Abstract: Provided are methods and systems for creating an optimal set of reflector peers, comprising detecting a plurality of reflector peers, retrieving a plurality of static metrics from each of the plurality of reflector peers, ranking the plurality of reflector peers based on the plurality of static metrics, selecting a top predetermined number of peers from each static metric, establishing the selected reflector peers as the optimal set of reflector peers, determining dynamic metric for each of the plurality of reflector peers, and adjusting the optimal set of reflector peers based on the dynamic metric.

Abstract: A method is provided for managing a location sensing operation for location-based applications, including activating a first sensor disposed in the portable device so as to provide a location sensing operation requested by at least one location-based application. The method further includes periodically monitoring movement of the portable device by a second sensor disposed in the portable device, and suppressing the location sensing operation of the first sensor in accordance with the movement of the portable device detected by the second sensor.

Abstract: Provided are methods and systems for multi-caching. The methods and systems provided can enhance network content delivery performance in terms of reduced response time and increased throughput, and can reduce communication overhead by decreasing the amount of data that have to be transmitted over the communication paths.

Abstract: A method and apparatus for communicating over a network is provided. The method includes selecting between location-sensing methods for an LBA, such as between GPS and network triangulation. For each location-sensing method, a dynamic determination is made as to whether the accuracy of the location-sensing method, in the current environment, meets the application requirements. If two or more location-sensing methods meet the application requirements, then, location-sensing method selected is the location-sensing method that, from among the location-sensing methods that meet the application requirement, consumes the least power. Otherwise, the location-sensing method that is most accurate for the current environment is selected.
