Abstract: A method for supporting a reliable data transmission for a wireless sensor network is provided to reliably transmit data suitably in consideration of a situation in which there are many senders or many receivers. An end-to-end packet sequence number between a sender and a receiver is used in a data packet, and a packet is transmitted by using an inter-hop packet sequence number assigned between two arbitrary nodes. When a data packet is lost between two arbitrary nodes, a node, which will receive the packet, transmits a 'NACK' message to the other node which has transmitted the packet. In case of N:1 communication that there is several senders and only one receiver, a unicast mode is operated, and the inter-hop packet sequence number assigned between two arbitrary nodes is used by an node that transfers a packet and a node that receives the packet.
