Publication number: 20080123619Abstract: An apparatus, a method, and computer readable medium thereof for dividing a beacon interval are provided. The beacon interval is divided into a plurality of sub-beacon intervals in various sizes and each of the sub-beacon intervals is further divided into a predetermined number of time slots. Each of the sub-beacon intervals is similar to the beacon interval, and the difference between them is their time lengths. Therefore, more time slots in various sizes are provided. Consequently, nodes covered by the beacon interval can choose suitable time slots to transmit data to reduce waste of bandwidth. In addition, more time slots that are sub-contention free periods are provided, so transmitting data via time slots that are sub-contention access periods can be prevented. It means that collisions and data transmission can be reduced as well.Type: ApplicationFiled: April 5, 2007Publication date: May 29, 2008Applicant: INSTITUTE FOR INFORMATION INDUSTRYInventors: Li-Chun Ko, Chih Lung Chang, Hua-Wei Fang, Chih-Hung Hung

Publication number: 20080108300Abstract: A system, a method, a computer program product, and a computer readable medium thereof for a new node joining a wireless network are disclosed. The wireless network system comprises a plurality of child nodes and a plurality of father nodes corresponding to those child nodes. Each of the child nodes and each of the father nodes can send a beacon packet, which comprises an absolute time index and a relative time index. When the new node collects the absolute time indexes and relative time indexes of neighboring child nodes, it can calculate the occupied absolute time index quickly and derive its absolute time index from the unoccupied absolute time index. Based on the same reason, when applying the system to a scheduling algorithm, the scheduled result can be derived quickly. In addition, the system can prevent the accumulated error. The system can be applied to a low-rate wireless network.Type: ApplicationFiled: February 22, 2007Publication date: May 8, 2008Applicant: Institute for Information IndustryInventors: Chi-Wen Teng, Chih Lung Chang, Yung-Chih Liu
