A WDM optical layer can provide differentiated services to various upper layer protocols by forming many virtual optical networks (VONs). Polymorphic control of an optical layer in the form of On-demand-reconfiguration in some VONs and Self-reconfiguration in other VONs is proposed. The former is suitable for bursty traffic and short-lived connections, and the latter is for steady traffic and l...

In this paper, we address the issue of motion planning for a bipartite class of modular self-reconfiguring robotic system (I-Cubes) that is a collection of active elements providing reconfiguration (3-DOF manipulators called links) and passive elements acting as connectors (cubes). The links, capable of attaching/detaching themselves from/to cubes, can position and orient the cubes. Current sol...

Reconfiguration of radial distribution networks is the basis of supply restoration after faults and of load balancing and loss minimization. The ability to automatically reconfigure the network quickly and efficiently is a key feature of autonomous and self-healing networks, an important part of the future vision of Smart Grids. We address the reconfiguration problem for outage recovery, where ...

Complex technical systems, such as mechatronic systems, can exploit the computational power available today to achieve an automatic improvement of the technical system performance at run-time by means of selfoptimization. To realize this vision appropriate means for the design of such systems are required. To support self-optimization it is not enough just to permit to alter some free parameter...

Adaptively evolvable systems require some reconfigurable capabilities, habituated within the FPGA. FPGA’s can be integrated with either Dynamic Partial Reconfiguration (DPR) or Virtual Reconfiguration Circuits (VRC). Since DPR allows lesser resource utilization on the FPGA available logic, which has a positive repercussion in power consumption compared to VRC’s, we are using FPGA’s with native ...

We aim at merging technologies from Information Technology, Roomware, and Robotics in order to design adaptive and intelligent furniture. This paper presents the framework for modular robots, called Roombots, as future building blocks for furniture that moves and self-reconfigures. The reconfiguration is done using dynamic connection and disconnection of modules and rotations of the degrees of ...

Architecting in the context of variability has become a real need in todays software development. Modern software systems and their architecture must adapt dynamically to events coming from the environment (e.g., workload requested by users, changes in functionality) and the execution platform (e.g., resource availability). Component-based architectures have shown to be very suited for self-ada...

Reconfigurable architectures such as FPGAs are a key technology for implementing self-adaptive and flexible systems, since the possibility for dynamic and partial hardware reconfiguration offers a higher degree of freedom in the resource allocation. However, for many applications, modern reconfigurable architectures cause too high power consumption. For this reason, FPGAs are typically used in ...

This paper proposes a novel end-to-end QoS framework, called Self-Adaptive bandwidth Reconfiguration QoS framework (SAR). SAR provides end-to-end QoS guarantees on a per-flow basis through admission control and end-to-end bandwidth reservation. In order to adapt to short and long time traffic load changing, SAR performs dynamic bandwidth reconfiguration. Due to a new organization of the network...
