“…• QoS-reliability is most commonly defined as the percentage of nodes participating in the collection among all the nodes in the sensor network ; Sankarasubramaniam et al (2003)], or as a set of nodes that cover the entire sensor network [Park et al (2004)]. In addition to supporting these reliability specifications, we have developed more informative reliability metrics with well-defined semantics.…”

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 are classified. Two problems and their solutions are then presented as examples to demonstrate how single (or multiple) quality need(s) are satisfied. The paper concludes with suggestions for future research directions that have the potential to complete the framework and provide a holistic approach to sensor applications with diverse quality requirements.

Abstract-This paper presents CORD, a reliable bulk data dissemination protocol for propagating a large data object to all the nodes in a large scale sensor network. Unlike wellknown reliable data dissemination protocols such as Deluge whose primary design criterion is to reduce the latency of object propagation, CORD's primary goal is to minimize energy consumption. To achieve its goals CORD employs a two phase approach in which the object is delivered to a subset of nodes in the network that form a connected dominating set in the first phase, and to the remaining nodes in the second phase. Further, CORD installs a coordinated sleep schedule on the nodes in the network whereby nodes that are not involved in receiving or transmitting data can turn off their radios to reduce their energy consumption. We evaluated the performance of CORD experimentally on both an indoor and outdoor sensor network testbed and via extensive simulations. Our results show that in comparison to Deluge (the de facto network reprogramming protocol for TinyOS) CORD significantly reduces the energy consumption for reliable data dissemination while achieving a comparable latency.

“…Again, the neighborhood information is maintained by periodic gossiping that add additional transport overhead. Garuda [12] provides reliable downstream data broadcast using a minimum dominating set of core nodes, which provides a loss recovery infrastructure for remaining nodes. The overhead incurred by core selection and maintenance in Garuda may make it an expensive solution for dynamic networks.…”

Abstract. Efficient and reliable dissemination of information over a large area is a critical ability of a sensor network for various reasons such as software updates and transferring large data objects (e.g., surveillance images). Thus efficiency of wireless broadcast is an important aspect of sensor network deployment. In this paper, we study FBcast, a new broadcast protocol based on the principles of modern erasure codes. We show that our approach provides high reliability, often considered critical for disseminating codes. In addition FBcast offers limited data confidentiality. For a large network, where every node may not be reachable by the source, we extend FBcast with the idea of repeaters to improve reliable coverage. Simulation results on TOSSIM show that FBcast offers higher reliability with lower number of retransmissions than traditional broadcasts.
