development of agent based cooperative applications using a role based
approach. We focus on the cooperative aspects by introducing cooperation
processes (CP) as a concept of its own. CPs describe all and only the
coordination and cooperation parts of an application. The explicit
documentation of the coordination and cooperation mechanisms used in a MAS
allows their evaluation and reuse. We are able to change existing and introduce
new cooperation processes at runtime without modifying the existing agents. We
specify the cooperative behaviour of an agent in a separate role description.
The interconnection of these roles constitutes the CP. Describing cooperation
independent from concrete agents allows to build heterogeneous, federative and
transformable MAS. We show how agents decide what roles to accept and how the
agent-role interaction works. Finally we present the ROPE framework and runtime
environment.},

abstract = {A great variety of todays networked applications require a reliable multicast
service. A number of the proposed reliable multicast protocols use a positive
acknowledgment scheme, which returns ACKs to the sender to confirm correct
delivery. To avoid the well-known implosion problem in the case of large
receiver groups, often a tree-based approach is used, i.e., receivers are
organized in a tree and ACK messages are passed along the edges of this
so-called ACK tree. For building up this tree variations of the Expanding Ring
Search (ERS) scheme have been proposed. However, our simulations show that ERS
scales poorly. In this paper, we propose an alternative scheme for building up
ACK trees. This scheme is based on a so-called token repository service, where
a token represents the right to connect to a certain node in the corresponding
ACK tree. Nodes that want to join a group just request a token for this group
from the (distributed) token repository service. Our simulations show that our
scheme causes a much lower message overhead than ERS. Moreover, the quality of
the resulting ACK trees in terms of delay and reliability is in many cases
higher if generated with our scheme.},

solves these problems. It provides an infrastructure that is based on computer
models of regions of the physical world, which are augmented by virtual

our platform supports interactions between the computer models and the real

abstract = {To avoid the well-known implosion problem, the majority of reliable multicast
protocols use hierarchical structures to pass acknowledgment messages back to
the sender. In most cases, a technique called expanding ring search (ERS) is
used to construct the acknowledgment tree. In this paper we analyse ERS by
simulation studies. ERS is a simple and fault tolerant approach, but our
simulation results show that it has disadvantages like great reliance on the
multicast routing protocol and poor scalability. If the background load exceeds
a critical level, the message overhead rises exponentially. In this paper, we
will present an alternative approach based on a so-called token repository
service. The token repository service stores a token for each successor, a node
in an ACK tree can accept. To find a node to connect to, the searching node
just retrieves a token from the token repository. We describe how such a
service can be implemented in a way that it can handle a large number of
multicast groups. Our simulation results show that the token repository service
is scalable, independent of the multicast routing protocol and builds
well-shaped ACK trees, causing message delays that are comparable to ERS or
even lower.},

abstract = {Die Rechnerunterst{\"u}tzung von Interaktionen zwischen Menschen wird in
unterschiedlichen Forschungsgebieten untersucht. Das f{\"u}hrt zu einer
vielf{\"a}ltigen, {\"u}berlappenden Begriffsbildung unter den Disziplinen. Die dadurch
bedingte Begriffsverwirrung behindert fach{\"u}bergreifende gemeinsame Entwicklung,
Standardisierung und Wieder- / Weiterverwendung von Ergebnissen. Im folgenden
werden daher breit verwendete Grundbegriffe wie CSCW, Kooperation, Konkurrenz,
Koordination, Kommunikation, Groupware, Workflow-Management, Teleteaching und
Elektronischer Markt geeignet geordnet. Schwerpunkte liegen dabei auf den
m{\"o}glichen Anwendungsgebieten sowie auf den durch Rechner unterst{\"u}tzten
technischen Grundinteraktionen. Damit soll der Beitrag Anwendern und
Entwicklern helfen, f{\"u}r konkrete Anwendungsprobleme Anforderungen ermitteln zu
k{\"o}nnen und Grundelemente in existierenden komplexen Systemen zu identifizieren.},
