An efficient retransmission of data using symbol accumulation wherein the packet received in error is retransmitted at a lower energy-per-bit level concurrently in the same frame with the new packet. The destination device receives the data transmission and retransmission, demodulate the signal, and separates the received data into the new and retransmitted packet. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized since the retransmission of the packet received in error is at a lower energy level than that of the new packet.

A system and method for providing energy-efficient support of continuous aggregate queries in a sensor network by efficiently orchestrating the collection and transmission of data gathered by a collective set of sensors to ensure conformance to a specified QoI bound. To ensure this, the sink communicates a potentially different value of precision range or interval to each individual sensor; the sensor is adapted to only report its samples back to the sink if the sample values fall outside this specified range. An additional way to specify temporally varying precision ranges to an individual sensor or groups of sensors is provided without having to explicitly communicate the precision bounds for these different time instants. Using temporally varying precision ranges permits the exploitation of temporal correlation among the sample values recorded by an individual sensor to further reduce the need for reports from the sensors. This approach is more energy-efficient and improves performance of long-running pervasive environment monitoring applications.
