Abstract Within the Fifth Generation framework of dynamic network topology and moving cells, the nomadic node (NN) concept is seen as a promising paradigm to provide coverage extension and capacity improvement on demand as well as to attain reduced capital expenditure and operational expenditure when compared with fixed‐node deployment, such as microcells. This paper proposes an enabling architecture for the NN operation in the framework of a wireless network, and then analyzes the physical layer aspects of the problem and investigates the performance of NN operation in the context of a realistic multi‐cellular wireless network, with the help of site‐specific propagation modeling and real geographical databases. The produced results provide useful insights into the performance of the NN operation; the results show that the NN operation is beneficial both in line‐of‐sight and non‐line‐of‐sight scenarios and demonstrate that the NN selection strategy, which is based on the backhaul signal‐to‐interference‐plus‐noise ratio with a 10 dB power window, offers almost identical performance with the optimum end‐to‐end throughput algorithm.
