MaD-WiSe: Programming and Accessing Data in a Wireless Sensor Networks

G. Amato, P. Baronti, S. Chessa
2005 EUROCON 2005 - The International Conference on "Computer as a Tool"  
MaD-WiSe is a wireless sensor network database designed to perform in-network distributed query processing and to manage acquired data.  ...  This paper briefly presents the MaD-WiSe system and its query processing model based on data streams.  ...  THE MAD-WISE SYSTEM The MaD-WiSe system allows the interaction with a sensor network as a relational database. It consists of two main parts.  ...

Optimizing network-side queries with timestamp-join in wireless sensor networks

Giuseppe Amato, Stefano Chessa, Claudio Vairo
2009 2009 35th Annual Conference of IEEE Industrial Electronics  
This paper proposes a new method for optimizing innetwork distributed queries that perform join of data produced simultaneously by different sensors in a wireless sensor network.  ...  We implemented these join operations in a query processor for mica-class sensors and we performed extensive tests to prove that our approach may reduce energy required to process a long running query,  ...  The MaD-WiSe query parser and optimizer are implemented in Java and run on a standard PC. II.  ...

BackStreamDB: A Distributed System for Backbone Traffic Monitoring Providing Arbitrary Measurements in Real-Time [chapter]

Christian Lyra, Carmem S. Hara, Elias P. Duarte
2012 Lecture Notes in Computer Science  
Monitoring the traffic of wide area networks consisting of several autonomous systems connected through a high-speed backbone is a challenge due to the huge amount of traffic.  ...  Traffic is sampled by monitors that are distributed across the backbone and are accessed by a Stream Processing Engine (SPE).  ...  We thank the Brazilian National Research Network, RNP, for supporting the deployment of the proposed system through Working Group GT-BackStreamDB.  ...
