MULTI-HOP WIRELESS NETWORK USING OPPORTUNISTIC ROUTING SCHEME AND COMMUNICATION METHOD USING THE NETWORK

摘要

PURPOSE: A multi-hop wireless network opportunistically using a routing technique and a communicating method using the same are provided to opportunistically receive data packets by a destination node and to supply a received result to other nodes in a path transmitting the data packet. CONSTITUTION: A receiver (631) opportunistically receives a data packet transmitted among a source node or one or more intermediate nodes. A determining unit (632) determines whether or not the data packet is received by the receiver. A response message transmitter (633) transmits a destination response message to the source node or one or more intermediate nodes according to the destination in which the data packet is received.
