Patent number: 7969951Abstract: A power-saving wireless network, a packet transmitting method for use in the wireless network, and computer readable medium therefor are provided. The wireless network comprises a PAN coordinator, a receiving node and a transferring node. When the transmitting node has a packet planed to be transmitted to the receiving node which is in a sleep mode, the packet is alternatively transmitted to the PAN coordinator. As soon as the receiving node wakes from the sleep mode, all packets are transmitted to the receiving node from the PAN coordinator. After the packets are all successfully transmitted, the receiving node turns back to the sleep mode subsequently. Thereby, the performance of the wireless network would not be restricted to the sleep period and memory capacity. Thus, the nodes in the wireless network would greatly facilitate saving power.Type: GrantFiled: June 30, 2006Date of Patent: June 28, 2011Assignee: Institute for Information IndustryInventors: Yung-Chih Liu, Shih-Hung Liu, Ming-Jer Tsai
