摘要： Systems and methods for routing packets by nodes in an ad hoc network in accordance with a link quality source routing protocol are disclosed. Route discovery, route maintenance, and metric maintenance are designed to propagate and keep current link quality measurements. Metric maintenance includes a reactive approach for links that a node is currently using to route packets, and a proactive mechanism for all links. Nodes are configured to include a send buffer, a maintenance buffer, a request table, link quality metric modules, and preferably a neighbor cache and a link cache. The invention allows for asymmetric links in the network. The invention may be implemented within a virtual protocol interlayer between the link and network layers. The invention may employ any particular link quality metrics, including metrics based on probing techniques as well as metrics based on knowledge gained in other ways.

摘要： A method to determine if a rogue device is connected to a specific wired network from dynamic host control protocol (DHCP) requests on the wired network. These DHCP requests are analyzed to determine the type of device issuing the request. Once the type of device has been determined, it can be checked against a list of authorized device types. If the device issuing the DHCP request is not an authorized device type, then it can be determined that the suspect device is a rogue that is connected to the specific wired network. Additionally, even if the system of the present invention determines that it is an authorized device type, if the device is not one of the few authorized devices of this type, e.g. because its MAC address is not recognized as that of one of the authorized devices, the system can flag the suspect as a rogue.

摘要： A framework for wireless network management applications in an enterprise environment using existing general purpose computing devices is presented. At least one of the devices is configured with a wireless adapter and is used as an AirMonitor to monitor one or more wireless networks. Other devices are configured as LandMonitors to monitor traffic on a wired network in the enterprise environment. At least one inference engine uses the LandMonitors and AirMonitors by assigning them monitoring tasks. Data from the monitoring tasks are stored in a database. Analysis of the data that is computationally intensive is generally performed by the inference engines. Wireless network management applications use the framework by installing and running application-specific components (e.g., filters) on the AirMonitors, LandMonitors, and/or inference engines.

摘要： A system and method for link quality routing uses a weighted cumulative expected transmission time path metric. A system for routing in a multi-hop ad hoc network, and a method for measuring the link quality of a route in the network, include assignment of a weight to a link in accordance with an expected transmission time of a packet over the link, and a combining of individual link weights for a route into a path metric. The path metric accounts for interference among links that use a shared channel. In the calculation of the path metric, the expected transmission times of links that interfere with one another are added, while the expected transmission times for non-interfering links are considered separately.

摘要： Techniques for enhancing the throughput capacity available to client devices connected to a wireless local area network (WLAN) are described. Specifically, existing WLAN resources are converted into wireless access points (APs) to create a dense infrastructure of wireless APs. To leverage this dense AP infrastructure, central management techniques are employed. With client-to-AP mapping, these techniques are used to prevent the discovery of multiple APs in a WLAN by a client device and to select a single AP (using certain policies) to associate with the client device and provide it with an enhanced wireless connection to the WLAN. Additionally, techniques are employed to centrally determine, using central policies, when the AP should disassociate from the client device and when another centrally selected AP should respond to, and associate with, the client device to provide it with an enhanced wireless connection to the WLAN—without interrupting/disrupting the client device's access.
