Abstract:
A slotted message access protocol can be implemented for transmitting messages in a communication network. A beacon period may be divided into multiple communication slots. A master network device may register a first client network device and provide registration information to the first client network device. The registration information may include one or more encryption keys to allow the first client network device to securely transmit messages in the communication network. The client network device may use an encryption key associated with a second client network device to decrypt messages received from the second client network device. Furthermore, the first client network device may use a contention-based communication slot to request allocation of contention-free communication slots for subsequent transmissions. The master network device may temporarily allocate contention-free communication slots to the client network device for a specified duration.

Abstract:
A service provider device of a local communication network communicates a first frame with an electric vehicle via a first communication medium to associate with the electric vehicle, establish a communication link with the electric vehicle, and to add the electric vehicle to the local communication network. After an association process between the electric vehicle and the service provider device is successfully completed, the electric vehicle and/or the service provider device can execute operations that extend the utility of their respective communication devices by switching to a new communication medium. By switching to the new communication medium, the electric vehicle and/or the service provider device can connect to a remote communication network. The service provider device communicates a second frame with at least a network device of the remote communication network via the new communication medium.
Abstract:
A feature-capable device, i.e. a device that supports channel reuse can execute operations for determining whether to reuse or share a communication channel with a neighbor network when a local network (that comprises the feature-capable device) and/or the neighbor network comprise legacy devices that do not support adaptive channel reuse feature. The feature-capable device can determine channel performance measurements associated with each legacy device in the local network and/or in the neighbor network and can compare the channel performance measurements against corresponding performance thresholds. The local network and the neighbor network can reuse the channel if the channel performance measurements associated with all the legacy devices are in accordance with the corresponding performance thresholds. The local network and the neighbor network can share the channel if the channel performance measurements of at least one of the legacy devices is not in accordance with the corresponding performance thresholds.
