Abstract: The existing smart home intrusion detection algorithm has the defects of slow convergence speed and weak anti-interference ability which can weaken the real-time and robustness of decision-making system. By analyzing the characteristics of time domain data and spatial domain evidence, it is concluded that the temporal fusion is focused more on conflict data but more attention is paid to remove conflict data fusion in the spatial domain. Therefore, an adaptive weighted algorithm for temporal fusion and three evidence fusion intrusion detection solution based on modified evidence were proposed. Further analysis is done by applying the algorithm in intelligent house intrusion detection system. Simulations verify that the fusion result of new proposed algorithms not only accelerate the convergence rate and enhance anti-jamming capability comparing with existing algorithms, but also improve the real-time and robustness of intrusion detection system decision-making.
