This work presents a distributed implementation for processing Maximizing Range Sum (MaxRS) query in Wireless Sensor Networks (WSN). MaxRS query is useful in many spatially-distributed event monitoring and target tracking applications. Given the location and current readings of the nodes, and a rectangle R, MaxRS finds a location of R that maximizes the sum(More)
We present an implementation of a system for managing evolving shapes in Wireless Sensor Networks (WSN). A shape is a contiguous region in which the measurements of the sensors detect values above a given threshold. Our system, in its current version, solves two important problems: (1) Detecting and tracking the changes of boundaries; (2) Detecting an(More)
We address the problem of efficient maintenance of Continuous Maximizing Range-Sum (Co-MaxRS) query for moving objects trajectories. The traditional MaxRS problem aims at finding a placement for a given (axes-parallel) rectangle R so that the number-or the sum of the weights-of objects (points) from a given set O in the interior of R is maximized. However,(More)
