Elijah: Cloudlet Infrastructure for Mobile Computing

A cloudlet is a new architectural element that arises from the convergence of mobile computing and cloud computing. It represents the middle tier of a 3-tier hierarchy: mobile device - cloudlet - cloud. A cloudlet can be viewed as a "data center in a box" whose goal is to "bring the cloud closer".

Tested platform

Ubuntu 12.04 LTS 64 bit


This project is composed of two parts: Cloudlet and Cloud. The role of the Cloud part is periodically receiving heartbeats from cloudlets and return IP address of nearby cloudlets using the IP address of the querying client.

  • For Cloudlet

    You will need:

    • libvirt python binding
    • avahi-daemon avahi-python
    • python packages listed at requirements.txt

    To install, you need

      > $ sudo apt-get install python-pip python-libvirt avahi-daemon python-avahi
      > $ sudo pip install -r requirements.txt

    For some distribution, Avahi-daemon doesn't start at boot. You can enable it

      > $ sudo service avahi-daemon start
      > $ sudo update-rc.d avahi-daemon defaults
  • For Cloud

    See ./server/register-rest/

You can’t perform that action at this time.
