There are many devices embedded in a smart home environment. It is a challenge to operate these devices due to the heterogeneity and the mobility of them. In this paper, we propose a context-aware resource management framework, which aims to (1) discover available resources and update the states of those devices according to the changes of contexts; (2) allocate suitable resources to meet the needs...
We consider geographically distributed data centers forming a collectively managed cloud computing system, hosting multiple Service Oriented Architecture (SOA) based context aware applications, each subject to Service Level Agreements (SLA). The Service Level Agreements for each context aware application require the response time of a certain percentile of the input requests to be less than a specified...
This paper presents a framework for context-driven policy-based QoS control and end-to-end resource management in converged next generation networks. The Converged Networks QoS Framework (CNQF) is being developed within the IU-ATC project, and comprises distributed functional entities whose instances co-ordinate the converged network infrastructure to facilitate scalable and efficient end-to-end QoS...
In the vision of pervasive computing, technology is integrated throughout our environment. Wireless sensor networks (WSNs) provide support for pervasive computing applications through integration of environmental data. We believe that previous approaches to resource management in WSNs are designed to provide support for a specific application and do not adequately support the vision of pervasive computing...
Open Resource Control Architecture (ORCA) is a resource control and management testbed, which provides on-demand resource allocation service. This paper proposes to apply a dynamic, context-aware, computational trust model to ORCA, in which previous behaviors under different operating contexts are used to evaluate the trustworthiness of service manager and site authority actors. This trust model can...
The existence of advanced smart devices and related technologies such as pervasive computing, mobile wireless communications, sensor networks and agent technologies have supported the proliferation of smart spaces. In this paper, we present the design of ??Bosthan??, a multi-agent-based simulation tool that manages resources consumption in multi-inhabitants smart spaces. Bosthan is built on the top...
This paper presents an autonomic system for composing ubiquitous applications at run-time. The applications are composed according to the user preferences collected via a physical user interface. This interface allows users to specify preferences by simple actions of touching with their mobile terminals icons in the environment, instead of explicitly selecting resources and dealing with their properties...
Dissemination control is concerned with controlling electronic resources even after they have been delivered to a legitimate recipient. This paper proposes a secure resource dissemination system framework in which resource providers and recipients are interacted mutually in an anonymous, accountable, and trustworthy way, while security constraints on diverse resources can be continuously protected...
Under web service environment, services' calling or called relationships are usually represented as links. Based on link- or link-content analysis, it may produce tight clusters, which is useful for resource management. However current work only considers the existence of collaboration and it seldom takes service usage context into consideration. In this paper, we suppose to cluster similar services...
In this paper we examine the problem of rich information environments and the need to narrow the agents attention to what is important for them to interact and later to evaluate and transfer reputation values, using attention allocation technique (AA). We also argue that this cannot be done without the aid of service oriented architecture (SOA). Reputation is used in our work as a service, presenting...
With the rapidly increasing interest of citizens and businesses in multimedia group services, personalization, context- awareness and seamless mobility, the communication can no longer be limited to high speed network or devices. In future scenarios, context-aware services and multicasting will together drive a new trend, since context-awareness can exploit situations in which users share the same...
We present a lease-based method for managing various resources in smart spaces. We argue that leases introduce a flexible way of utilizing context information in the management, and thus facilitate the optimization of resource usage. This work-in-progress paper presents our initial concept and methodology, along with ideas for further development
