Algorithm 1 Optimization strategy for reducing the set of transmitted data.

1:
Set $D_{i}^{s} = D$ , for all nodes $i = 1, . . ., n$ , n is designated to smartphone
2:
Calculate accuracy a based-on training set, $D_{i}^{s}, i = 1 . . . n$ and Equation (2)
3:
for each $i = 0 . . . n - 1$ do
4:
for each activity j in $D_{i}^{s}$ do
5:
Calculate accuracy $a_{i, j}$ based on training set and $D_{i}^{s} - j$ and Equation (2)
6:
if $a - a_{i, j} \leq ε$ then
7:
remove activity j from $D_{i}^{s}$ set and go to 2
8:
end if
9:
end for
10:
end for
