Member Function Documentation

void AODVForwardingPolicy::cache

(

DTN::BundlePointer &

p

)

[virtual]

Cache information about a newly stored Bundle for faster access.

By default, nothing is done. Derived classes may override this.

Parameters:

p

A reference to a Bundle in the BundleStore

Reimplemented from DTN::ForwardingPolicy.

Definition at line 65 of file AODVForwardingPolicy.cc.

bool AODVForwardingPolicy::forward

(

DTN::Bundle *

b

)

[virtual]

Attepmt to forward a Bundle.

Concrete derived classes must implement this.

Parameters:

b

A Bundle to forward

Return values:

	true	b was forwarded
	false	b was not forwarded and should be considered for local storage

Implements DTN::ForwardingPolicy.

DTN::Bundle * AODVForwardingPolicy::forwardOn

(

const DTN::Link &

l

)

[virtual]

Attepmt to forward along a Link that has become available.

Concrete derived classes must implement this.

Parameters:

l

A Link capable of transmitting a new Bundle

Returns:

a Bundle to forward

Implements DTN::ForwardingPolicy.

References DTN::Bundle::destination(), fill_addr(), DTN::BundlePointer::isNull(), DTN::NodePolicy::m_owner, DTN::BundlePointer::next(), DTN::BundlePointer::repr(), and DTN::Bundle::source().

void AODVForwardingPolicy::handleMessage

(

const DTN::Bundle &

b

)

Pass a protocol message encapsulated in a DTN::Bundle to AODV.

Parameters:

b

A bundle containing an AODV protocol message

void AODVForwardingPolicy::notify

(

)

Notify the policy that a new AODV route has been established.

This will look for a queued DTN::Bundle that can now be sent, assuming the link is available.
