Constructor Summary

TOSMoteAccess()
Creates a new TOSMoteAccess object, and tries to initialize MoteIF from TinyOS in order to access the sensor network.

Constructor Detail

TOSMoteAccess

public TOSMoteAccess()

Creates a new TOSMoteAccess object, and tries to initialize MoteIF from TinyOS in order to access the sensor network.

Method Detail

doRead

public void doRead(RequestID rid,
                   MoteRequest mr_in,
                   IMoteListener ml)

Description copied from interface: IMoteAccess

Method by which the MoteAccess layer is requested to start an unconditional read operation.

Specified by:

doRead in interface IMoteAccess

Parameters:

rid - : the RequestID that the client application has generated.

mr_in - : the MoteRequest object describing the desired reading.

ml - : reference to the IMoteListener implementation to be notified of incoming results.

stopOperation

public void stopOperation(RequestID rid)

Description copied from interface: IMoteAccess

Method used to stop a running operation, i.e. a reading or a reaction.

Specified by:

stopOperation in interface IMoteAccess

Parameters:

rid - : the RequestID identifying the operation to be stopped.

injectReaction

public void injectReaction(RequestID rid,
                           MoteReaction mr_in,
                           IMoteListener ml)

Description copied from interface: IMoteAccess

Method by which the MoteAccess layer is requested to install a reaction.

Specified by:

injectReaction in interface IMoteAccess

Parameters:

rid - : the RequestID that the client application has generated.

mr_in - : the MoteReaction object describing the desired reaction.

ml - : reference to the IMoteListener implementation to be notified of incoming results.

setParameter

public boolean setParameter(java.lang.String parameter,
                            int value)

Description copied from interface: IMoteAccess

Method by which parameters at the MoteAccess level can be set.

Specified by:

setParameter in interface IMoteAccess

Parameters:

parameter - String identifying the parameter to be modified

value - integer to which the parameter has to be set.

Returns:

boolean indicating wheter the update has taken place or not

getParameter

public int getParameter(java.lang.String parameter)

shutdown

public void shutdown()

This method shuts down the TOSMoteAccess, more specifically it lets the message sending Thread know that it's time to die. It is quite useless though, since the underlying MoteIF framework seems to have no way of exiting but a brutal System.exit()... :-(

messageReceived

public void messageReceived(int dest_addr,
                            Message msg)

stopRequest

private void stopRequest(RequestID rid,
                         java.lang.String reason)

stopConfigRequest

private void stopConfigRequest(ConfigRequestTOSMessage msg)

run

public void run()

This is the body of the thread that both sends messages to the sensor network and updates the timeouts.

Specified by:

run in interface java.lang.Runnable
