Network deployment in wireless networks implies the distribution of the communication nodes to improve some key operational aspects, such as energy
saving, coverage, connectivity, or simply reducing the network cost. Most
node placement approaches are focused on static scenarios like WSNs, where
the topology of the network does not vary over time. Nevertheless, there exist certain situations in which the network node locations can continuously
change. In this case, the use of special nodes, so-called Relay Nodes (RNs),
contributes to supporting, maintaining or recovering communication in the
network. The present work introduces a multi-stage dynamical RN placement
solution to lead the RNs to their time-varying optimized positions. The approach, named Dynamical Relay Node placement Solution (DRNS), is based
on the use of Particle Swarm Optimization (PSO) algorithms and is inspired
by Model Predictive Control (MPC) techniques following a bi-objective optimization procedure, where both network connectivity and throughput are
jointly maximized. DRNS is validated in both simulated and real environments composed of mobile robotic nodes, the results showing its goodness and operational suitability for real MANET environments.
