The evolution and popularization of mobile devices and wireless networks give rise to the creation of a new interaction paradigm, where the devices cooperate to execute short tasks. In this scenario, the problem of how to handle environment changes, which may increase the complexity of distributed mobile applications management and maintenance, needs to be addressed. This paper presents an autonomous and evolutionary model to permit a prompt adaptation of essential services (i.e. message exchange, service description service discovery, service coordination, mobility support and security) to context changes. To validate it, a mathematical model describing the time complexity to diffuse an efficient implementation of an essential service (strategy) taking into account the number of devices is proposed. Finally, the diffusion approach is implemented in a simulator to reason about its impact on the overall efficiency of the essential services and, consequently, the performance of the application.
