◆ ReceivePacket()

void ns3::SensorNode::ReceivePacket ( Ptr< Socket > socket )

Executed when a new onion is received.

Repeatedly call ns3::Wsn_node::RecvSegment() until the whole packet is received. Then, check if the onion is valid by comparing the onionID of the onion and the onion sequence number in the ns3::OnionValidator::GetOnionSeq(). If the onion is not valid then delete the onion. Otherwise: Signal that the onion was received. Process the onion head and retrieve the next hop ip value. (ns3::SensorNode::ProcessOnionHead()) Processs the onion body. (ns3::SensorNode::ProcessOnionBody()) Send the onion meesage to the next hop ip.

Parameters

[in] socket the incoming connection
