Quality-aware sensor data collection

Abstract: Many sensor applications often require to collect raw sensed values from many sensor nodes to one centralized server. Sensor data collection typically comes with various quality requirements, e.g., the level of precision requested for temperature values, the time constraints for getting the data, or the percentage of data that is needed. This paper presents a quality-aware sensing framework where characterization of sensor applications' quality needs are identified and different sensor data collection problems… Show more

“…Just as QoS serves as the operational and management centrepiece of distributed systems today, QoI with its many dimensions can serve as the operational and management centrepiece of the systems of tomorrow. For an early example of linking QoS with aspects of QoI in data collection systems, see [95]. This would require a holistic approach to research on QoI and its implication to system operation and impact on end users.…”

“…Manzoor [62] associates a weight to each context attribute to represent its importance and computes completeness as the ratio of the sum of the weights of the available attributes to the total of the weights of all the attributes of a context object. Han et al [44] define a reliability criterion as the minimum number --of sensor data that should be collected within some time units. Filho [37] redefines completeness to integrate timeliness so as to avoid unnecessary computa tions and manipulate only current context information.…”

“…First, DGPB seeks the Pareto-optimal routing structures with respect to multiple conflicting optimization objectives such as data yield, latency and energy consumption. Since optimization objectives often conflict with each other in WSNs [3], it is important to examine the optimal trade-offs (i.e., Pareto optima) among those objectives. However, as discussed in Section 5, no existing data gathering protocols do not study that.…”
