Massive data transmission method using adaptive transmission profile in wireless sensor network for battlefield surveillance

摘要

A method of transmitting massive data in a wireless sensor network for battlefield surveillance comprises sending, by a transmission node, a burst transmission request to a reception node. The reception node selects a transmission profile to be used by the transmission node, the transmission profile comprising a physical layer packet transmission unit (PDU) size and forward error correction code (FEC). The selection depends on the signal strength (RSSI) of the burst transmission request. The reception node sends a channel resource reservation request to adjacent nodes which causes the adjacent nodes to enter a sleep state for the duration of the burst. The transmission node divides data into multiple fragmentation packets according to the transmission profile and transmits a burst of consecutive packets without acknowledgement messages from the reception node. The transmission and reception nodes switch from power management according to a duty cycle in a power saving operation mode to a burst transmission mode in order to transmit and receive the burst.
