Abstract: Systems and methods are provided for modeling and simulating a communication network operating under at least one communication protocol, which supports a Smart Grid electricity network. Communication performance data of the communication network are generated by a processor based on operating behavior of the Smart Grid with a plurality of assets under a first condition. Devices in the Smart grid are grouped in bins for rapid modeling. One or more different configurations of the communication network are entered into the processor and related performance data is also generated. Network configurations are compared based on the generated performance data which may include end-to-end delay and reception rate. Processor based systems to perform modeling methods are also provided.

Abstract: A computer implemented technique includes receiving, at a server, a request to utilize an intermediary device to establish a wireless hotspot for a mobile computing device to access a private computing network via a network device. The technique includes receiving, at the server, access information from a first user having control of the private computing network and the network device, the access information specifying users and their corresponding levels of access to the private computing network via the wireless hotspot. The technique includes receiving, at the server, identification information for a second user associated with the mobile computing device. The technique also includes transmitting, from the server and to the intermediary device, a level of access to the private computing network via the wireless hotspot causing the intermediary device to grant the mobile computing device the level of access to the private computing network via the network device.

Abstract: In a framework for acquiring and analyzing data from a network of sensors, plug-in software interfaces are used to provide scalability and flexibility. Data collection set-up data is exchanged through one or more first plug-in software interfaces with data collection devices, to configure the processor to collect measurement data from the data collection devices. Analysis set-up data is exchanged through one or more second plug-in software interfaces with one or more data analysis software packages, to configure the processor to provide a predefined subset of the measurement data to the data analysis software packages and to accept analysis results from the data analysis software packages. Measurement data and analysis results are subsequently exchanged through the plug-in interfaces.

Abstract: Methods, systems, and devices for monitoring roadway traffic. A method includes transmitting wireless signals from a plurality of roadside equipment (RSE) devices, including from a first RSE device and from a second RSE device that are located at separated positions of an intersection. The method includes receiving responses by the first RSE device and second RSE device from a wireless device. The responses include a unique identifier corresponding to the wireless device.
