Crowd crisis movement for the ONE simulator

A fork of the Opportunistic Network Environment simulator (the ONE) featuring crisis crowd movement.

Generated Javadoc can be found at : https://davidsan.github.io/one or can be generated using doc/create_docs.sh script.

Implementations

Crowd movement

Crowd movement is implemented with the DangerMovement class and his sub-models (EvacuationCenterMovement, HomeMovement, RandomPathMapBasedMovement, ShortestPathMapBasedPoiMovement, SosMovement).

Closed roads

Closed roads are implemented using AccidentGenerator which generate AccidentEvent. Those events make changes to the MapNode's instances by calling the close() method.

Changes

This fork is based on version 1.5.1 RC2 of the ONE simulator.

Core

• core.DTNHost : added known positions, known accidents, warned and stucked states...
• core.NetworkInterface : disable interface when node is at evacuation center
• core.SimScenario : store the time at which the number of nodes to save has been reached

Movement

• movement.DangerMovement : danger movement model
• movement.EvacuationCenterMovement : movement model for nodes at evacuation centers
• movement.HomeMovement : movement model for nodes at home
• movement.RandomPathMapBasedMovement : movement model for node walking randomly
• movement.ShortestPathMapBasedPoiMovement : movement model for node walking to an evacuation center
• movement.SosMovement : movement model for stranded nodes
• movement.map.PointsOfInterestEvac : POI for evacuation centers
• movement.map.DijkstraPathFinder : Dijkstra path finder with accidents discovery
• movement.map.DijkstraPathFinderOptimal : same as DijkstraPathFinder but only compute when necessary
• movement.HotspotMovement : movement model for hotspot nodes

Routing and applications

• routing.DirectDelivery2 : direct delivery router with explicit removal of delivered messsages
• applications.DangerApplication : send alert message with known locations of other hosts and known accidents, and process received messages
• applications.HotspotApplication : application for hotspot, only process received messages created from DangerApplication

Events

• input.EmptyEvent : an empty event doing nothing
• input.AccidentEvent : an event for closing randomly selected junctions
• input.AccidentGenerator : generator of accidents

GUI

• movement.map.MapNode : added new property for closed map node
• movement.map.SimMap : added evacuation centers' locations
• gui.playfield.NodeGraphic : for coloring the node according to the movement model
• gui.playfield.MapGraphic : for coloring the road closed
• gui.GUIControls : raised default speed in GUI mode

Database and reports

• db.Database : handling database connections
• db.Queries : reader for queries properties file
• db/queries.properties : properties files for SQL request
• report.ReportDB : generic class for report into SQL database
• report.MovementReportDB : movement report into database
• report.LocationReportDB : location report into database
• report.TimeReportDB : various time report into database
• report.ReportCSV : generic class for report into CSV file
• report.LocationReportCSV : location report into CSV file

Others

• tools/computeWorldSize.sh : compute MovementModel.worldSize given a WKT map file
• tools/pretty_print_db.sh : shortcut to display a SQLite database
• test.AllWorkingTests : JUnit tests for passing tests as of v1.5.1 RC2 of the ONE simulator
• .travis.yml : Travis-CI file
• build.xml : Ant file

Scripts for cluster using OAR batch scheduler

• bench/build-project.sh : compile the project in a cluster's node
• bench/csv2db.sh : convert CSV file into SQLite database
• bench/launch-jobs.sh : submit multiple ONE simulation jobs to the OAR batch scheduler
• bench/process-csv.sh : convert multiple CSV files into SQLite databases using cluster's nodes
• bench/task.sh : single job submitted by launch-jobs.sh

Maps

• santiago.wkt : surface : unknown, population : unknown
• HelsinkiMedium/roads.wkt : surface : 60 km^2, population : 124K, population 16-74 years old using a smartphone : 60K
• usantiago.wkt : surface : 2,5 km^2, population : 26K
• usantiago2.wkt : surface : 2,5 km^2, population : 26K (cropped roads)
• usach.wkt : surface : 0.8 km^2, population : 6K
• santiago_center.wkt : surface : 30 km^2, population 437K

Associated POI files can be found with the map name suffixed with _pois (eg. santiago_center_pois.wkt)

usantiago2 (1 POI) and santiago_center (3 POI) have their POIs located at various hospitals' location.

Example of scenario

An example of scenario can be found in the danger_settings.txt file.
