Space and satellite systems are considered to be the most extreme environment to design for and are fraught with engineering difficulty. Performance metrics such as fault tolerance, reliability, pre-determinism and heritage are still high of the list of requirements for all missions. But withthe advent of modern day electronics, greater computing capability and networking technologies have enabled research into distributed satellite systems, where multiple spacecraft work collaboratively to perform a mission. Leveraging from these technologies, a satellite can be considered one of many nodes in an autonomous system. this paper proposes the use of an Agent based computing platform to solve orbit dynamics problems leading to a highly mobile and decentralized system. the latest Agent platforms are compared and possible Agent applications are presented;specifically, distributed image compression and a novel topology reconfiguration scheme.

A wide range of high-performance distributed embedded systems have been designed and deployed. Physically distributed embedded systems are used for manufacturing and control, traffic analysis, and other problems. Interestingly, today's systems-on-chips are sufficiently complex that they must be treated as distributed embedded systems. At all scales of physical extent, middleware is required to manage the computations. this paper looks at distributed embedded systems at several physical scales and considers the types of middleware that are needed to operate these systems.

In this paper, a Role-based Access Control (RBAC) model is applied and extended to a multimedia version called Multi-Role Based Access Control (MRBAC), which can fully support the comprehensive and multilevel security control requirements of the distributed multimedia applications. the object-oriented concept is adopted in MRBAC to perform the hybrid role hierarchy management and security roles and rules administration. In summary, MRBAC can: 1) support the multi-level security protection for multimedia data;2) provide access control by checking boththe time constrains and IP addresses;and 3) decentralize the administration functions to make the access control management more efficient.

the technology supporting Multiplayer Online Games (MOGs) has greatly improved in the past few years. this represents great news both for players all over the world and for researchers that are struggling behind tough problems in real-timedistributed systems. Indeed, MOGs represent a peculiar class of distributed systems, sharing features, requirements, challenges, and thereby also feasible solutions. To this aim, we focus on issues and state-of-art solutions related to a crucial aspect in MOG deployment: the synchronization of its nodes. In particular, we review techniques able to guarantee that the system evolves in a quick and consistent way and highlight how they can be made more effective by exploiting specific game features. To further support this claim, we also present results from an experimental evaluation we performed.
