Agent placement in wireless embedded systems: Memory space and energy optimizations
(2010)Embedded applications can be structured in terms of mobile agents that are flexibly installed on available nodes. In wireless systems, such nodes typically have limited battery and memory resources; therefore it is important ... -
Algorithms for energy-driven agent placement in wireless embedded systems with memory constraints
(2011)The agent programming paradigm provides an easy to use framework for coding embedded applications in a pervasive environment. Under this model, applications are structured as mobile agents that can be flexibly installed ... -
An area-based overlay architecture for scalable integration of sensor networks
(2010)With many different sensor networks being deployed, there will be an increased need to facilitate their uniform and efficient access at a large, perhaps even global, scale. To this end, we present an overlay-based architecture ... -
Automated context aggregation and file annotation for PAN-based computing
(2007)This paper presents a method for automatically annotating files created on portable devices with contextual metadata. We achieve this through the combination of two system components. One is a context dissemination mechanism ... -
Context-based storage management for wearable and portable devices
(2005)In our information-rich world, managing the data we collect is becoming a significant bottleneck for users. This issue has triggered considerable research in so-called semantic file systems, relying on the attachment of ... -
A demonstration of the NITOS BikesNet framework
(2014)In this paper we present NITOS Bikes Net, a framework for mobile sensing in a city-wide environment offering experimentation capabilities. More Specifically, we present a custom-made and modular prototype device that can ... -

Design and implementation of an extensible architecture for the efficient remote access of simple RFID-readers
(2007)This paper describes a software architecture for the remote monitoring of warehouses equipped with simple RFID reader devices. Its main design objective is to enable a flexible and efficient integration of resource constrained ... -
Distributed Online Algorithms for the Agent Migration Problem in WSNs
(2013)The mobile agent paradigm has been adopted by several systems in the area of wireless sensor networks as it enables a flexible distribution and placement of application components on nodes, at runtime. Most agent placement ... -
EasyHarvest: Supporting the deployment and management of sensing applications on smartphones
(2014)In this paper we present a first prototype of the EasyHarvest framework, which aims to simplify the deployment and controlled execution of large-scale sensing applications on smartphones. On the one hand, application owners ... -
Energy Efficiency through Significance-Based Computing
(2014)An extension of approximate computing, significance-based computing exploits applications' inherent error resiliency and offers a new structural paradigm that strategically relaxes full computational precision to provide ... -
Exploiting co-location history for efficient service selection in ubiquitous computing systems
(2005)As the ubiquitous computing vision materializes, the number and diversity of digital elements in our environment increases. Computing capability comes in various forms and is embedded in different physical objects, ranging ... -
Extracting coarse-grained pipelined parallelism out of sequential applications for parallel processor arrays
(2009)We present development and runtime support for building application specific data processing pipelines out of sequential code, and for executing them on a general purpose platform that features a reconfigurable Parallel ... -
Fast dynamic binary rewriting for flexible thread migration on shared-ISA heterogeneous MPSoCs
(2014)Heterogeneous MPSoCs where different types of cores share a baseline ISA but implement different operational accelerators combine programmability with flexible customization. They hold promise for high performance under ... -
Fast dynamic binary rewriting to support thread migration in shared-ISA asymmetric multicores
(2013)Asymmetric multicore processors have demonstrated a strong potential for improving performance and energy-efficiency. Shared-ISA asymmetric multicore processors overcome pro- grammability problems in disjoint-ISA systems ... -
Formal model and scheduling heuristics for the replica migration problem
(2008)Replication of the most popular objects is often used in distributed data provision systems to reduce access time and improve availability. In fact, a given replica placement scheme may have to be redefined as object ... -
