This paper presents a method for packet delivery around voids in ad-hoc networks that use geographic forwarding. The use of local cooperative behaviours to transport packets around network voids features no global coordination. By changing goals, an individual node can create or join in a transient group that generates and holds local knowledge of the void, and which triggers modified behaviour for packet delivery. It is envisaged that additional behaviours may be developed to handle network operation at multiple protocol layers.

In recent years, IT governance has become a key concern issue for senior IT decision makers across various industries. When appropriately implemented, IT governance can play the role of a central nervous system effectively ensuring the well being of the organizational system. The health of the organizational system ultimately contributes to the health of the distributed business ecosystem in which the organization co-exists with other organizations. The underlying goals for adopting formal IT governance practices are improvement of business performance and conformance with regulations. This exploratory study examined how IT governance is implemented in four Australian institutions of higher education through a number of IT governance structures, processes, and relational mechanisms. This paper discusses the importance of these practices as these institutions increasingly compete and collaborate with each other, various government agencies and other research institutions in the digital economy.

Small-medium enterprises (SMEs) gain their strengths from flexible market orientation, agile value chains and cluster-based innovation capacity. The changing global business environment challenges organizations to aim for agility and performance driven management through process focused thinking. For the future collaboration of SMEs with their partners, the agility aim of the Digital Ecosystem paradigm demands for an explicit risk management and collaboration support. This involves an explicit management of the business process by combining continuous process improvement and process reengineering. However, the outcome of process management effort is risky because of the lack of operational information about the future process. The paper analyzes the possible contribution of risk management to support the management of business processes in order to increase the maturity of organizations. The concept is applied in a process simulation example for furniture production. Collaboration support is provided to allow the real-time sharing and interaction of the parties involved, e.g. in case of deviations from the agreed upon target process.

Well defined, loosely coupled services are the basic building blocks of the service-orientated design-integration paradigm. Services are computational elements that expose functionality in a platform independent manner and can be described, published, discovered, orchestrated and consumed across language, platform and organizational borders. Using service-orientation (SO) it is fairly easy to expose existing applications/resources and to aggregate them into novel services called composite services (CS). This aggregation is achieved by defining a workflow that orchestrates the underlying services in a manner consistent with the desired functionality. Since CS can aggregate atomic and other CS, they foster the development of service layers and reuse of already existing functionality. This gave rise to the idea of service networks and consequently service ecologies. In these service ecologies providers and consumers build a self-organizing system across platform and organizational borders, in which resources and business processes are shared. However, the ease with which resources are shared raises concerns in regards to the dependability (e.g. reliability, availability) of the resulting system and consequently the feasibility of service ecologies. This paper focuses on the performance issues that arise when composite services are exposed to transient loads and discusses the need for admission control and adaptive scheduling as a means for improving the performance in service ecologies.

This paper is intended as an analysis of software engineering ontology and to highlight characteristics of software engineering ontology that represent important design considerations for the methodology of multi-site distributed software development. Multi-site teams use software engineering ontology to assist in defining information for the exchange of semantic project information. Some features and functions of the software engineering ontology are also provided. There is no standard graphical ontology representation in the literature so far. In this paper, we also present graphical notations of modelling software engineering ontology as an alternative formalism. The use of the formalism has made it a possible alternative to model the software engineering ontology. The main aim is not only to create a graphical representation making it easier to understand but, importantly, this model should be able to capture the semantic richness of the defined software engineering ontology.

A primary motivation for research in digital ecosystems is the desire to exploit the self-organising properties of natural ecosystems. Ecosystems are thought to be robust, scalable architectures that can automatically solve complex, dynamic problems. However, the biological processes that contribute to these properties have not been made explicit in digital ecosystem research. Here, we discuss how biological properties contribute to the self-organising features of natural ecosystems. These properties include populations of evolving agents, a complex dynamic environment, and spatial distributions which generate local interactions. The potential for exploiting these properties in artificial systems is then considered. An example architecture, the digital business ecosystem (DBE), is considered in detail. Simulation results imply that the DBE performs better at large scales than a comparable service-oriented architecture. These results suggest that incorporating ideas from theoretical ecology can contribute to useful self-organising properties in digital ecosystems.

Knowledge sharing is not a new topic in knowledge management research field. Current research focused on the use of formal ontologies for specifying content-specific agreement for a variety of knowledge sharing activities. In this paper, we choose project organisation as our research domain, due to its geographical issues and cultural issues which may affect knowledge sharing activities occurring in dispersed project groups and group members. Provided by a simple notation system, we propose the project organisation knowledge sharing ontology and validate the conceptual model by realizing in Protege-OWL and SPARQL Query Language.

In a digital business ecosystem environment the trusting agent by analysing beforehand the possible risk in interacting with a probable trusted agent, can make a better decision of its future course of interaction with it. A possible outcome of Risk is the loss to trusting agent's resources involved in the interaction. In a financial interaction, the possible loss that may be incurred is usually the monetary loss in the resources of the trusting agent that are involved in the interaction. In this paper, we propose a methodology by which the trusting agent can determine beforehand the possible Risk in financial terms or the possible loss to its resources as a result of interacting with a probable trusted agent.
