The Adaptive PSAM Design in Cross-Layer

Wireless Personal Communications, 2008
The purpose is to design the pilot symbols efficiently and adaptively in communication systems to guarantee the minimum channel estimation error and the required quality of service (QoS). The various adaptive schemes about pilot symbols assisted modulation (PSAM) are obtained in terms of the pilot-insertion frequency and the power arrangement.

Cross-layer design for mobile multimedia

2012 21st Annual Wireless and Optical Communications Conference (WOCC), 2012
Mobile multimedia is getting popular. It is expected that 70% of mobile Internet traffic will be video in 2013. Video traffic is so heavy that effective delivery will reduce total amount of Internet traffic as well as your communication fee. This paper argues that cross-layer design will enable the optimal QoE (Quality of Experience) and QoS (Quality ...

A cross-layer design for large transfers in SDNs

2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN), 2016
Software Defined Network (SDN) technologies have enabled the introduction of new services such as dynamic Layer-1 (L1) circuits and Layer-2 (L2) virtual circuits (VCs). This work presents a cross-layer design that leverages transport- and link-layer protocols to enable the full use of high-rate circuits/VCs to achieve high-throughput transfers.

A Survey of Cross-Layer Designs in Wireless Networks

IEEE Communications Surveys & Tutorials, 2014
The strict boundary of the five layers in the TCP/IP network model provides the information encapsulation that enables the standardizing of network communications and makes the implementation of networks convenient in terms of abstract layers. However, the encapsulation results in some side effects, including compromise of QoS, latency, extra overload,

CLOE: Cross-Layer Design for Wireless Networks

2007 IEEE 66th Vehicular Technology Conference, 2007
Cross-layer optimization is an effective mechanism to improve wireless system and network performance and efficiency. Cross-layer optimization is not a new technique, but it can be applied effectively to different wireless technologies to handle different problems without violating the wireless standards.

Cross-layer design for QoS wireless communications

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
An important aspect of wireless networks is dynamic behavior. In this paper, we propose a joint cross-layer design for QoS (Quality of Service) content delivery. Central to our proposed cross-layer design is the concept of adaptation. We propose QoS-awareness scheduler and power adaptation scheme at both uplink and downlink Medium Access Control (MAC ...

Cross-Layer Design of Networked Control Systems

2009 IEEE International Conference on Communications, 2009
The wireless connection of spatially separated sensors, controllers and actuators poses challenging problems to the control system, due to packet drops, delays and measurements quantization, as well as to the wireless network resource allocator. This pushes for a cross-layer design of communication and estimation/control systems.

Cross-Layer Design in Wireless Cognitive Networks

2008 Ninth International Conference on Parallel and Distributed Computing, Applications and Technologies, 2008
The objective of this research is to provide appropriate cross-layer architecture for wireless cognitive networks for efficient resource allocation and improved quality of service. We proposed the blackboard model, which is known for coordinating multiple agents (cognitive nodes) in a real-time manner, receiving the current state of information from ...

Cooperative Cross-Layer Design for Wireless Networks

Journal of Communications, 2008
Cross-layer optimization is an effective mechanism to improve wireless network performance and efficiency. Although cross-layer optimization is not a new technique, it can be applied effectively to different wireless technologies to handle different problems while still conforming to the wireless standards.
