development of SHSs. An MAS reduces the total compu-
tational and data transmission time of the total system which
results in reduced energy consumption.

control of smart homes [30], smart home security systems
based on object detection [31], gesture controlling features
for elderly people [32], and smart home antitheft systems
[29]. Since these image processing systems are dependent on
real-time videos and images from the smart home, image
processing-based SHSs generally have a high rate of data
transmission between the camera and the data processing
section. Image processing has been utilized by several au-
thors because of its wide range of functions, from antitheft
systems to elderly support. However, since cameras are
afected by shadows, distortions, insufcient light, and other
factors, the image processing system sometimes fails to
deliver the expected result.
