摘要： Disclosed is a method for determining the placement of ITAPs in wireless neighborhood networks. The method disclosed provides for efficient integration of multi-hop wireless networks with the Internet by placing ITAPs at strategic locations. Initially the method provides for the formulation of the ITAP placement problem under three wireless models. For each model, methods are developed to efficiently place ITAPs in the networks. The methods aim to minimize the number of required ITAPs while guaranteeing users' bandwidth requirements. Next, a fault tolerance version of the placement method is presented that provides bandwidth guarantees in the presence of failures. Finally the methods are extended to take into account variable traffic demands by developing an approximation algorithm to simultaneously optimize ITAP placement based on demands over multiple periods.

摘要： Systems and methods are described for detecting and diagnosing performance problems in wireless communications networks. Diagnostic programs execute on a wireless device, neighboring devices, and a wireless access point to collaborate in diagnosing network problems. The neighboring devices eavesdrop on a diagnostic session between the device and the access point to determine problems at the device, the access point, and in the wireless medium. Data from the eavesdropping devices can be summarized and sent to a network administrator for further action. The diagnostic programs are described to contain a passive component for detecting problems, and an active component for running the diagnostic techniques.

摘要： Methods are described for using collaboration of neighboring wireless devices to enable location of disconnected wireless devices and rogue wireless access points. A central server computes the locations of the neighboring clients and uses those locations to estimate the location of a disconnected client. These techniques may take advantage of the beaconing and probing mechanisms of IEEE 802.11 to ensure that connected clients do not pay unnecessary overheads for detecting disconnected clients. Methods are also described for detecting and locating rogue devices by collaboratively collecting information from neighboring devices and comparing the information to a database.

摘要： Methods for optimizing battery use for a known future load are described. In an embodiment, one or more battery cells are selected from a set of battery cells to provide power to a computing-based device. The battery cells are selected based on discharge profile data for each battery cell and both the current power requirement and a known future power requirement of the computing-based device. The known future power requirement is calculated based on information available to the operating system running on the computing-based device. In some examples, one or more battery cells may also be selected for charging when a power source is available and these cells may be selected based on charge profile data and the known future power requirement. The selection of the battery cells may also be made in order to satisfy a battery optimization goal, which may be defined by a user.
