Abstract: This application provides a covert transmission method against active and passive cooperative attacks in a cognitive radio network. This method uses a joint design of noise uncertainty and power uncertainty to combat powerful collusion eavesdroppers. Then, the error detection probability of collusion eavesdroppers in the network and the covert transmission performance of legitimate users are analyzed. Finally, the numerical results show that the proposed scheme can guarantee the covert performance of the system, and can also resist the active and passive cooperative attacks of the collusive eavesdropper.

Abstract: This document describes trajectory planning in a three-dimensional (3D) search space with a space-time artificial potential field. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a parking trajectory algorithm to determine a trajectory by searching in a space-time artificial potential field. The trajectory includes a series of 3D waypoints, including two-dimensional (2D) positional coordinates and time coordinates, to navigate from the initial pose towards the goal pose. Operation of the host vehicle is then controlled to maneuver along the trajectory using an assisted-driving or autonomous-driving system. In this way, path searching is performed in the entire 3D search space rather than iterating between two 2D search planes. This allows motion planning for autonomous parking, especially with static and dynamic objects present, to determine an optimal trajectory in a single iteration.

Abstract: This disclosure introduces a system architecture/methodology designed to enhance network communication between online applications (e.g., Massive Multiplayer Online (MMO) games) and their users. The disclosed example implementations provide the ability to expand network entry points for online applications beyond their primary hosting service providers. The proposed architecture effectively decouples application hosting from network entry. Such separation enables online applications to leverage the network advantages of various network and computing service providers, irrespective of the hosting environment, thereby improving communication between users and the deployed applications. It further allows application developers to select hosting service providers based on optimal cost, services, and other criteria, without being constrained by network performance considerations.
