employ large numbers of sensory devices to collect information from the real-world
and to react in observed situations, e.g., smart buildings and smart grids.
In such systems, massive amounts of data need to be collected and processed
in near real-time. This research proposes an efficient method of processing
sensory data by considering that each data transmission and processing is a
task which has to be scheduled for execution to a gateway. The proposed heuristic,
Weighted Minimum Completion Time (WMCT), was compared against five mapping heuristics
by using five efficiency indicators-execution time, makespan, Δ time difference,
solution worth and success rate. The experiments have shown that the WMCT heuristic
outperforms the other methods in terms of the success rate, the solutions
worth and especially, the execution time of the algorithm, while it obtained
good results in regards to the other two efficiency indicators.]]>Alexandrescu, A., I. Agavriloaei and M. Craus,20112011pp: 16Alexandrescu, A. and M. Craus,20102010pp: 112Attiya, G. and Y.
