This paper presents a distributed cell selection algorithm for energy savings in nomadic networks where randomly distributed devices (e.g., parked vehicles) serve as potential relay nodes. Based on load information and link quality, the nomadic relays and subsequently the users select access points so as to minimize the energy consumption in the network. Furthermore, admission control mechanisms are incorporated at the base stations and nomadic relay nodes to avoid overloading. We prove the convergence of our algorithm, while simulations show that the proposed algorithm has a great potential for reducing the energy consumption compared with traditional cell selection algorithms.
