Users can connect to the network from ubiquitous points of attachment and wireless portable devices can roam by maintaining continuous connectivity. Novel middleware technologies based on code mobility has the potential to enhance service provisioning to mobile users/devices. However, code mobility adds complexity to the design of applications and calls for new approaches for the programming of code mobility strategies. Separation between mobility and computational concerns is crucial to reduce the complexity of code mobility control and to favor rapid mobile code-based service prototyping, run-time configuration and maintenance. To achieve the needed degree of separation of concerns the paper advocates the adoption of policies and proposes a policy-based framework for dynamic code mobility management. In addition, the paper explores a reflective-based approach to mobility control and compares policy with reflective-based programming solutions to point out the main differences and lessons learned.","PeriodicalId":173397,"journal":{"name":"Proceedings 27th Annual International Computer Software and Applications Conference.

It is relatively easy to describe a pattern of interaction, or choreography, in the case where everything proceeds smoothly. However, the abnormal cases, such as where a process fails or a message is lost, are much more complicated, and risk introducing data and process inconsistencies into computer-based systems. Current B2Bi technologies do not supply an infrastructure that can provide reliability without considerable sophistication from the architects and developers. As a first step towards guiding architects to the design of B2Bi systems that maintain consistency despite failures, this paper describes a variety of types of failure that can arise in practice, based on a realistic e-procurement scenario. We describe these failures in terms of the different types of state that naturally occur within the distributed system. Understanding the types of failure that need to be handled, or prevented, is essential to an architect or developer who must design and write handlers for all the exceptions that can occur in their workflows.","PeriodicalId":173397,"journal":{"name":"Proceedings 27th Annual International Computer Software and Applications Conference.

In order to make the mobile agent paradigm more useful and acceptable for Web and Internet applications, the security considerations should go beyond the protection of basic agent execution environments. In this paper, we present the design of a robust Java-based mobile agent system, PeAgent. The PeAgent system not only incorporates a fine-grain agent privilege control mechanism, but also includes a multi-level protection mechanism that can be used throughout the life-cycle of agents. A two-level domain hierarchy is constructed to organize the large number of Internet nodes in the agent system into manageable units: the global/domain management unit (GMU/DMU). Each unit consists of a certification authority (CA) and a location manager (LM). The certificates issued from GMU and DMU define the access privileges on the PeAgent servers for each agent. A context hierarchy is built up on the PeAgent servers for fine-level resource access control and agent management. Overall, the PeAgent system provides a secure computing environment for widely distributed applications over a network of heterogeneous platforms. It also facilitates the development of secure Web-based applications.","PeriodicalId":173397,"journal":{"name":"Proceedings 27th Annual International Computer Software and Applications Conference.
