摘要： Implementation of opportunistic use of stations in a wireless network as repeaters is described. In one implementation, a station detects the existence of rate anomaly in a wireless network. In response to the rate anomaly, the station may transform into a software repeater for certain other neighboring stations. The repeater function allows for the relaying of packets sent by these neighboring stations to the access point and vice versa. The other neighboring stations, owing to their relative proximity to the repeater station, transmit data at a higher rate to the repeater station. Thus, the removal of the slower stations reduces clogging of the access point and increases the overall data rate within the wireless network. Further, a zero-overhead network coding protocol may be implemented in conjunction with the repeater function to increase capacity of the wireless network.

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： Wireless adapters are installed on one or more general purpose computing devices and are connected via a wireless network in an enterprise environment. The adapters are densely deployed at known locations throughout the environment and are configured as air monitors. The air monitors monitor wireless signals transmitted between transceiver devices and access points and records information about these signals. One or more analysis or inference engines may be deployed to analyze the signals received from the air monitors to obtain optimum performance and connectivity information about the wireless network.

摘要： A method of detecting rogue devices that are coupled to a wired network without generating false negative or false positive alerts is provided. When a wireless monitor detects an observed SSID and/or BSSID, various tests are run to determine whether the observed device is actually coupled to the wired network. To guard against the suspect device spoofing an authorized SSID and/or BSSID, location information is gathered so that the network administrator can pinpoint the location of the rogue device. If the device is not recognized, various other tests are run to determine whether the unrecognized device is actually connected to the wired network. These tests include an association test, a MAC address test, an ARP test, a packet replay test, a correlation test, and/or a DHCP fingerprint test. Once it is determined that the suspect device is a rogue connected to the wired network, an appropriate alert is generated.
摘要翻译： 提供了一种检测耦合到有线网络的恶意设备而不产生假否定或非正警告的方法。 当无线监视器检测到观察到的SSID和/或BSSID时，将进行各种测试以确定观察设备是否实际耦合到有线网络。 为了防范怀疑设备欺骗授权的SSID和/或BSSID，收集位置信息，以便网络管理员可以精确定位流氓设备的位置。 如果设备未识别，则会运行各种其他测试，以确定无法识别的设备是否实际连接到有线网络。 这些测试包括关联测试，MAC地址测试，ARP测试，分组重放测试，相关测试和/或DHCP指纹测试。 一旦确定可疑设备是连接到有线网络的流氓，就产生适当的警报。
