Edan, N. M., Al-Sherbaz, A., Turner, S. J. and Ajit, S. (2016) Drawbacks of Inter-Asterisk Exchange protocol in V.VoIP. In: IEEE Computing Conference 2017. IEEE. 

Abstract

There is a lot of interest in the use of multimedia protocols over Internet, especially in terms of quality of service and signalling, such as the IAX2 protocol. This paper aims to identify the limitations of the IAX2 protocol in a real world implementation of V.VoIP, primarily of its quality of video calls, based on an Asterisk server. Including the contradictions in the IAX2 standard and compare it with its related work over various issues, such as quality of service, security, codecs, port, frames, etc. This work will interest to developers in order to make them aware of the current IAX2 issues.

Design of performance-aware resilient wireless NoC architectures

Opoku Agyeman, M., Wen, Z., Kanakis, T., Tong, K.-F. and Mak, T. (2016) Towards the practical design of performance-aware resilient wireless NoC architectures. In: 7th International Conference on Cloud Computing, Data Science & Engineering. USA: IEEE. 


Abstract
Recently, an improved surface wave-enabled communication fabric has been proposed to solve the reliability issues of emerging hybrid wired-wireless Network-on-Chip (WiNoC) architectures. Thus, providing a promising solution to the performance and scalability demands of the fast-paced technological growth towards exascale and Big-Data processing on future System-on-Chip (SoC) design. However, WiNoCs trade-off optimized performance for cost by restricting the number of area and power hungry wireless nodes. Consequently, in this paper, we propose a low-latency adaptive router with a low-complexity single-cycle bypassing mechanism to alleviate the performance degradation due to the slow wired routers in such emerging hyhbrid NoCs. The proposed router is able to redistribute traffic in the network to alleviate average packet latency at both low and high traffic conditions. As a second contribution the paper presents an experimental evaluation of a practically implemented surface wave communication fabric. By reducing the latency between the wired nodes and wireless nodes the proposed router can improve performance efficiency in terms of average packet delay by an average of 50% in WiNoCs.

SDQ: Software Defined Networking experimentation framework

Fawcett, L., Mu, M., Broadbent, M., Hart, N. and Race, N. (2016) SDQ: enabling rapid QoE experimentation using Software Defined Networking. In: IFIP/IEEE International Symposium on Integrated Network Management. New York: IEEE. (Accepted)

Abstract
The emerging network paradigm of Software Defined Networking (SDN) has been increasingly adopted to improve the Quality of Experiences (QoE) across multiple HTTP adaptive streaming (HAS) instances. However, there is currently a gap between research and reality in this field. QoE models, which offer user-level context to network management processes, are often tested in a simulation environment. Such environments do not consider the effects that network protocols, client programs, and other real world factors may have on the outcomes. Ultimately, this can lead to models not functioning as expected in real networks. On the other hand, setting up an experiment that reflects reality is a time consuming process requiring expert knowledge. This paper shares designs and guidelines of an SDN experimentation framework (SDQ), which offers rapid evaluation of QoE models using real network infrastructures.

An analytical channel model for emerging wireless Networks-on-Chip. 

IEEE/IFIP International Conference on Embedded and Ubiquitous Computing (EUC 2016). 

France: IEEE Computer Society

Abstract
Recently wireless Networks-on-Chip (WiNoCs) have been proposed to overcome the scalability and performance limitations of traditional multi-hop wired NoC architectures. However, the adaptation of wireless technology for on-chip communication is still in its infancy. Consequently, several challenges such as simulation and design tools that consider the technological constraints imposed by the wireless channel are yet to be addressed. To this end, in this paper, we propose and efficient channel model for WiNoCs which takes into account practical issues and constraints of the propagation medium, such as transmission frequency, operating temperature, ambient pressure and distance between the on-chip antennas. The proposed channel model demonstrates that total path loss of the wireless channel in WiNoCs suffers from not only dielectric propagation loss (DPL) but also molecular absorption attenuation (MAA) which reduces the reliability of the system.

Abstract
To meet the performance and scalability demands of the fast-paced technological growth towards exascale and Big-Data processing with the performance bottleneck of conventional metal based interconnects, alternative interconnect fabrics such as inhomogeneous three dimensional integrated Network-on-Chip (3D NoC) has emanated as a cost-effective solution for emerging multi-core design. However, these interconnects trade-off optimized performance for cost by restricting the number of area and power hungry 3D routers. Consequently, in this paper, we propose a low-latency adaptive router with a low-complexity single-cycle bypassing mechanism to alleviate the performance degradation due to the slow 2D routers in inhomogeneous 3D NoCs. By combining the low-complexity bypassing technique with adaptive routing, the proposed router is able to balance the traffic in the network to reduce the average packet latency under various traffic loads. Simulation shows that, the proposed router can reduce the average packet delay by an average of 45% in 3D NoCs.

An analytical channel model for emerging wireless Networks-on-Chip

Abstract
Recently wireless Networks-on-Chip (WiNoCs) have been proposed to overcome the scalability and performance limitations of traditional multi-hop wired NoC architectures. However, the adaptation of wireless technology for on-chip communication is still in its infancy. Consequently, several challenges such as simulation and design tools that consider the technological constraints imposed by the wireless channel are yet to be addressed. To this end, in this paper, we propose and efficient channel model for WiNoCs which takes into account practical issues and constraints of the propagation medium, such as transmission frequency, operating temperature, ambient pressure and distance between the on-chip antennas. The proposed channel model demonstrates that total path loss of the wireless channel in WiNoCs suffers from not only dielectric propagation loss (DPL) but also molecular absorption attenuation (MAA) which reduces the reliability of the system.

Abstract

The vast growths in mobile and wireless applications would contain lacks of using suitable security concepts during the development process which worries the information security research community. This paper reviews most of the encryption techniques which adopt chaos based cryptography, and illustrates the used of chaos based voice encryption techniques in wireless communication as well. The review in this paper summarized the traditional and modern techniques of voice/speech encryption and demonstrated the feasibility of adopting chaos based cryptography for in wireless communications.
