This invention relates to assignment of mobile clients (such as mobile telephones or software agents) to mainly stationary servers (such as mobile network base stations or computer servers) with the objective of reducing or minimizing the number of active servers. Once the number of users of a server drops below a specified level, the server may be deactivated resulting in power and efficiency savings. Preferably the method of the invention operates dynamically and during run time. In certain embodiments, the method can accept trade-offs in the quality of service or the number of active servers. In an embodiment of the invention, servers are arranged to 'compete' with adjacent servers for their clients. This competition may be in a self-amplifying manner such that with the effect that more 'popular' servers are more likely to succeed thus resulting in servers which are below a utilization threshold and can therefore be switched off.
