- Bluetooth Device Manager Connecting a Large Number of Resource-Constraint Devices in a Service-Oriented Bluetooth Network
- The unique advantages of Bluetooth such as low power consumption capability, cheap hardware interfaces and easy set-up offer new application areas. This is a reason why Bluetooth is even considered for a Service Oriented Architectures SOAs consisting of a large number of resource-constraint devices. Although several proposals are available for...

- Authoring Constraint-Based Tutors in ASPIRE
- This paper presents a project the goal of which is to develop ASPIRE, a complete authoring and deployment environment for constraint-based Intelligent Tutoring Systems ITSs. ASPIRE is based on the previous work on constraint-based tutors and WETAS, the tutoring shell. ASPIRE consists of the authoring server (ASPIRE-Author), which enables domain...

- An Expressive Constraint Language for Semantic Web Applications
- The semantic web vision is to enable rich machine-processing of web information sources. This paper presents a framework for semantic web applications based on constraint interchange and processing. At the core of the framework is a well-established semantic data model (P/FDM) with an associated expressive constraint language Colan. To allow...

- Resource Management for Global Public Computing: Many Policies Are Better Than (N)one
- The federation of authority in global public computing systems poses major resource management challenges, as different stakeholders may have different views on how server resources are to be apportioned. Ultimately, the complexity of declaring and managing potentially overlapping federated policies often leads to the absence of high-level resource management systems...

- Supporting Collaboration Through Semantic-Based Workflow and Constraint Solving
- This paper describes the efforts to provide a collaborative problem solving architecture driven by semantic-based workflow orchestration and constraint problem solving. These technologies are based on a shared ontology that allows two open systems of very different natures to communicate, perform specialised tasks and achieve common goals. The paper gives...

- Model-Based Resource Prediction for Multi-Hop Wireless Networks
- Ad hoc networks have been proposed for a variety of applications where support for real time, multimedia services may be necessary. This requires that the network is able to offer Quality of Service QoS appropriate for the latency and throughput bounds needed to meet the real time constraint. An important...

- An Evaluation of Heuristics for SLA Based Parallel Job Scheduling
- In the context of SLA based job scheduling for high performance grid computing, this paper investigates the behaviour of various scheduling heuristics to schedule SLA-bounded jobs onto a parallel computing resource. The key objective of this investigation is to evaluate the effectiveness of simple scheduling heuristics using as criteria the...

- Hop-by-Hop Congestion Control Over a Wireless Multi-Hop Network
- This paper focuses on congestion control over multihop, wireless networks. In a wireless network, an important constraint that arises is that due to the MAC Media Access Control layer. Many wireless MACs use a time-division strategy for channel access, where, at any point in space, the physical channel can be...

- The IBM Research Constraint Solver Models and Solves Complex Problems Through the Examination and Prioritization of Myriad Variables and Constraints
- Variables can be a headache. Ask any seventh grader puzzling over a2=9. When variables for a given problem include the myriad manufactured parts that make a truck engine run or the skill sets of thousands of employees, the capabilities of the human mind can be overwhelmed. Enter the IBM Research...

- Constraint-Based Routing in the Internet: Basic Principles and Recent Research
- Novel routing paradigms based on policies, Quality of Service QoS requirements, and packet content has been proposed for the Internet over the last decade. Constraint-based routing algorithms select a routing path satisfying constraints which are either administrative-oriented policy routing, or service-oriented QoS routing. The routes, in addition to satisfying constraints,...

- Dimensioning an Inbound Call Center Using Constraint Programming
- One of the critical problems in the call center industries is the staffing problem since they must face variable demands and because staff costs represent a major part of the costs of this industry. The problem of dimensioning a call center is modeled as a particular scheduling problem, where the...

- An Explanation-Based, Visual Debugger for Spreadsheet-Like Constraints
- This paper describes a domain-specific debugger for one-way constraint solvers. The debugger makes use of several new techniques. First, the debugger displays only a portion of the dataflow graph, called a constraint slice, that is directly related to an incorrect variable. This technique helps the debugger scale to a system...

- Use the concept of the triple constraint to manage client expectations
- Think of a project as a three-legged stool. If one of the "legs" is decreased or increased, the remaining legs much do the same. Have you ever been on a project where the client was eager to add more and more features, but not so eager to add...
