+# Tutorial 2 - Wireless Network
+
+## Overview
+
+This tutorial will cover the use of a 3 node scenario in CORE. Then
+running a chat server on one node and a chat client on the other. The client will
+send a simple message and the server will log receipt of the message.
+
+## Files
+
+Below is the list of files used for this tutorial.
+
+* scenario.xml - 3 node CORE xml scenario file  (wireless)
+* scenario.py -  3 node CORE gRPC python script (wireless)
+
+## Running with the XML Scenario File
+
+This section will cover running this sample tutorial using the
+XML scenario file, leveraging an NS2 mobility file.
+
+* Make sure the **core-daemon** is running a terminal
+   ```shell
+   sudop core-daemon
+   ```
+* In another terminal run the GUI
+   ```shell
+   core-gui
+   ```
+* In the GUI menu bar select **File->Open...**
+* Navigate to and select this tutorials **scenario.xml** file
+* You can now click play to start the session

+     <img src="/static/tutorial2/wireless.png" width="75%">
+   </p>
+* Note that OSPF routing protocol is included in the scenario to provide routes to other nodes, as they are discovered
+* Double click node **n4** to open a terminal and ping node **n2**
+   ```shell
+   ping  -c 2 10.0.0.2
+   PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
+   64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=20.2 ms
+   64 bytes from 10.0.0.2: icmp_seq=2 ttl=63 time=20.2 ms
+
+   --- 10.0.0.2 ping statistics ---
+   2 packets transmitted, 2 received, 0% packet loss, time 1000ms
+   rtt min/avg/max/mdev = 20.168/20.173/20.178/0.005 ms
+   ```
+
+### Configuring Delay
+
+* Right click on the **wlan1** node and select **WLAN Config**, then set delay to 500000
+   <p align="center">
+     <img src="/static/tutorial2/wireless-config-delay.png" width="90%">
+   </p>
+* Using the open terminal for node **n4**, ping **n2** again, expect about 2 seconds delay
+   ```shell
+   ping -c 5 10.0.0.2
+   64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=2001 ms
+   64 bytes from 10.0.0.2: icmp_seq=2 ttl=63 time=2000 ms
+   64 bytes from 10.0.0.2: icmp_seq=3 ttl=63 time=2000 ms
+   64 bytes from 10.0.0.2: icmp_seq=4 ttl=63 time=2000 ms
+   64 bytes from 10.0.0.2: icmp_seq=5 ttl=63 time=2000 ms
+
+   --- 10.0.0.2 ping statistics ---
+   5 packets transmitted, 5 received, 0% packet loss, time 4024ms
+   rtt min/avg/max/mdev = 2000.176/2000.438/2001.166/0.376 ms, pipe 2
+   ```
+
+### Configure Loss
+
+* Right click on the **wlan1** node and select **WLAN Config**, set delay back to 5000 and loss to 10
+   <p align="center">
+     <img src="/static/tutorial2/wireless-configuration.png" width="90%">
+   </p>
+* Using the open terminal for node **n4**, ping **n2** again, expect to notice considerable loss
+    ```shell
+    ping  -c 10 10.0.0.2
+    PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
+    64 bytes from 10.0.0.2: icmp_seq=1 ttl=63 time=20.4 ms
+    64 bytes from 10.0.0.2: icmp_seq=2 ttl=63 time=20.5 ms
+    64 bytes from 10.0.0.2: icmp_seq=3 ttl=63 time=20.2 ms
+    64 bytes from 10.0.0.2: icmp_seq=4 ttl=63 time=20.8 ms
+    64 bytes from 10.0.0.2: icmp_seq=5 ttl=63 time=21.9 ms
+    64 bytes from 10.0.0.2: icmp_seq=8 ttl=63 time=22.7 ms
+    64 bytes from 10.0.0.2: icmp_seq=9 ttl=63 time=22.4 ms
+    64 bytes from 10.0.0.2: icmp_seq=10 ttl=63 time=20.3 ms
+
+    --- 10.0.0.2 ping statistics ---
+    10 packets transmitted, 8 received, 20% packet loss, time 9064ms
+    rtt min/avg/max/mdev = 20.188/21.143/22.717/0.967 ms
+    ```
+* Make sure to set loss back to 0 when done
+
+## Running with the gRPC Python Script
+
+This section will cover running this sample tutorial using the
+gRPC python script and providing mobility over the gRPC interface.
+
+* Make sure the **core-daemon** is running a terminal
+   ```shell
+   sudop core-daemon
+   ```
+* In another terminal run the GUI
+   ```shell
+   core-gui
+   ```
+* From another terminal run the **scenario.py** script
+   ```shell
+   /opt/core/venv/bin/python scenario.py
+   ```
+* In the GUI dialog box select the session and click connect
+* You will now have joined the already running scenario
+
+<p align="center">
+  <img src="/static/tutorial2/wireless.png" width="90%">
+</p>
+
+## Running Software
+
+We will now leverage the installed Chat App software to stand up a server and client
+within the nodes of our scenario. You can use the bases of the running scenario from
+either **scenario.xml** or the **scenario.py** gRPC script.
+
+* In the GUI double click on node **n4**, this will bring up a terminal for this node
+* In the **n4** terminal, run the server
+   ```shell
+   export PATH=$PATH:/usr/local/bin
+   chatapp-server
+   ```
+* In the GUI double click on node **n2**, this will bring up a terminal for this node
+* In the **n2** terminal, run the client
+   ```shell
+   export PATH=$PATH:/usr/local/bin
+   chatapp-client -a 10.0.0.4
+   ```
+* This will result in **n2** connecting to the server
+* In the **n2** terminal, type a message at the client prompt
+   ```shell
+   >>hello world
+   ```
+* Observe that text typed at client then appears in the terminal of **n4**
+   ```shell
+   chat server listening on: :9001
+   [server] 10.0.0.2:53684 joining
+   [10.0.0.2:53684] hello world
+   ```

+
+## Running with the gRPC Script
+
+This section covers using a gRPC script to create and provide scenario movement.
+
+* Make sure the **core-daemon** is running a terminal
+   ```shell
+   sudop core-daemon
+   ```
+* From another terminal run the **scenario.py** script
+   ```shell
+   /opt/core/venv/bin/python scenario.py
+   ```
+* In another terminal run the GUI
+    ```shell
+    core-gui
+    ```
+* In the GUI dialog box select the session and click connect
+* You will now have joined the already running scenario
+* In the terminal running the **scenario.py**, hit a key to start motion
+   <p align="center">
+     <img src="/static/tutorial3/mobility-script.png" width="80%" >
+   </p>
+* Observe the link between **n3** and **n4** is shown and then as motion continues the link breaks

+     <img src="/static/tutorial3/motion_continued_breaks_link.png" width="80%" >
+   </p>
+
+## Running the Chat App Software
+
+This section covers using one of the above 2 scenarios to run software within
+the nodes.
+
+* In the GUI double click on **n4**, this will bring up a terminal for this node
+* in the **n4** terminal, run the server
+   ```shell
+   export PATH=$PATH:/usr/local/bin
+   chatapp-server
+   ```
+* In the GUI double click on **n2**, this will bring up a terminal for this node
+* In the **n2** terminal, run the client
+   ```shell
+   export PATH=$PATH:/usr/local/bin
+   chatapp-client -a 10.0.0.4
+   ```
+* This will result in **n2** connecting to the server
+* In the **n2** terminal, type a message at the client prompt and hit enter
+   ```shell
+   >>hello world
+   ```
+* Observe that text typed at client then appears in the server terminal
+   ```shell
+   chat server listening on: :9001
+   [server] 10.0.0.2:53684 joining
+   [10.0.0.2:53684] hello world
+   ```
+
+## Running Mobility from a Node
+
+This section provides an example for running a script within a node, that
+leverages a control network in CORE for issuing mobility using the gRPC
+API.
+
+* Edit the following line in **/etc/core/core.conf**
+   ```shell
+   grpcaddress = 0.0.0.0
+   ```
+* Start the scenario from the **scenario.xml**
+* From the GUI open **Session -> Options** and set **Control Network** to **172.16.0.0/24**
+* Click to play the scenario
+* Double click on **n2** to get a terminal window
+* From the terminal window for **n2**, run the script
+   ```shell
+   /opt/core/venv/bin/python move-node2.py
+   ```
+* Observe that node 2 moves and continues to move
