Privacy-Aware Task Assignment for IoT Audit Applications on Collaborative Edge Devices

Algorithm 1

Greedy search-based task assignment.

	Input:
	T: the tasks set; D: the edge devices set; B: the lower bound vector;
	C: the compatibility matrix; E: the evaluation matrix; S: the edge device selection vector.
	Output:
	A: the task assignment matrix.
(1)	for each task tj in T do
(2)	for each edge device di in D do
(3)	if E[i, j] = 1 then
(4)	if S[i] = 1 then;
(5)	skip it and examine the next edge device;
(6)	else
(7)	V ← C[i, j];
(8)	end if
(9)	end if
(10)	end for
(11)	SV ← sorting V based on privacy compatibility degree;
(12)	Select Top-B[j] edge devices from SV;
(13)	Update A[i, j] and S[i];
(14)	end for
(15)	return A;
