Context Sharing Simulation on ONE Simulator, the results are used in the paper CHITCHAT: Navigating Tradeoffs in Device-to-Device Context Sharing

• [2015/08/19] ln -s ../experiment/ ./experiment should be executed in the ONE simulator directory.
  • Database loads the contexts assuming the base directory is in ContextSharingSimulation directory, but with one simulator this becomes one_simulator.
  • This symbolic link solves this issue.
• [2015/08/19] Contexts in experiment/contexts/SimulationSimple/contexts are loaded when the simulation starts. Refer to Database object in ContextProcessor package.

Try to change as little as possible in the one_simulator.

All the one simulator code is in one_simulator directory, all the settings should be in the one_simulator directory

The working direcgtory becomes PATH/one_simulator

core/SimScenario.java/createHosts() method: for each application, add them into listener list based on what types it implements.

protoApp = (Application)t.createIntializedObject(
        APP_PACKAGE + t.getSetting(APPTYPE_S));
// smcho added
// If the application implements connectionListner, it should be added to the lister group
if (protoApp instanceof ConnectionListener) {
    addConnectionListener((ConnectionListener) protoApp);
}
if (protoApp instanceof MessageListener) {
    addMessageListener((MessageListener) protoApp);
}
if (protoApp instanceof MovementListener) {
    addMovementListener((MovementListener) protoApp);
}
if (protoApp instanceof UpdateListener) {
    addUpdateListener((UpdateListener) protoApp);
}
if (protoApp instanceof ApplicationListener) {
    addApplicationListener((ApplicationListener) protoApp);
}
// smcho added end

This is an example of message.

0-Set(is0, is3(3->0[52]), is2(2->0[48]))
1-Set(is1, is3(3->1[52]))
2-Set(is2, is0(0->2[39]), is4(4->2[58]))
3-Set(is3, is0(0->3[39]), is1(1->3[28]))
4-Set(is4, is2(2->4[48]))

The format is is\d+(\d+->\d+[\d+])?.

• is\d+ shows the originator of the context.
• \d+->\d+ shows the sender and receiver of the context.
• [\d+] shows the size of context.

We may be able to add more information (i.e., the type of context) to be further analyzed.
