Abstract:
Traditional software development relies on building and assembling pieces of software in order to satisfy explicit
requirements. Component-based software engineering simplifies composition and reuse, but software
adaptation to the environment remains a challenge. Opportunistic composition is a new approach for building
and re-building software in open and dynamic contexts. It is based on the ability to compose software components
in a bottom-up manner, merely because they are available at a point and not because the construction
of a specific software has been demanded. In this way, software emerges from the environment. This paper
analyzes the advantages of such an approach in terms of flexibility and reuse, along with the requirements that
an infrastructure supporting opportunistic composition should satisfy: it should be decentralized, autonomic,
and dynamically adaptive. The state of the art of automatic software composition shows that few solutions are
actually bottom-up, and th
at none of them fully satisfies the requirements of opportunistic composition.
