Member Function Documentation

void vanetsim.scenario.RSU.cleanup ( int timePerStep )

inline

Cleanup all outdated messages

Parameters

timePerStep the actual time per step

int vanetsim.scenario.RSU.getBeaconCountdown ( )

inline

Gets the current beacon countdown

Returns: the beacon countdown

int vanetsim.scenario.RSU.getCommunicationCountdown ( )

inline

Gets the current communication countdown

Returns: the communication countdown

Region vanetsim.scenario.RSU.getRegion ( )

inline

Returns the region the RSU is placed in

Returns: the region

long vanetsim.scenario.RSU.getRSUID ( )

inline

   Resets this rsu so that it can be reused.

public void reset(){

reset countdowns and other variables communicationCountdown_ = 0; knownVehiclesTimeoutCountdown_ = 0; beaconCountdown_ = (int)Math.round(x_)beaconInterval_; communicationCountdown_ = (int)Math.round(x_)communicationInterval_;

reset communication info knownVehiclesList_.clear(); knownMessages_.clear(); } /*

/** Returns the Road-Side-Unit id

Returns: the RSU id

int vanetsim.scenario.RSU.getWifiRadius ( )

inline

Returns the wifi radius

Returns: the wifi radius in cm

int vanetsim.scenario.RSU.getX ( )

inline

Returns the x coordinate of the RSU

Returns: the x coordinate

int vanetsim.scenario.RSU.getY ( )

inline

Returns the y coordinate of the RSU

Returns: the y coordinate

final void vanetsim.scenario.RSU.receiveMessage	(	int	sourceX,
		int	sourceY,
		Message	message
	)

inline

Receive a message from a vehicle.

Parameters

sourceX	the x coordinate of the other vehicle
sourceY	the y coordinate of the other vehicle
message	the message

void vanetsim.scenario.RSU.sendBeacons ( )

inline

Find vehicles in neighborhood and send beacons to them. Please check the following conditions before calling this function:

communication is generally enabled
beacons are generally enabled
if the beacon countdown is 0 or less

void vanetsim.scenario.RSU.sendEncryptedBeacons ( )

inline

Find vehicles in neighborhood and send beacons to them. Please check the following conditions before calling this function:

communication is generally enabled
beacons are generally enabled
if the beacon countdown is 0 or less

void vanetsim.scenario.RSU.sendMessages ( )

inline

send messages to all vehicles in reach. Uses broadcast, because vehicles cannot send beacons to the RSUs(often to far away)

static void vanetsim.scenario.RSU.setBeaconInterval ( int beaconInterval )

inlinestatic

Sets a new value for the beacon interval. Common to all Road-Side-Units.

Parameters

beaconInterval the new value

static void vanetsim.scenario.RSU.setBeaconMonitorZoneEnabled ( boolean beaconMonitorEnabled )

inlinestatic

Sets if beacon zones should be monitored or not. Common to all RSUs.

Parameters

beaconMonitorEnabled true to enable monitoring mix zones, else false

static void vanetsim.scenario.RSU.setBeaconsEnabled ( boolean state )

inlinestatic

Sets if beacons are enabled or not. Common to all Road-Side-Units.

Parameters

state true to enable beacons, else false

static void vanetsim.scenario.RSU.setCommunicationEnabled ( boolean state )

inlinestatic

Sets if communication is enabled or not. Common to all Road-Side-Units.

Parameters

state true to enable communication, else false

static void vanetsim.scenario.RSU.setCommunicationInterval ( int communicationInterval )

inlinestatic

Sets a new value for the communication interval. Common to all Road-Side-Units.

Parameters

communicationInterval the new value

static void vanetsim.scenario.RSU.setMonitoredMixZoneVariables	(	int	beaconMonitorMinX,
		int	beaconMonitorMaxX,
		int	beaconMonitorMinY,
		int	beaconMonitorMaxY
	)

inlinestatic

Sets the values for the monitored beacon zone. A rectangular bounding box within the specified coordinates is monitored if setBeaconMonitorZoneEnabled(boolean) is set to true.

Parameters

beaconMonitorMinX	the minimum x coordinate
beaconMonitorMaxX	the maximum x coordinate
beaconMonitorMinY	the minimum y coordinate
beaconMonitorMaxY	the maximum y coordinate

void vanetsim.scenario.RSU.setRegion ( Region region )

inline

Sets the region the RSU is placed

Parameters

region the region

static void vanetsim.scenario.RSU.setRegions ( Region regions[][] )

inlinestatic

Sets the reference to all regions. Call this on map reload!

Parameters

regions the array with all regions

Member Data Documentation

boolean vanetsim.scenario.RSU.colorCleared = false

static

flag to clear vehicle color

ArrayDeque<Vehicle> vanetsim.scenario.RSU.coloredVehicles = new ArrayDeque<Vehicle>()

static

saves all colored vehicles
