METHOD OF MESSAGE DELIVERY IN DELAY TOLERANT NETWORK BY USING CONTEXT-AWARE OPPORTUNISTIC ROUTING PROTOCOL RECORDING MEDIUM AND APPARATUS FOR PERFORMING THE METHOD

摘要

Disclosed is a method for delivering a message, in a method for delivering a message in a delay tolerant network to route a message stored in each node by a contact between the nodes. The method for delivering a message includes the steps of: exchanging a message list that is information about its own message if a first node is in contact with a second node; obtaining node type information of each node based on a message storage capacity and a movement route of the first node and the second node; extracting the message stored in only the first node by comparing the message lists of the first and second nodes; and determining a message delivery condition for transmitting the extracted message to the second node, based on the node type information. Accordingly, the present invention can differently determine a message transmission condition according to the node type information.
