

                                  (vehicular/MANET), pull-based
                                  mechanism may not work properly.<br>

                                <div><br>
                                </div>
                                Scenario: In a highly dynamic
                                environment, the producer moving quickly
                                among content routers, capturing and
                                publishing video. So, producer can not
                                wait for an interest and want to push
                                the video content in-network before its
