摘要： A system and method for vehicular networking and applications visualization comprises selecting a simulation area, converting the selected simulation area to graph representation, eliminating streets outside the simulation area, generating, using the graph representation, vehicles and random vehicle traffic in the simulation area, calculating vehicle movement in coordinates, transforming the calculated coordinates into a format compatible with a general purpose communication networking simulation tool, simulating, using the transformed calculated coordinates and the general purpose communication networking simulation tool, an application, and performing visualization of the simulation. The application can be local traffic information, the vehicle movement and communication among the vehicles. The simulation can be at least 2000 seconds and communication can be disruption tolerant. The visualization of the simulation can comprise a global view of all vehicles and one or more local views, each local view of one vehicle. The simulation area can be selected from a geographic map.

摘要： A plurality of servers for processing client requests forward the requests among themselves to achieve a balanced load. When a server initially receives a client request, it randomly selects another of the plurality of servers, referred to as a first-chance server, and forwards the request to this server. Upon receiving the request, the first-chance server determines if it is overloaded and if not, processes the request. However, if overloaded, the first-chance server compares its load to the load of one or more predetermined next-neighbor servers. If the next-neighbor server(s) are more loaded than the first-chance server, the first-chance server processes the request. Otherwise, the first-chance server forwards the request to the least loaded next-neighbor server. The next-neighbor receiving the request either processes it directly, or alternatively, based on its current load and that of its next-neighbor server(s), forwards the request to another next-neighbor server for processing.

摘要： The present invention presents an architecture to dynamically measure and estimate the throughput perceived by a user during a connection in real-time in a wireless network system. The architecture system design of the present invention allows for information gathering independent of the mathematical models used and takes into account security settings in the network hosts. The present invention also sets forth a number of throughput estimators (TEs) that can be used within the architecture to gather the information needed to carry out the throughput estimation calculations. The throughput estimations can then be used for download rate control, QoS, load balancing, etc. The present invention also provides algorithms to calculate the real-time throughput experienced by a user flow.

摘要： A hybrid mobile ad-hoc network and a method of operating the same, including a mobile network node and a plurality of static network nodes randomly distributed over a coverage area with a predetermined density. The static network nodes form a static infrastructure backbone of the hybrid mobile ad-hoc network. Position information of the static network nodes, either through position awareness or triangulation with reference to other static nodes enhances the network function. The method tracks mobile node position with a minimum of overhead because of the fixed infrastructure of static nodes. The infrastructure can self-heal by placing excess static nodes in a hibernating state, and activating those in response to the failure of a nearby static node.
