CDS-based Multi-regional Query Processing

9.5 Performance Evaluation
In this section, we compare the performance of MRQSA with the centralized version
of DCQS denoted by C-DCQS proposed in [157]. C-DCQS is the most recently
published algorithm that solves the multi-query scheduling problem. We compare
the two algorithms in terms of latency under three different scenarios. Since energy
consumption is still one of the primary concerns in WSNs, the performance of our
proposed MRQSA in terms of energy consumption is evaluated as well.
9.5.1 Simulation Environment
In our simulations, we deploy sensor nodes in a monitoring area of 1000 m×1000 m,
where ...
