  Network Nonlocality is an advanced study of quantum nonlocality that
comprises network structure beyond Bell's theorem. The development of quantum
networks has the potential to bring a lot of technological applications in
sevaral quantum information processing tasks. Here, we are focusing on how the
role of the independence of the measurement choices of the end parties in a
network works and can be used to enhance the security in a quantum network. In
both three-parties two-sources bilocal network and four-parties three-sources
star network scenarios, we are able to show, a practical way to understand the
relaxation of the assumptions to enhance a real security protocol if someone
wants to breach in a network communications. Theoratically, we have proved that
by relaxing the independence of the measurement choices of only one end party
we can create a Standard Network Nonlocality(SNN) and more stronger Full
Network Nonlocality(FNN) and we can get maximum quantum violation by the
classical no-signalling local model. We are able to distinguish between two
types of network nonlocality in the sense that the FNN is stronger than SNN,
i.e., FNN states all the sources in a network need to distribute nonlocal
resources.
