This paper describes a user interface for QoS management in mobile IP networks. The paper context is built in conformance with the generic signaling environment, which is standardized by the NSIS IETF working group. In this work, we investigate the use of some techniques of the AI (Artificial Intelligence) domain to implement a user interface called NIA (Negotiation Individual Assistant) in ord...

Guarantees of quality-of-service (QoS) in the real-time transmission of video on the Internet is a challenging task for the success of many video applications. The Internet Engineering Task Force (IETF) has proposed the Guaranteed Service (GS) in the Integrated Service model with firm delay and bandwidth guarantees. For the GS, it is necessary to provide traffic sources with the capability of c...

Support for real time multimedia applications such as, video telephony, financial stock quote services, and multiplayer interactive games etc., is very essential in Mobile Ad hoc Networks (MANETs). Such applications require multiple Quality of Service (QoS) parameters to be satisfied, like bandwidth, end-toend delay, packet loss rate, jitter, etc. This paper considers the problem of finding nod...

Multimedia applications such as video-conferencing, telemedicine, HDTV etc. have very stringent Quality of Service (QoS) demands and require a connection oriented service. For these applications, a path satisfying their requirements in terms of bandwidth, delay, buffer etc. needs to be found. As conventional IP routing is based only on hop counts, it is not suitable for multimedia applications....

With the increased use of IEEE 802.11b wireless networks, there is a strong need to support diverse Quality of Service (QoS) requirements. Recent standardization efforts are being pursued in IEEE 802.11e to introduce a framework for QoS enhancements to the IEEE 802.11b standard. Although IEEE 802.11e provides a level of service differentiation by statically associating different QoS parameters ...

With the growing demand for real time services in wireless Multimedia Sensor Networks (WMSNs), quality of service (QoS) based routing has emerged as an interesting research topic. But offering some QoS guarantee in sensor networks raises significant challenges. The network needs to cope with battery constraints, while providing QoS (end-to-end delay and reliability) guarantees. Designing such Q...

Recently, there has been an increasing trend of research papers in the literature for using the cross layer protocols in the Wireless sensor networks (WSN) domain. Keeping in view these trends in this paper the proposals have been reviewed and an attempt has been done to classify the protocols in order to bring out open issues for researchers. The major challenges in WSN are limited storage, po...

In this paper, we study how to select the transport layer protocol parameters with considerations of wireless link characteristics and application QoS requirements. In our approach, the inter-layer interactions only exchange protocol parameters between layers. We demonstrate that by appropriately selecting the AIMD protocol parameters, AIMD-controlled flows can efficiently utilize wireless reso...

The goal of QoS routing is to find a loopless path through a network that can satisfy a given set of constraints on parameters such as bandwidth, delay and cost. QoS routing algorithms can be classified into three categories. They are Source routing, Distributed routing and Hierarchical routing. In this paper we propose a distributed QoS routing algorithm that gives high call admission rates in...
