Release notes

1- Cloud server processing was simplified in the initial version, it is handled via cloudsim components now.

2- Cloud server manager, edge server manager, mobile device manager and vm allocation policy are used as abstract class in factory pattern to allow developers to use different business logic without modifying EdgeCloudSim source code.

3- The task and place types are no longer defined as enumeration. They are used as integer value in order to manipulate more place type without modifying enum variable.

4- Two sample applications (one of them is simple and the other one extended application) are added along with the corresponding matlab files to plot statistics.

5- Cloud server properties are added to the simulation settings file

6- New log items are added to simulation result files

7- Code refactoring is applied including the modification of comments

# EdgeCloudSim
EdgeCloudSim provides a simulation environment specific to Edge Computing scenarios where it is possible to conduct experiments that considers both computational and networking resources. EdgeCloudSim is based on CloudSim but adds considerable functionality so that it can be efficiently used for Edge Computing scenarios. EdgeCloudSim is an open source tool and any contributions are welcome. If you want to contribute EdgeCloudSim please check below feature list and the [contributing guidelines](/CONTRIBUTING.md). If you want to use EdgeCloudSim in your research work, please cite our paper [[1]](http://ieeexplore.ieee.org/document/7946405/).
## Needed Features
* Mist computing features (executing tasks on mobile device)
* Incorporating cellular access network model into EdgeCloudSim (3G/4G/5G)
* Task migration among the Edge or Cloud VMs
* Energy consumption model for the mobile and edge devices as well as the cloud datacenters
* Adding probabilistic network failure model by considering the congestion or other parameters such as the distance between mobile device and the WiFi access point.
* Visual tool for displaying the network topology
# EdgeCloudSim: An Environment for Performance Evaluation of Edge Computing Systems
EdgeCloudSim provides a modular architecture to provide support for a variety of crucial functionalities such as network modeling specific to WLAN and WAN, device mobility model, realistic and tunable load generator. As depicted in Figure 2, in the current EdgeCloudSim version there are five main modules available, namely: Core Simulation, Networking, Load Generator, Mobility and Edge Orchestrator. To ease fast prototyping efforts, each module contains a default implementation that can be extended easily.
<p align="center">
<img src="/doc/images/edgecloudsim_diagram.png" width="55%">
<p align="center">
Figure 1: Relationship between EdgeCloudSim modules.
</p>
</p>
## Mobility Module
The mobility module manages the location of edge devices and clients. Since CloudSim focuses on the conventional cloud computing principles, the mobility is not considered in the framework. In our design, each mobile device has x and y coordinates which are updated according to the dynamically managed hash table. By default, we provide a nomadic mobility model but different mobility models can be implemented by extending abstract MobilityModel class.
<p align="center">
<img src="/doc/images/mobility_module.png" width="55%">
</p>
## Load Generator Module
The load generator module is responsible for generating tasks for the given configuration. By default, the tasks are generated according to a Poisson distribution via active/idle task generation pattern. If other task generation pattern is required, abstract LoadGeneratorModel class should be extended.
<p align="center">
<img src="/doc/images/task_generator_module.png" width="50%">
</p>
## Networking Module
The networking module particularly handles the transmission delay in the WLAN and WAN by considering both upload and download data. The default implementation of the networking module is based on a single server queue model. Users o EdgeCloudSim can incorporate their own network behavior models by extending abstract NetworkModel class.
<p align="center">
<img src="/doc/images/network_module.png" width="55%">
</p>
## Edge Orchestrator Module
The edge orchestrator module is the decision maker of the system. It uses the information collected from the other modules to decide how and where to handle incoming client requests. In the first version, we simply use a probabilistic approach to decide where to handle incoming tasks but more realistic edge orchestrator can be added by extending abstract EdgeOrchestrator class.
<p align="center">
<img src="/doc/images/edge_orchestrator_module.png" width="65%">
</p>
## Core Simulation Module
The core simulation module is responsible for loading and running the Edge Computing scenarios from the configuration files. In addition, it offers a logging mechanism to save the simulation results into the files. The results are saved in comma-separated value (CSV) data format by default, but it can be changed to any format.
## Extensibility
EdgeCloudSim uses a factory pattern making easier to integrate new models mentioned above. As shown in Figure 2, EdgeCloudsim requires a scenario factory class which knows the creation logic of the abstract modules. If you want to use different mobility, load generator, networking and edge orchestrator module, you can use your own scenario factory which provides the concrete implementation of your custom modules.
<p align="center">
<img src="/doc/images/class_diagram.png" width="100%">
<p align="center">
Figure 2: Class Diagram of Important Modules
</p>
</p>
## Ease of Use
At the beginning of our study, we observed that too many parameters are used in the simulations and managing these parameters programmatically is very difficult.
As a solution, we propose to use configuration files to manage the parameters.
EdgeCloudSim reads parameters dynamically from the following files:
- **config.properties:** Simulation settings are managed in configuration file
- **applications.xml:** Application properties are stored in xml file
- **edge_devices.xml:** Edge devices (datacenters, hosts, VMs etc.) are defined in xml file
<p align="center">
<img src="/doc/images/ease_of_use.png" width="60%">
</p>
## Compilation and Running
To compile sample application, *compile.sh* script which is located in *scripts/sample_application* folder can be used. You can rewrite similar script for your own application by modifying the arguments of javac command in way to declare the java file which includes your main method. Please note that, this script can run on Linux based systems, including Mac OS. You can also use your favorite IDE (eclipse, netbeans etc.) to compile your project.
In order to run multiple sample_application scenarios in parallel, you can use *run_scenarios.sh* script which is located in *scripts/sample_application* folder. To run your own application, you need to modify java command in *runner.sh* script in a way to declare the java class which includes your main method. The details of using this script is explained in [this](/wiki/How-to-run-EdgeCloudSim-application-in-parallel) wiki page.
You can also monitor each process via the output files located under *scripts/sample_application/output/date* folder. For example:
```
./run_scenarios.sh 8 10
tail -f output/date/ite_1.log
```
## Analyzing the Results
At the end of each iteration, simulation results will be compressed in the *output/date/ite_n.tgz* files. When you extract these tgz files, you would see lots of log file in csv format. You can find matlab files which can plot graphics by using these files under *scripts/sample_application/matlab* folder. You can also write other scripts (e.g. python scripts) with the same manner of matlab plotter files.
## Example Output of EdgeCloudSim
You can plot lots of graphics by using the result of EdgeCloudSim. Some examples are given below:

* Title: EdgeCloudSim - Mobile Device Manager
*
* Description:
* Mobile Device Manager is one of the most important component
* in EdgeCloudSim. It is responsible for creating the tasks,
* submitting them to the related VM with respect to the
* Edge Orchestrator decision, and takes proper actions when
* the execution of the tasks are finished. It also feeds the
* SimLogger with the relevant results.
* SampleMobileDeviceManager sends tasks to the edge servers or
* cloud servers. The mobile devices use WAN if the tasks are
* offloaded to the edge servers. On the other hand, they use WLAN
* if the target server is an edge server. Finally, the mobile
* devices use MAN if they must be served by a remote edge server
* due to the congestion at their own location. In this case,
* they access the edge server via two hops where the packets
* must go through WLAN and MAN.
*
* If you want to use different topology, you should modify
* the flow implemented in this class.
