摘要： A method assigns backhaul links in a cooperative wireless network including a control unit (CU) connected to a set of access points (APs) by a set of backhaul links, and wherein the APs are connected to an end user by wireless channels. A reliability of each backhaul link is determined to produce a set of reliabilities. A distance between each AP and the end user is determined to produce a set of distances. Using the set of reliabilities and the set of distances, probabilities of successful reception of a message transmitted from the CU to the end user via the backhaul links and the wireless channels are determined. Then, the backhaul links are assigned according to the probabilities of successful reception of the message by the end user.

摘要： Packets are transmitted by a server to mobile nodes in a coverage area of a wireless network using a coverage and reliability map, which indicates qualities and reliabilities of links between the server and the nodes. When a new packet is received in the server, the server transmits the packet if a current load of the packets including the new packet is less than a peak load constraint. Otherwise, the new packet is delayed for one time slot. Packets are transmitted according to associated priorities.

摘要： A scanner for image reconstruction of a structure of a target object uses a neural network trained to classify each segment of a sequence of segments of a modified wave into one or multiple classes. The sequence of segments corresponds to the sequence of layers of the target object, such that a segment of modified wave corresponds to a layer having the same index in the sequence of layers as an index of the segment in the sequence of segments. The scanner executes the neural network for each wave modified by penetration through the layers of the target object to produce the classes of segments of the modified waves. Next, the scanner selects the classes of segments of different modified waves corresponding to the same layer to produce an image of the layer of the target object with pixel values being functions of labels of the selected classes.
