In the numerical models, Arbitrary Lagrangian Eulerian (ALE) description of the liquid structure interface which is described by the mesh nodes at the boundary is employed.
However, the performance of WMNs is still not competitive since the mesh nodes in highly dense urban environments must share the 2.4-GHz industrial, scientific, and medical (ISM) channels with several external devices, primary nodes (PNs), that cannot be governed by the mesh nodes and possibly interfere with the WMNs transmissions.
For the author of this paper [57], they consider the assignment strategy with topology preservation by organizing the mesh nodes with available channels and aim at minimizing the co-channel interference in the network.
First, we ensure interference-free communication among the mesh nodes by ensuring that links within the interference range of each other are assigned different channels.
The TCA-based approach controls the network connectivity by controlling the neighborhoods of the mesh nodes, which leads to less overall transmitted power and better spatial channel reuse.
We provide interference-free communication among the mesh nodes by ensuring that links that fall within the interference range of each other are assigned different non-overlapping frequency channels.
Prior to running any experiments, we used a channel assignment algorithm (see [75]) that automatically assigned channels to the mesh nodes by taking into account both intra-network and external interferences.
Since the objective of multi-path routing is to maximize the total flow in the network by using multiple paths between the mesh nodes and the GW, it returns solutions in which more nodes have high node-degrees, which means more links (conflicts) in the conflict graph.
Three-dimensional environment is meshed with spacing t = 10 m, and the mesh nodes are set as the virtual nodes.
After the new mesh node instance works successfully, old mesh node instance with an old MAC protocol is removed.
