Efficient Energy Management in Networking

In the last couple of decades, we have witnessed major technological changes that have transformed the way we live, work, and interact with one another. One of the major technology facilitator in charge of for this remarkable transformation in our global society is the deployment and use of Information and Communication Technology (ICT) equipment. In fact, today with the current pandemic going on ICT has become highly integrated in our society that includes the dependence on ICT of various sectors, such as business, transportation, education, and the economy to the point that we now almost completely depend on it. In the last few years, the energy consumption resulting from the usage of ICT equipment and its impact on the environment have resulted in a lot of interests among researchers, designers, manufacturers, policy makers, and educators. Hence energy efficiency has become important bar that is being increasingly used to evaluate energy consumption of devices, hardware and various networking architectures, systems, and communication protocols. I will cover the same and present some of the motivations driving the need for energy-efficient communications in this paper. There have been a lot of approaches to minimize energy consumption by communication devices, protocols, networks, end-user systems, and data centers and I will describe and discuss some of the recent techniques and solutions that have been proposed to minimize energy consumption, also look to the future of networking from a new angle, where energy efficiency and environmental concerns are viewed as fundamental design criteria and forces that need to be harnessed to continually create more powerful networking equipment.

Leveraging Software-Defined Networking Approach for Future Information-Centric Networking Enhancement

Information-centric networking (ICN) has been developed as a potential candidate for future networks. In this model, users are provided with content rather than communication channels between the different hosts. The ICN network has several problems such as scalability issues and bandwidth consumption. However, software-defined networking (SDN) has been proposed to improve the networking architectures. The goal of our paper is to propose a new approach to named-data networking (NDN) based on the paradigm of SDN. Our work introduces various research studies carried out in the SDN and ICN contexts. We first present the SDN architecture. Then, we focus on work that combines ICN and SDN architectures. Finally, we show the effects of using the SDN architecture on the named-data network (NDN). Our experimental results show that the use of the SDN architecture has a positive effect on NDN network performance.

Improve Performance (QoS) in Wireless Sensor Networks Using TCP/IP Protocol

Unattended devices may provide high resolution information about sensed phenomena at the point where sensors are arranged together. There has been a great surge of interest in WSN in recent years, concentrating on developing the required hardware, software, and networking architectures to enable such applications. A broad variety of heterogeneous remote entities and the current IP-based internet should be merged into one ubiquitous network in the ideal 4G worldview to provide transparent consumer connectivity. As a relative of the remote network, the sensor network should be organized and all IP systems will not be able to manage this new development in this work, given the main difficulties in the auxiliary architecture of IP-based and sensor systems. TCP/IP has been the genuine conventional suite for the organization of wired networks. The easiest and most convenient way to deal with TCP/IP interface systems and sensor systems is to use TCP/IP.

Future SDN-Based Network Architectures

The goal of this chapter is to provide a clear view of SDN, its origin, and its possible future. This chapter starts by taking a step backwards and looks at SDN in a historic perspective by visiting the history of network programmability and identifies how it helped pave the way and shape SDN. This historic journey will provide a general context of SDN and put SDN into perspective. Then the authors show the current view of SDN as defined by standard development organizations (SDOs), provide a sense of SDN's malleability, explore SDN interactions with different networking architectures, and finally, provide a vision of a possible SDN future.

Placement of Controllers in Software Defined Networking under Multiple Controller Mapping

This work focuses on the placement of controllers in software-defined networking architectures. A mathematical model is developed to place controllers under multi- controller switch-controller mapping, where a switch can be assigned to multiple controllers. Resiliency, scalability, and inter-plane latency are all modeled in the proposed model. A scalability factor is introduced to increase the load to capacity gap at controllers, preventing controllers to work near their capacity limit. The proposed model is shown to be effective and resilient under different failure scenarios while, at the same time, taking latency and scalability into consideration.
