Quality of Service (QoS) by Utility Evolved Packet Core (EPC) in LTE Network

Network Path and Quality Validation in the Evolved Packet Core

The Internet nowadays plays an imperative role in critical domains such as finance, health, security, entertainment and military where real-time services with guaranteed resources become necessary. Services residing within the application layer in today’s fixed and mobile network environments are abstracting from the underlying network layer, and therefore, assuming pure IP connectivity without...

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...

Instructions for Preparing Camera-ready Manuscripts for

This paper reports on the quality of service (QoS) mapping mechanisms for converged OFDMA-PON and LTE networks to satisfy the stringent QoS requirements. Various options for exhibiting QoS mapping between the LTE bearers and optical OFDMA-PON queues have been presented. These include, wireless classes forwarded directly to one priority optical queue (so called non-mapping mechanism), 1:1 mappin...

Providing QoS in General Packet Radio Service

In this paper we proposed dynamic adaptive guaranteed quality-of-service (QoS) provisioning scheme over General Packet Radio Service (GPRS) wireless mobile links. The guaranteed QoS media access control (GQMAC) protocol and the accompanying adaptive prioritized-handoff call admission control (AP-CAC) protocol are used to maintain QoS guarantees. The effect of mobile handoffs are also taken into...
