Selbstorganisation durch dezentrale Koordination in Verteilten Systemen

DFG Normalprogramm (In cooperation with HAW Hamburg)

Abstract

In order to meet the increasing demand for scalable, robust and adaptive distributed systems self-organized software systems have been proposed and identified as a key issue within computer science research. Here, "self-organization" describes physical, biological and social phenomena, where new global structures arise from the local interactions of individuals. Therefore, the SodekoVS project addresses the purposeful utilization of self-organizing dynamics to explicitly engineer adaptive, distributed software systems. It aims at both new concepts as well as corresponding generic system support for supporting highly autonomous distributed applications. The SodekoVS project is conducted jointly with the Hamburg University of Applied Sciences (HAW).

In a first project phase, a process catalogue was establisher based on systematic modelling of decentralized coordination processes; furthermore, it could be demonstrated how the various established mechanisms for self organisation could be uniquely described in a common coordination language and, consequently, realized as software. For integrating the so described coordination processes, a generic software architecture was developed which automates strict separation of coordination and applications logic and also most of all necessary coordination activities. Thus, self-organising processes can be jointly used as optional and re-usable elements in a common conceptional framework. The development methodology necessary for that was formalized as a Software & Systems Process Engineering Meta model Specification (SPEM) which demonstrates the feasibility of a method for systematic development of such software systems, for which self-organization processes can be used for realising the above mentioned systems characteristics.

The second project phase addressed mainly two further essential aspects of such system development: First, system simulation is a necessary part of developing self-organizing processes; therefore, this project phase also addressed two main steps for that: namely the execution and evaluation of system simulations - systematically prepared for mostly automatic execution. A second important aspect for improving the usability of the approach use automatic execution time adaptation of system configurations. Finally, some application studies demonstrated and evaluated the applicability of methods and concepts as proposed by this project. In summary, this demonstrated that the overall goal of the project (i.e. better using benefits of self-organization for software development) could be reached to a high degree based on concepts, methods, and the system platform as proposed by this project.
