چکیده

This paper proposes "Proactive Control and Multipath Control" to realize a robust QoS control system for IP-based cellular networks. In these networks, all kinds of traffic will share the same backbone network. This requires a QoS system that differentiates services according to the required quality. Though DiffServ is thought to be a promising technique for achieving QoS, a technique that is proof against rapid traffic changes and an effective path control scheme are not yet available. Our solution is proactive control using traffic anomaly detection and multipath control using linear optimization. Simulation results show that proactive control and multipath control improve system performance in terms of throughput and packet loss when rapid traffic change takes place.

A Fuzzy Based Three Color Meter/Marker for Diffserv Networks (RESEARCH NOTE)

Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF,‏ meters an IP packet stream and marks its packets either green, yellow, or red....

A Novel Fuzzy Logic Base Scheduling Mechanism for Service Differentiation in IP Networks

Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...

A New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions

Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...

Robust network dimensioning for realtime services over IP networks with traffic deviation

Network planning for realtime services in traditional systems is normally performed based on a fixed traffic demand. Realtime services such as voice and video are currently being widely deployed over packet-based IP networks. Due to the lack of resource control mechanisms in IP networks, the actual traffic during network operation may easily deviate from the given mean traffic matrix values. As...

Wireless Multimedia in 3G networks

This chapter describes the support for IP based multimedia services on Third Generation (3G) wireless cellular networks. While earlier cellular networks offered only basic IP connectivity on a best-effort basis, 3G networks provide explicit support for real time multimedia services with guaranteed Quality of Service (QoS). As a result, they can offer traditional voice telephony, rich telephony ...
