Self-sustaining composed service groups for future internet (invited paper)

The Future Internet will witness a transformation towards service centric communication systems that will closely support the user's requirements. It is anticipated that these services will not only include web services but also multimedia based services, where each service will be developed to focus on certain core functionalities. In order to maximize user's experience, services will have to be composed into groups in order to integrate various functionalities from different services, and maximize the value to the user. Although a number of research have investigated service composition, a core challenge that still needs to be addressed is the ability to efficiently manage the groups to evolve to meet the changing demand of users as well as new service functionalities. In this paper we propose an adaptive "self- sustaining" mechanism for composed service groups based on bio-inspired techniques. The biological mechanisms used include Lotka-Voltera's competition model as well as chemotaxis based search. Simulation results are also presented in this paper to illustrate the mechanism and functionalities of the bio-inspired techniques selected.
