Abstract:
1. A packet transmitting method for use in a wireless network, the wireless network following the IEEE 802.15.4 standard and comprising a coordinator, an access node, a receiving node and a transferring node, the transferring node having a packet required to be transmitted to the receiving node, the method comprising: (a) determining by the transferring node that the receiving node is in a sleep mode; (b) transmitting the packet to the coordinator at a network layer of the IEEE 802.15.4 standard by the transferring node; (c) storing a pending flag in the transferring node, wherein the pending flag records the packet waiting to be received by the receiving node; and (d) temporarily storing the packet by the coordinator when the coordinator receives the packet having a pending bit as “1”; wherein when the access node receives the packet having the pending bit as “1”, the access node forwards the packet to the coordinator without amending a source address and an objective address recorded in the packet.
