Multiple Range Query Optimization in Spatial Databases
In order to answer efficiently range queries in 2-d R-trees, first we sort queries by means of a space filling curve, then we group them together, and finally pass them for process...

Online Coding for Reliable Data Transfer in Lossy Wireless Sensor Networks
Bulk transport underlies data exfiltration and code update facilities in WSNs, but existing approaches are not designed for highly lossy and variable-quality links. We observe tha...

Low-Complexity SQR-Based Decoding Algorithm for Quasi-Orthogonal Space-Time Block Codes
— In this paper, we propose a new decoding algorithm for quasi-orthogonal space-time block codes (QOSTBCs) which achieves near Maximum Likelihood (ML) performance while substanti...
