Support for Parallel Drone-based Task Execution at Multiple Edge Points

Edge Node side:

Requirements:

• create a TeCoLa Docker environment.
• python 2.7

EdgeServer.py : It is a TeCoLa mission program that runs the EdgeServer entity. To start a EdgeServer a unique id should be assigned: python EdgeServer.py -z|--zone [zoneID]

Cloud Side

Requiremets:

• python 3.8.10

Entities:

• Registry.py : without this entity the system fails to start its executions: python.py Registry.py.
• FTPServer.py : runs in the background and handles the Edge Server's FTP request during the "file space synchronitation".
  • before execution the space_file/ directory should be already created. python.py FTPServer.py.
• LogServer.py : runs in the background, accepts Edge Server's messages through a TCP connection. python.py LogServer.py.
• TaskManager.py : provides the command-line interface to user. python.py LogServer.py.

User - Commands

$ list [ <zone-id>| * ]

$ reset [ <zone-id>| * ]

$ kill

$ stat

$ run <edgeTask>@[zone1<arg1,arg2,..>;..] | ... | <managerTask>@[zone1;..]<arg1,arg2..>

Demo Job In the demo_job directory, there is an example of a pipeline of tasks:

• scannerTask.py drone task for scanning a rectangle
• detectorTask.py:
  • requires the configuration files from demo_job/config. that belongs to yolo-real-time-object-detection
  • python modules (for python 2):
    • sudo pip2 install numpy==1.15.0
    • pip2 install opencv-python==4.2.0.32
    • sudo apt-get install libglib2.0-0
    • sudo apt-get install libSM.so.6
    • sudo apt-get install -y libsm6 libxext6
    • sudo apt-get install -y install -y libxrender-dev
    • sudo apt-get install -y libxrender-dev
• aggreagatorTask.py

run command (supposing you have two zones: zoneA, zoneB):

run scannerTask.py@[zoneA<'uav1',37.9278579,23.6500001>;zoneB<'uav2',37.927858,23.661409901>] | detectorTask.py@[zoneA<'tmp','.'>;zoneB<'tmp','.'>] | aggregatorTask.py@[zoneA;zoneB]<'zoneA','zoneB'>
