This paper describes an adaptive network infrastructure, Composable Adaptive Network Services (CANS), for bridging the bandwidth and resource gap between network services and mobile clients. CANS enables construction of service access paths augmented with ‘impedance matching’ components that handle operations such as caching, protocol conversion, and content transcoding. The CANS infrastructure...

The importance of reconfiguration service in Wireless Sensor Network (WSN) has driven many researchers to develop various ways to reduce incurred costs in software maintenance on sensor nodes. However, the lack of utilization of software engineering methodologies in previous studies can cause numerous efforts to configure the WSN for each site and modification of the system to introduce additio...

Title of Document: TOPOLOGY CONTROL AND POINTING IN FREE SPACE OPTICAL NETWORKS Yohan Shim, Doctor of Philosophy, 2007 Directed By: Associate Professor Steven A. Gabriel Department of Civil and Environmental Engineering Free space optical (FSO) communication provides functionalities that are different from fiber optic networks and omnidirectional radio-frequency (RF) wireless communications in ...

Self-optimization is a promising approach to cope with the increasing complexity of today’s automation networks. The high complexity is mainly caused by a rising amount of network nodes and increasing real-time requirements. Dynamic hardware reconfiguration is a key technology for selfoptimizing systems, enabling, e.g., Real-Time Communication Systems (RCOS) that adapt to varying requirements a...

Companies are nowadays placed in very complex and dynamic environments, making their competitiveness mandatory. This competitiveness can also be achieved through the reconfiguration of systems’ network. In this paper, high level of self-organization of service-oriented multi-agent systems is explored, aiming to achieve more trustworthy and automatic reconfiguration processes, in dynamic and ope...

Consider a redundant ring network where each node is also connected to the nodes at distance d. In the presence of faulty nodes, the goal of a reconfiguration scheme is to construct the largest subring among the non-faulty nodes using both regular and bypass links. If the faults partition the network into components, such a subring will be entirely within a component. The set of faulty nodes de...

This paper presents a novel approach for optimal reconfiguration of radial distribution systems. Optimal reconfiguration involves the selection of the best set of branches to be opened, one each from each loop, such that the resulting radial distribution system gets the desired performance. In this paper an algorithm is proposed based on simple heuristic rules and identified an effective switch...

The dynamic and partial reconfiguration of FPGAs enables the dynamic placement in reconfigurable zones of the tasks that describe an application. However, the dynamic management of the tasks impacts the communications since tasks are not present in the FPGA during all computation time. So, the task manager should ensure the allocation of each new task and their interconnection which is performe...

When evolved NodeB (eNB) flexible functional split is implemented in Virtualized Radio Access Network (V-RAN) 5G systems, fronthaul connectivity between the virtualized network functions (VNFs) must be seamlessly guaranteed. This study proposes the utilization of Software Defined Networking (SDN) to control the mobile fronthaul. In particular, this study investigates the ability of the SDN-base...
