摘要： An embedded system includes a first wireless node and a number of second wireless nodes, each of which includes a wireless transceiver, a memory storing a schedule defining transmission and reception of test packets, and a processor transmitting and receiving the test packets responsive to the schedule. The memories store a corresponding predetermined application employing some of the wireless communications, and a corresponding predetermined measurement function measuring wireless communication performance. A corresponding one of the schedules is executed by the corresponding predetermined measurement function. The second wireless nodes wait to receive a number of the test packets before being synchronized with their schedule and receiving and transmitting the test packets according to their schedule. The processors store data from the test packets to assess wireless communication performance between corresponding nodes.

摘要： A wireless communication network includes a network coordinator (NC) having plural channels and plural wireless transceivers, and plural nodes. Each node has status information, a number of channels and a number of wireless transceivers. Each node and the NC communicate in a Carrier Sense Multiple Access mode. Each node communicates the status information thereof to or toward the NC in a Time Division Multiple Access mode having plural time slots. The NC assigns the time slots and the channels to the nodes to provide a plurality of collision-free schedules therefor. The NC sends, for each node, a corresponding one of the collision-free schedules to or toward a corresponding one of the nodes. Each collision-free schedule includes a corresponding number of the time slots and a corresponding number of the channels that the corresponding one of the nodes employs to communicate the status information thereof to or toward the NC.
