This paper describes a novel software architecture, Competitive Workflow, which implements workflow as a distributed and competitive multi-agent system. The implementation of a competitive workflow architecture designed to model important computer-aided molecular design workflows, the Discovery Bus, is described. QSPR modelling results for three example(More)
The Tracker project is studying rework in systems engineering projects. Our hypothesis is that providing decision makers with information about previous relevant decisions will assist in reducing the amount of rework in a project. We propose an architecture for the flexible integration of the tools implementing the variety of theories and models used in the(More)
A Dynamic Spectrum Management (DSM) Wi-Fi Prototype Platform is described in this paper. The platform hosts a modified 802.11n waveform that operates in TV White Space (TVWS), receives channel lists from a TVWS database, evaluates channel quality, and selects and aggregates data transmitted across up to four noncontiguous channels. The over-the-air (OTA)(More)
Selected Internet Protocol (IP) Traffic Offload (SIPTO) is a feature defined in the 3GPP standards. In this paper we propose a Converged Gateway (CGW) which enables the SIPTO functionality to be performed locally, before data reaches the edge of the Evolved Packet Core (EPC) network. This feature relieves the EPC from high-bandwidth flows that could(More)
Cellular network operators are dealing with the increased data requirements of their customers by attempting to offload traffic from the mobile core network. The 3<sup>rd</sup> Generation Partnership Project (3GPP) standards have defined several strategies that allow for offloading user traffic from the mobile core network. The 3GPP standards also define(More)
