The social attribute and adaptive transmission control protocol based satellite delay tolerant network routing method belongs to the technical field of satellite communication and delay tolerant network. First, the social attribute value SA of each satellite node is calculated and normalized according to the historical connection frequency of the satellite node and the ground sending station and receiving station. Then, the network message is divided into two priority categories, control message and data message, with the message size threshold theta as the boundary, and differentiated initial copy numbers are allocated respectively. The propagation path of the message copy in the network is guided through the double-track forwarding decision mechanism. Through the transmission priority function and the discard priority function, the double-priority cache management is realized, ensuring that the control message occupies the transmission channel preferentially and is protected under cache pressure. In the relay stage, the opposite end cache occupancy rate is detected, and when the occupancy rate exceeds the threshold, the relay forwarding of the data message is inhibited, and the overdue message is actively cleaned up, realizing the differentiated transmission guarantee of different business types of messages.

The present disclosure provides a method and system for energy- aware random access scheduling and resource allocation in wireless networks comprising ambient Internet of Things (IoT) devices. A paging signal is broadcast by a network entity, defining a time-frequency contention grid used by ultra-low power, battery-less devices to transmit random access messages via a slotted ALOHA protocol.

Techniques and apparatuses are described for piggybacking multiple receivers on a cryptographic value. In example aspects, an agent generates a reusable key based on a cryptographic value that is also known by the owner.
