    Abstract: A sensor profile based data aggregation method for aggregating data in a sensor network, which includes a plurality of sensor nodes, is provided. This method includes steps of determining types of sensors included in the sensor nodes, and generating a sensor profile that includes information on each type of the sensors. The information includes a filtering criterion and aggregation operators defined for the each type of the sensors. Once the sensor profile is created, the profile is parsed into a header file, and the header file is compiled with other sub-modules to generate a sensor profile based aggregation module. The sensor profile based aggregation module is installed in each of the sensor nodes. Whenever, sensor data is received in the sensor node, the data is filtered according to the filtering criterion defined in the sensor profile, and data aggregation is simultaneously with given operators.

    Abstract: A small office/home office base transceiver station (SOHO BTS) server capable of managing interference by correlating pilot strength measurements sent by mobile devices and directing the attenuation settings for each transmit path. An array of antennas coupled to an array of transmit paths are selectively activated one at a time. When a transmit path is activated, the SOHO BTS server sets the associated variable attenuator to its maximum level. The SOHO BTS server detects whether a radio environment report or and a pilot strength measurement message (PSMM) containing information about a mobile station's pilot strength is present. When the pilot strength is greater than a predetermined value, the SOHO BTS server increases the setting on the attenuator. Otherwise, the SOHO BTS server decreases the attenuator setting until such pilot strength information is available or if the lowest attenuator setting has been set. The other transmit paths are also tested accordingly.

The mobile station further comprises an interference estimator that receives W detected user signals from the first detector and outputs W estimated interference signals to the W subtractors.

    Abstract: In a multiple-input, multiple-output (MIMO) enabled mesh network, streams for transmitting data from a node to a destination node are controlled based on next hop latency and available stream capacity at neighboring, next hop nodes. Routing information maintained and dynamically updated at each node includes latency information associated with each next hop for transmission from the node to a given destination node and current available stream capacity for such next hop nodes. A controller at the node utilizes that information to select one or more next hop nodes to which the data is forwarded as well as to determine a number of streams that may be initiated with each selected next hop node.
