The paper presents an IP-based multi-service approach for end-to-end (E2E) Quality of Service
(QoS) provision and discusses it in the context and perspective of the fourth generation (4G) networks.
Particular emphasis is placed on distribution of functionalities between core, edge, multi-access networks and
mobile host. Existing QoS mechanisms are...

In this paper the planar dual-band monopole antenna is presented for Long Term Evolution (LTE) and wireless LAN (WLAN) applications. The design of the proposed antenna is based on Peano fractal curve and meander line structures. The antenna operates in 1.71 GHz to 2.01 GHz in the desired LTE frequency band and 5.0 GHz to 5.5GHz band (IEEE 802.11a b...

... Both networks (LTE and WiFi) are IP-based networks; hence, DiffServ is used to as the main scheme for QoS in IP layer. Moreover, DiffServ also reduces the complexity of the end-to-end QoS across the converged or heterogeneous networks, as recommended by the GSM association (Kubinidze et al., 2004). ...
In this paper, a novel quality of service (QoS) class mapping and scheduling scheme for the LTE-WiFi converged network is proposed to ensure that end-to-end QoS support is provisioned seamlessly. A mapping among QoS classes of LTE and WiFi is performed first, then scheduling scheme is outlined. For scheduling scheme, traffic is separated into real-time (RT) and non-real-time (NRT) components, then a two-stage complex queuing strategy is performed. In the first stage, deficit weighted round robin queuing (DWRRQ) and class-based weighted fair queuing (CBWFQ) are used for RT and NRT applications respectively to segregate and forward traffic according to resource requirements. Whereas in the second stage, rate-control priority queuing (RCPQ) is used for all types of traffic to give each class appropriate priority level. Performance evaluation of the converged network was done based on different metrics such as jitter, end-to-end delay, throughput, and packet loss ratio. Simulation results show significant improvements for RT with slight degradation on NRT applications after using the new scheduling scheme.

Quality of Service (QoS) provision is of fundamental concern in high performance data networks. The system's load and capacity evaluation are dependent on prescribed QoS parameters. The Service Level Agreements among telecom operators focus on their provision. In ubiquitous networks, different technologies with varying architectures and design merge together to enable the make before break concept. In such scenarios, QoS parameters are very critical. The paper presents a QoS enhancement framework for ubiquitous networks aimed at evaluating and routing the received network traffic on basis of intelligently evaluated parameters, enabling the network to perform efficiently.
