| <h1>Network Simulator Cell</h1> |
| |
| <div class="article-style"> |
| <p>The built-in Eclipse MOSAIC Cell Simulator enables the applications to use cellular network communication. |
| The simulation of cellular communication in Eclipse MOSAIC consists of two parts:</p> |
| <ol> |
| <li>The Cellular Simulator itself and</li> |
| <li>The applications that can communicate over cellular networks in the Application Simulator</li> |
| </ol> |
| <p>These changes are done in a generic way, making the cellular simulator exchangeable. Users interested |
| in a different kind of simulation of cellular communication may use other simulators and develop |
| ambassadors connecting them to Eclipse MOSAIC.</p> |
| <p>The Cellular Simulator in the current state consists of three main modules:</p> |
| <ol> |
| <li>UplinkModule</li> |
| <li>GeocasterModule</li> |
| <li>DownlinkModule</li> |
| </ol> |
| <p>The Geocaster module simulates a mandatory component for ITS communication. It is inspired by |
| the several architectures from research projects as simTD or CONVERGE to enable ITS use cases over |
| cellular networks. It mainly takes over the task of an addressing and routing component with geographic |
| knowledge to support geo-addressing. However, it also supports regular topological addressing. |
| The Uplink and DownlinkModule are responsible for the transmission simulation. They account for the |
| aspects of transmission delays, packet losses and available data rates. In this context,Uplink and Downlink |
| always refer to the direction towards respectively from the Geocaster. For instance, a transmission |
| from an Internet-based server towards a vehicle would include an Uplink between the server and the |
| Geocaster and a Downlink between the Geocaster and the vehicle. While the Uplink direction only allows |
| point-to-point communication (Unicast), the Downlink supports point-to-point (Unicast) as well as |
| point-to-multipoint (Multicast).</p> |
| <h3 id="cellambassador-folder-structure">CellAmbassador folder structure</h3> |
| <p>The Eclipse MOSAIC Cell simulator can be configured via three distinct configuration files, which can be |
| found within the scenarios' folder structure:</p> |
| <pre><code class="language-FOLDER">└─ <scenario_name> |
| └─ cell |
| ├─ cell_config.json ................ Cell ambassador configuration file |
| ├─ network.json ..................... Network configuration file |
| └─ regions.json ..................... Regions configuration file |
| </code></pre> |
| <p>The network and regions configuration files are referenced in the cellular ambassador configuration |
| file.</p> |
| <h3 id="installation">Installation</h3> |
| <p>This simulator does not need to be installed. It is delivered as part of the Eclipse MOSAIC-installation package.</p> |
| <h3 id="configuration">Configuration</h3> |
| <p>We provide a cellular configuration file in the example scenarios of Tiergarten and Barnim. Please note |
| that in the default configuration of this scenario the Cellular Simulator is deactivated. To activate the |
| cellular simulator just enable the <code>cell</code> federate in the <code>scenario_config.json</code>:</p> |
| <pre><code class="language-json">"federates": { |
| ... |
| "cell": true, |
| ... |
| } |
| </code></pre> |
| <p>The central configuration for the cellular simulator in the file |
| <code><scenarioName>/cell/cell_config.json</code> could look like this:</p> |
| <pre><code class="language-Json">{ |
| "debugGeocasting": false, |
| "visualizeRegions": true, |
| "networkConfigurationFile": "network.json ", |
| "regionConfigurationFile": "regions.json " |
| } |
| </code></pre> |
| <p>The <code>visualizeRegions-option</code> from the <code>cell_config.json</code> is used to write a KML-file that visualizes the |
| used cell regions. Google Earth can be used to display it.</p> |
| <p>The configuration for the global network in the cellular simulator in the file |
| <code><scenarioName>/cell/network.json</code> could look like this:</p> |
| <pre><code class="language-json">{ |
| "globalNetwork": { |
| "uplink": { |
| "delay": { |
| "type": "ConstantDelay", |
| "delay": "100 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.0, |
| "maxRetries": 2 |
| }, |
| "capacity": 28000000 |
| }, |
| "downlink": { |
| "unicast": { |
| "delay": { |
| "type": "ConstantDelay", |
| "delay": "50 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.0, |
| "maxRetries": 2 |
| } |
| }, |
| "multicast": { |
| "delay": { |
| "type": "ConstantDelay", |
| "delay": "100 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.0 |
| }, |
| "usableCapacity": 0.6 |
| }, |
| "capacity": 42200000 |
| } |
| } |
| } |
| </code></pre> |
| <h3 id="server-configuration">Server configuration</h3> |
| <p>MOSAIC supports a type of simulation units, called servers. Traffic Management Centers are a specialised type of server. |
| What differentiates servers from other units is, that |
| they are treated as having no geographical location and instead are located “inside the internet.”. This concept omits prior shortcoming, |
| where one would have to configure RSU’s as servers.<br> |
| Servers are also configured in the <code>network.json</code> as follows:</p> |
| <pre><code class="language-json">{ |
| "globalNetwork": { |
| [...] |
| }, |
| "servers": { |
| { |
| "id": "TestServer", |
| "uplink": { |
| "delay": { |
| "type": "ConstantDelay", |
| "delay": "200 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.5, |
| "maxRetries": 2 |
| } |
| }, |
| "downlink": { |
| "unicast": { |
| "delay": { |
| "type": "SimpleRandomDelay", |
| "steps": 5, |
| "minDelay": "100 ms", |
| "maxDelay": "200 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.1, |
| "maxRetries": 2 |
| } |
| } |
| } |
| }, |
| { |
| [...] |
| } |
| } |
| } |
| </code></pre> |
| <p>Servers get their configuration for the delay and retransmission models from the <code>network.json</code> and the configuration for the |
| capacity-module has to be made from within an application, by activating the <code>CellModule</code> and properly setting the bit rates. |
| This could look as follows:</p> |
| <pre><code class="language-java"> getOs().getCellModule().enable( |
| new CellModuleConfiguration() |
| .maxUlBitrate(10000) |
| .maxDlBitrate(10000) |
| ); |
| </code></pre> |
| <p>For the CellAmbassador to be able to recognize servers, the <code>group</code>-field in the mapping must match the <code>id</code>-field in the <code>network.json</code>, |
| this also allows for multiple servers to utilize the same configuration. A <code>mapping_config.json</code> using the configuration from |
| above could look as follows:</p> |
| <pre><code class="language-json">{ |
| ..., |
| "tmcs": [ |
| { |
| "group": "TestServer", |
| "applications": [ "TestApplication" ], |
| "inductionLoops": [ ], |
| "laneAreaDetectors": [ ] |
| } |
| ], |
| "servers": [ |
| { |
| "group": "TestServer", |
| "applications": [ "TestApplication" ] |
| } |
| ], |
| ... |
| } |
| </code></pre> |
| <blockquote> |
| <p>Note that all bandwidths are given in bit per second and all delays in nanoseconds, unless explicitly defined differently. |
| Also, every json configuration goes through a minifier, so comments are allowed in the configuration files. An example |
| would be the comment before the <code>globalNetwork</code> option.</p> |
| </blockquote> |
| <h3 id="delay-regions">Delay regions</h3> |
| <p>Additionally, the user has the option to define regions with individual delays. This can be used to simulate |
| areas with bad reception, crowded areas etc.</p> |
| <p>The regions should be stored in <code><scenarioName>/cell/regions.json</code>. An |
| example definition for a single region called <code>Ernst-Reuter-Platz</code> could look like this:</p> |
| <pre><code class="language-Json">{ |
| "regions":[ |
| { |
| "id": "Ernst-Reuter-Platz", |
| "area": { |
| "nw": { "lon":13.3249, "lat":52.5131 }, |
| "se": { "lon":13.3273, "lat":52.5125 } |
| }, |
| "uplink": { |
| "delay": { |
| "type": "SimpleRandomDelay", |
| "steps": 4, |
| "minDelay": "50 ms", |
| "maxDelay": "200 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.8, |
| "maxRetries": 2 |
| }, |
| "capacity": 28000000 |
| }, |
| "downlink": { |
| "unicast": { |
| "delay": { |
| "type": "SimpleRandomDelay", |
| "steps": 3, |
| "minDelay": "100 ms", |
| "maxDelay": "200 ms" |
| }, |
| "transmission": { |
| "maxRetries": 2 |
| } |
| }, |
| "multicast": { |
| "delay": { |
| "type": "SimpleRandomDelay", |
| "steps": 3, |
| "minDelay": "120 ms", |
| "maxDelay": "220 ms" |
| }, |
| "transmission": { |
| "lossProbability": 0.8 |
| }, |
| "usableCapacity": 0.6 |
| }, |
| "capacity": 42200000 |
| } |
| } |
| ] |
| } |
| </code></pre> |
| <p>Note that <code>nw</code> represents the upper-left (north-west) point of the rectangle and <code>se</code> the lower-right (southeast). |
| For further information about the possible options, please refer to the Eclipse MOSAIC API documentation.</p> |
| <p>The actual configuration of the uplink and the downlink modules for each region exhibits the identical |
| format as configuration of the globalNetwork in the <code>network.json</code>.</p> |
| <p>When no regions are found, or if a node (a vehicle) is not within a specified region, the globalNetwork |
| defined in the <code>network.json</code>-File will be used as the delay model.</p> |
| <h3 id="transmission-simulation">Transmission simulation</h3> |
| <p>One of the most important feature of the cellular simulator is an estimation of the delay experienced |
| through the transport over the cellular network.</p> |
| <p>The cellular simulator offers various modes to estimate the delay of the transmissions. The type of |
| estimation is specified with by <code>delayType</code> for the uplink and downlink for each region. You may also refer to the |
| |
| <a href="https://www.eclipse.org/mosaic/docs/extending_mosaic/delay_models/">Delay-Chapter</a>.</p> |
| <ul> |
| <li><code>delay.type = ’ConstantDelay’</code>: The message is transmitted with the latency being exactly equal to delay.</li> |
| <li><code>delay.type = ’SimpleRandomDelay’</code>: The latency can assume different (randomly generated and uniformly distributed) values between |
| <code>minDelay</code> and <code>maxDelay</code>. The number of different values is determined by <code>steps</code>.</li> |
| <li><code>delay.type = ’GammaRandomDelay’</code>: A gamma distribution is used to estimate the latency, with $ \alpha $ = 2 and $ \beta $= 2. The |
| minimal delay <code>minDelay</code> is added to the result. The curve is fitted so that the maximum likelihood for the delay is exactly equal to |
| <code>expDelay</code>.</li> |
| <li><code>delay.type = ’GammaSpeedDelay’</code>: This mode closely resembles the GammaRandomDelay. Additionally, a penalty for the velocity with which |
| the node is moving is calculated. This penalty is then added to the original delay. The GammaRandomDelay and the GammaSpeedDelay are |
| derived from a measurement campaign during a research project at the DCAITI.</li> |
| </ul> |
| <p>The two different modes for the downlink are <code>unicast</code> and <code>multicast</code> which are configured separately. Multicast aims to simulate the |
| features of Multimedia Broadcast Multicast Service (MBMS). The main difference in terms of the transmission for unicast and multicast |
| is the handling of undeliverable messages. For unicast, the options <code>lossProbability</code> and <code>maxRetries</code> are used. Pr is short for |
| packet retransmit and denotes the probability for a failed delivery and a subsequent retransmit. The maximum number of retries |
| for the retransmission is configured through the <code>maxRetries</code>-option. The probability of a successful |
| retransmit is recalculated on every try.</p> |
| <p>In case of multicast the <code>lossProbability</code> is used as packet loss rate. The value is factored into the delay calculation. |
| In contrast to the unicast, just one transmission attempt is made for multicast.</p> |
| <h3 id="operation">Operation</h3> |
| <p>Beside the transmission simulation, the Addressing and Routing is the other important aspect of the Cellular Simulator. This task is enabled |
| by the Geocaster.</p> |
| <p>The Geocaster evaluates the message headers for cellular messages, which are created by the communicating applications in the |
| Application Simulator.</p> |
| <p>It supports the following addressing and casting schemes.</p> |
| <p> |
| <a href="https://www.eclipse.org/mosaic/docs/develop_applications/communication/#cellular-topocast"><strong><code>CellTopocast</code></strong></a> is the normal unicast, where the Geocaster simply resolves |
| the single receiver via theIPResolver. Hence, the CellTopocast directly routes the message further. Currently, Topocast doesn’t allow |
| broadcast or anycast addresses, but any transmission protocols (tcp, udp).</p> |
| <p> |
| <a href="https://www.eclipse.org/mosaic/docs/develop_applications/communication/#cellular-geocast"><strong><code>CellGeoUnicast</code></strong></a> addresses every node in the destination area individually. |
| In this way it takes a geographic address and results in a loop to generate multiple unicasts.</p> |
| <p> |
| <a href="https://www.eclipse.org/mosaic/docs/develop_applications/communication/#cellular-geobroadcast"><strong><code>CellGeoBroadcast</code></strong></a>, which is basically MBMS, uses one broadcast to all |
| nodes in the destined regions.The MBMS uses the different transmission mode of multicast in the downlink. CellGeoUnicast as well as |
| CellGeoBroadcast require broadcast, but don’t allow tcp (as ack for broadcasts is denied).</p> |
