Efficient design and implementation of LTE UE link-Layer Protocol stack
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013Co-Authors: Manli Qian, Y.b Huang, Yiqing Zhou, Yuanyuan Wang, Wei Wei, Jinglin ShiAbstract:3GPP Long Term Evolution (LTE) and its enhancement has become the main candidate of 4G standards. Due to the requirements on high data rate and low latency for broadband wireless communication systems, LTE air-interface Protocol stack must be designed and implemented with high data processing efficiency. Following a general description of the LTE user equipment (TIE), this paper analyzes the main challenges in the link-Layer Protocol stack design and implementation, including the data processing efficiency, synchronization, flexibility and portability. A reference design of LTE TIE link-Layer Protocol stack software is then presented with several design methodologies. A memory access optimization and light-weighted thread model are proposed to improve the data processing efficiency, while a hardware triggered synchronization mechanism is exploited to maintain synchronous between the link-Layer Protocol stack and the physical Layer. Finally, the platform flexibility and portability is achieved by employing interface abstraction and adapters. Extensive system level testing shows that the proposed LTE TIE Protocol stack software achieves high data rate and low data processing latency in a hardware resource restricted platform, which can be further extended to commercial LTE TIE products.

design and implementation of an application Layer Protocol for reducing udp traffic based on user hints and policies
Lecture Notes in Computer Science, 2002Co-Authors: William Kulju, Hanan LutfiyyaAbstract:This paper presents an application-Layer Protocol for UDP that makes use of user hints (e.g., a screen saver being invoked or covering a window with another) to reduce network traffic, which in turn may help reduce congestion. The architectural components used to implement the application-Layer Protocol can generally be applied to a reduction in resource (e.g., CPU) consumption. We present an architecture and experimental results.

Experimental Evaluation of an Industrial Application Layer Protocol Over Wireless Systems
IEEE Transactions on Industrial Informatics, 2007Co-Authors: Stefano Vitturi, Iacopo Carreras, Daniele Miorandi, Luca Schenato, A. SonaAbstract:Several recent studies have addressed the suitability of current wireless technologies for industrial communications which, frequently, are requested to cope with severe timing constraints. Most of the analysis that have lately appeared in the literature have focused on the performance offered by the lower Layers of the communication stack. However, in order to obtain a complete picture, it is important to analyze how this gets coupled with the features of higher Layer Protocols typically employed by industrial communication applications. In this paper, we investigate the performance obtained by an application Layer Protocol, derived from those currently employed by wired fieldbuses, running over COTS devices based on two popular wireless communication standards, namely, IEEE 802.15.4 and IEEE 802.11. In particular, we present a mapping of the application service elements onto the services offered by the mentioned wireless systems and discuss some possible design choices. A prototype of the application Layer Protocol is then implemented for each considered wireless technology and the performance figures evaluated by means of experimental measurements.

performance of an application Layer Protocol for wireless industrial communications
Emerging Technologies and Factory Automation, 2006Co-Authors: Iacopo Carreras, Daniele Miorandi, Stefano VitturiAbstract:Current wireless technologies offer a viable solution for implementing communication systems capable of satisfying the severe timing requirements often required for operations at the lowest levels of factory automation systems. Most of the contributions appeared in the literature on this subject aimed at investigating the suitability to industrial applications of some wireless communication Protocols. In this paper, we address the problem from a different perspective. Namely, we are interested in characterizing the application Layer performance of a field-bus Protocol running over an IEEE 802.11g-based wireless LAN. We provide a preliminary Java-based implementation of such application Protocol, and test it on laptops running a Linux operating system and off-the-shelf 802.11 cards. The performance of the application Layer Protocol are extensively tested on an experimental system characterized by environmental conditions similar to those of industrial installations.
