摘要： A communication apparatus originally transmits data packets via a first channel based on a first beacon interval. A memory thereof records the first beacon interval. A receiving interface thereof receives information of a second channel. A processor thereof determines whether the second channel has been used according to the information. If not, a transmission interface thereof switches the communication channel to the second channel, and transmits data based on the first beacon interval via the second channel in order to solve the problem that packets are delay for transmission or even abandoned due to overload of the beacon network

摘要： 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.

摘要： A data processing method for communication for a network having a plurality of nodes and a data collection device is provided. First, one of the nodes is selected according to a schedule for overhearing a reference data transmitted by a reference node to the data collection device. Then, a predicted data is calculated by the selected node according to the reference data and a corresponding prediction module. Next, the predicted data is compared with an actual data captured by the selected node, and an error between the predicted data and the actual data is transmitted to the data collection device. The selected node needs not to transmit any data to the data collection device if there is no error between the predicted data and the actual data. Thereby, the quantity of data to be transmitted is greatly reduced, and accordingly problems caused by insufficient bandwidth of the network are avoided.
