Title: 1. A Context-aware Resource Management Middleware for Service Oriented Applications Based on Cross-Layer Monitoring
Authors: Shudong Chen, Johan Lukkien, Richard Verhoeven
Abstract: Distributed services hosted by electronic devices can be composed into applications using external service orchestration. Since the collaboration involves multiple parties and happens over the Internet, without access control and proper quality of service (QoS) management this type of application is unacceptable. This paper presents VICSDA, a context-aware resource management middleware for service oriented applications, which aims to secure service discovery and access, and to handle the inherent dynamics of services and the network. Devices and services are organized in virtual communities. All activities happen within a virtual community. Only authenticated users are capable to access services and resources. VICSDA accepts application-oriented QoS, gathers statistics of required services and their dynamic resource utilization through a cross-layer monitoring architecture, and updates the service coordination decisions according the real time states of the environment of a running application. For these, two novel services are designed. One is the resource manager which anticipates the performance of both required services and the network and be aware of the environment changes. Another is a device manager which runs on each device and has the fully control of services and their underlying resources. A 3D video streaming application is chosen to prove the feasibility of VICSDA. The system adapts the video encoding parameters and the delivery protocol to the observed capability of the end device and the bandwidth of the channel. Concrete results showed that based on measurable and manageable services, VICSDA is context-aware and can optimize the overall performance of service oriented applications.

Title: 2. Context-Aware Resource Management for End-to-End QoS Provision in Service Oriented Applications
Authors: Shudong Chen, Johan Lukkien, Richard Verhoeven, Pim Vullers, Goran Petrovic
Abstract: Electronic devices admit the composition of applications from distributed services, like shared content, functionality and resources. Without proper management the quality of service (QoS) of this type of application is unacceptable. This paper presents a context-aware resource management middleware for service oriented applications, which aims to handle the inherent dynamics of services and the network. A way to manage the services and resources of a device is presented. Based on measurable and manageable services, this middleware can cope with changes of the environment of an application and optimize its overall performance. User desired application-oriented QoS is specified by an Orchestrator, which orchestrates the collaboration of distributed services to accomplish an application. A resource management service is built to support making dynamic service coordination decisions for the Orchestrator. For this, the resource management service gathers statistics of the required services and their resource utilization over a cross-layer monitoring model. An important aspect for keeping the privacy of the services and controlling the access to resources, all devices and services are organized in virtual communities. Only authenticated users are capable to access services and resources. A free view point 3D video streaming application is chosen to prove the feasibility of the proposed middleware.

Title: 3. Secure Resource Control in Service Oriented Applications
Authors: S. Chen and J. J. Lukkien
Abstract: This paper presents a secure resource control solution for service oriented applications. Through this, resources on a shared device can be protected from malicious abuse and become controllable for special QoS provisioning. Services are grouped into virtual communities and service access can only be done within the scope of a virtual community. Using soft-state management, services and their underlying resources are monitored by a novel device management service which runs on each device and can activate or deactivate hosted services.

Title: 4. Obtaining Resource Controllability in Service Cooperation Environments
Authors: S. Chen and J. J. Lukkien
Abstract: In a ubiquitous computing environment, devices host services that are accessed by anonymous users. This causes threats of resource abuse through malicious attacks or resource scarcity through unintentional excessive service invocations. In this paper, the secure resource control for service sharing is presented which depends on two basic functionalities: access control and soft-state management. Services are grouped into virtual communities for secure access. Service cooperation through external orchestration can only be done within a virtual community. Services can be activated/deactivated by a device management service running on their host devices. Real-time resource utilization of services for virtual community applications is monitored. Therefore, resources on a shared device can be protected from malicious use and become controllable for special quality of service provisioning.

Title: 7. Virtual Community Management for Enabling P2P Services in the IMS Network
Authors: Igor Radovanovic, Johan Lukkien, Shudong Chen, Chris Molanus, Tanir Ozcelebi
Abstract: This paper addresses forming and management of a virtual community (VC) in the IP Multimedia Subsystem (IMS) network. A VC provides scope for mobile peer-to-peer (P2P) service sharing among end users and allows them control of sharing. The paper describes a number of services that enable forming and management of virtual communities and presents several service-oriented system architecture alternatives focusing on distribution of service access control and service discovery control between end users and operators as the owners of the IMS home-networks. Presented architecture alternatives are IMS compatible since they only introduce 5 additional services into the existing IMS architecture. A key service is an orchestrator that exposes new services composed of other services. A proofof- concept realization of the IMS architecture in which control of mobile service sharing is distributed among end users and operators is shown.

Title: 8. Improving TCP/IP Performance over Last-hop Wireless Networks for Streaming Video Delivery
Authors: Igor Radovanovic, Richard Verhoeven, Johan Lukkien
Abstract: This paper discusses a link layer protocol that enhances performance of the Transmission Control Protocol (TCP) over a last-hop wireless network (LHWN) to make it more suitable for delivery of a live video with a short playout deadline. The presented protocol provides preference control of the transmission of video data within the network and it maximizes network goodput (the successfully transmitted amount of useful video data) by maximizing reliability of transmission for a given playout deadline and a varying digital bandwidth. The protocol makes use of the skip function in the TCP receiver [1], [2] to maximize end-to-end throughput of the connection at the expense of reducing full reliability. It can be implemented in a wireless access point to improve quality of the received live video over an Internet connection to an office or home. The main ideas of the protocol are: hide packet losses from the sender by performing local retransmissions based on the information from the video application and according to a certain scheduling policy, drop stale segments before they arrive at the receiver and prevent end-to-end retransmissions of segments received by the access point. The performance of the TCP Reno protocol [3] in combination with both the presented protocol and the skip function in the receiver is compared against the performance of TCP Reno [3], TCP-RTM [2], TCP Reno in combination with Snoop [4] and TCP-RTM in combination with Snoop. The results of simulations show improvement of network goodput across a wide range of packet-error rates.

Title: 13. Prototype of resource-aware and reliable free view point 3D video streaming in virtual communities.
Authors: Shudong Chen, Johan J. Lukkien, Richard Verhoeven, et al.
Abstract: In this demonstrator, multimedia services, including 3D video streaming services and display services are shared then composed into distributed applications in a virtual community. Using the access control of the virtual community, the secure sharing of these services can be achieved. During the 3D video streaming over a fix network and a mobile network, capacity of the delivery channel and resource limitation of the underlying devices are being taken into account. Video encoding protocols can adapt to the real states of these mediums. And delivery protocols are matched with the coded video 3D format to facilitate enhanced reliability and robustness.
