Abstract: A wireless roaming method and related system are provided. The method is applicable to an access control device and includes: determining a moving direction of a mobile device that is in a first connection connecting with a first access point; establishing, by a second access point and in response to a determination that the moving direction meets a preset condition, a second connection connecting the mobile device with the second access point, and disconnecting, by the first access point, the first connection. The first access point and the second access point are both connected to the access control device, and have a same static address or a same Identity Resolving Key.

Abstract: Hierarchical multi-agent reinforcement learning may be used for joint order dispatching and fleet management for ride-sharing platforms. Information may be obtained. The information may include a status of a ride- sharing platform and a set of messages. The obtained information may be input into a trained hierarchical reinforcement learning (HRL) model. The trained HRL model may include at least one manager module corresponding to a region, and the at least one manager module may include a set of worker modules each corresponding to a division the region. At least one goal of the division in the region may be obtained based on the status of the ride- sharing platform and the set of messages. A vehicle action may be generated for each vehicle in the division in the region based on the status of the ride- sharing platform, the set of messages, and the at least one goal.

Abstract: Systems and methods for managing a compromised autonomous vehicle server are described herein. A processor may obtain an indication of a first server configured to control an autonomous vehicle being compromised. The autonomous vehicle may have previously been provisioned with a first public key. The first public key may be paired with a first private key. A processor may compile command information. The command information may include a command for the autonomous vehicle and a digital certificate of a second server configured to control the autonomous vehicle in the event of the first server being compromised. The digital certificate may include a second public key and may be signed with the first private key. The command may be signed with a second private key associated with the second server. The second private key may be paired with the second public key.

Abstract: Systems and methods for managing networked communication sessions are described herein. A processor may obtain, by a driver running in a first operating mode of the one or more processors, session information and content information from a client application to be communicated to an external entity over a network. The processor may redirect, by the driver, the session information and the content information to a local proxy running in a second operating mode of the one or more processors via a local listening port of the local proxy. The redirecting may comprise modifying the session information to generate modified session information. The processor may obtain, at the local proxy, the modified session information and the content information. The processor may establish a communication channel between the local proxy and the external entity by modifying the modified session information to communicate the content information to the external entity.
