wherein D is i A decision value indicating whether data currently acquired by the ith mobile edge device has been acquired before; [ S ] i (k)] 2 A binary form representing the kth data collected by the ith mobile edge device; { [ S ] i (k)] 2 } a Representing the a binary number in the binary form of the k-th data collected by the ith mobile edge device; [ S ] i (l)] 2 A binary form representing the ith data collected by the ith mobile edge device; { [ S ] i (l)] 2 } a Representing the a binary number in the binary form of the data collected by the ith mobile edge device for the ith time; g k Is shown asThe number of binary numbers in the binary form of the kth data acquired by the i mobile edge devices; g l The number of binary numbers in the binary form of the ith data acquired by the ith mobile edge device; | | represents taking an absolute value; min () represents finding the minimum value in parentheses;
if D is i If the k time data is 0, the k time data acquired by the ith mobile edge device is acquired before; if D is i Not equal to 0, it means that the kth data acquired by the ith mobile edge device is not acquired before;
the analysis module analyzes whether the currently acquired data is the same as the data stored in the edge server by using the following formula:
Figure FDA0003743418940000041
wherein λ is i A decision value indicating whether the data currently collected by the ith mobile edge device is the same as the data stored in the edge server; [ C (b)] 2 A binary form representing the b-th data stored in the edge server; { [ C (b)] 2 } a Representing the a-th binary number in the binary form of the b-th data stored in the edge server; f b Representing the number of binary numbers in the binary form of the b-th data stored in the edge server; b represents the total number of data stored in the edge server;
if λ i If the current value is 0, the kth data acquired by the ith mobile edge device is the same as the data stored in the edge server;
if λ i And if not, the k-th data collected by the ith mobile edge device is different from the data stored in the edge server.
6. The edge-computed data acquisition device of claim 5, wherein the upload module is further configured to:
and if the currently acquired data is acquired before, not uploading the currently acquired data to the edge server.
