Constructor Detail

PowerTrust_Network

public PowerTrust_Network(int numSensors,
                          double probClients,
                          double rangeFactor,
                          java.util.Collection<java.lang.Double> probServices,
                          java.util.Collection<java.lang.Double> probGoodness,
                          java.util.Collection<Service> services)

This constructor creates a new random PowerTrust Network using the given parameters

Parameters:

numSensors - Number of sensors composing the network

probClients - Probability of a sensor to act as a client requesting services

rangeFactor - Maximum wireless range of every sensor. It determines the neighborhood of every sensor

probServices - A collection of probabilities of offering a certain service, one per service

probGoodness - A collection of goodnesses about offering a certain service, one per service

services - All the services offered by the generated Network

PowerTrust_Network

public PowerTrust_Network(java.lang.String xmlFilePath)
                   throws java.lang.Exception

This method loads a network from a XML file and creates the specific corresponding PowerTrust Network

Parameters:

xmlFilePath - Path of the XML to load the network from

Throws:

java.lang.Exception - If the XML file given does not have the appropriate structure, or if a sensor links to an undefined sensor, or if a sensor links to itself

Method Detail

reset

public void reset()

Description copied from class: Network

This method resets this network to its initial state

Overrides:

reset in class Network

oscillate

public void oscillate(Service service)

Description copied from class: Network

This method turns every benevolent server in the network into malicious and counts the number of swapped servers. Then (when every server is malicious) it randomly selects malicious servers and converts them into benevolent until the number of benevolent servers is equal to the one before calling this method

Overrides:

oscillate in class Network

Parameters:

service - Service over what the oscillation is to be carried out

newSensor

public Sensor newSensor()

Description copied from class: Network

This method creates a new sensor. It must be redefined in each subclass according to the requirements of each particular trust and reputation model

Specified by:

newSensor in class Network

Returns:

New created sensor

newSensor

public Sensor newSensor(int id,
                        double x,
                        double y)

Description copied from class: Network

This method creates a new sensor. It must be redefined in each subclass according to the requirements of each particular trust and reputation model

Specified by:

newSensor in class Network

Parameters:

id - Sensor's identifier

x - X coordinate of the new sensor

y - Y coordinate of the new sensor

Returns:

New created sensor

get_sensorsTransmittedDistance

public long get_sensorsTransmittedDistance(ISearchCondition searchCondition,
                                           Service requiredService)

Description copied from class: Network

Average transmitted distance per sensor of this network

Overrides:

get_sensorsTransmittedDistance in class Network

Parameters:

searchCondition - Condition to be accomplished by the querying sensors

requiredService - Service requested by the clients

Returns:

Average transmitted distance per sensor of this network
