Algorithm 1 Energy-Aware and Secure Task Offloading Algorithm

1:
Initialization: Each task j at UAV i is initialized with the offloading and compression decision as $α_{i j 0} = 1$ and $γ_{i j} = 0$
2:
for all each UAV i and at given time slot t do
3:
for all each task j do
4:
Send requirements for each task and UAV’s capabilities to control the manager through the connected edge servers which includes ${a_{i j}, c_{i j}, d_{i j}, ψ_{i}, c o_{i j}, d e c o_{i j}, p_{i}^{T}, f_{i}^{L}}$ .
5:
end for
6:
end for
7:
Send the available computational capabilities for each edge server and cloud to control manager.
8:
Calculate the rate $R_{i} k$ for each UAV regarding Equation (3).
9:
Derive the values for offloading and compression decisions regarding the formulation in Equation (21).
10:
Transmit these values to UAVs.
