Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This paper explores the challenges of delivering quality-of-service (QoS) support for streaming media services in ad hoc group communication networks. It aims to develop a novel scheme, QASAN, that effectively addresses these challenges and ensures efficient and reliable delivery of media content in dynamic environments. The paper focuses on the importance of QoS for streaming services in mobile ad hoc networks, especially considering the impact of mobility, QoS support, and multicasting.

• Quality of Service (QoS) in Ad Hoc Networks
• Streaming Media Services in Group Communication
• Multicasting and Resource Management
• QoS-aware Routing and Policy Management
• Performance Evaluation and Experimental Validation

Zusammenfassung der Kapitel (Chapter Summaries)

The introduction outlines the importance of QoS routing for multimedia distribution in high-speed networks and highlights the challenges of guaranteeing QoS in mobile ad hoc environments. It discusses the limitations of existing QoS protocols and introduces the concept of Soft QoS as a potential solution for handling dynamic network conditions.

Chapter II provides a comprehensive review of existing research related to QoS routing and group communication in ad hoc networks. It analyzes the challenges and shortcomings of existing protocols, such as AODV and TORA, and emphasizes the need for more robust and efficient solutions.

Chapter III presents the proposed QASAN architecture, which addresses the challenges of QoS provisioning for streaming services in ad hoc group communication networks. It describes the key components of QASAN, including its group creation and modification mechanisms, and the role of the QASAN Policy Manager (OPTIQ_Policy) in ensuring QoS guarantees.

Chapter IV delves into the details of the QASAN Policy Manager (OPTIQ_Policy) and its negotiation procedures. It outlines the policies used for resource allocation and reservation, focusing on the optimization of QoS for various types of streaming services.

Chapter V discusses the simulation evaluation metrics used to assess the performance of QASAN. It examines the aspects of capacity estimation, delay estimation, admission control, and resource reservation, highlighting the importance of these factors in achieving reliable QoS for streaming services.
