| 摘要 |
<p>The invention relates to a method of operating a communication network, the network comprising a plurality of stations (A to O) which are able to transmit data to and receive data from one another so that a message comprising a plurality of data packets is sent from an originating station (A) to a destination station (O) via at least one opportunistically selected intermediate station. The method makes use of probe signals transmitted from each station on a selected probing channel to which other stations respond to indicate their availability as destination or intermediate stations. A Request to Send message is sent, with a Clear to Send message returned by an available station. The station with data to send opportunistically selects an available station and the selected station uses a Packet Acknowledge message to confirm successful reception of the transmitted data packet. An End-to-End Acknowledge message is sent by the originating station (A), directly or indirectly, to confirm receipt of said data packets. <IMAGE></p> |
