With the recent advancement of vehicular ad-hoc networks (VANETs) or internet vehicles (IoVs), are getting more powerful and generating huge amount traffic data, including computation-intensive delay-sensitive applications in edge computing (VEC) networks, which difficult to be processed by an individual node. These resource-demanding tasks can transferred another node with idle resources for p...

We have seen a rapid increase in mobile data traffic in cellular networks, especially in densely populated areas called “hotspots.” In order to deal with this trend, heterogeneous networks (HetNet) are attracting much attention as a method of effectively accommodating such traffic increases using the Long Term Evolution (LTE)-Advanced system in the 3rd Generation Partnership Project (3GPP). Thi...

The amount of data traffic in cellular networks has been increasing dramatically in the past few decades. To cope with the traffic increase, heterogeneous cellular network has been introduced to improve network performance by offloading traffic to access points (APs) with better link quality. The increase of energy consumption directly increases the greenhouse gas emissions which threatens the ...

The primary design goal of (r)evolutionary NG-PON1&2 was the provisioning of an ever increasing capacity to cope with video-dominated traffic and handle the explosion of mobile data traffic by means of offloading. Recently, however, questions on the future of “post NG-PON2” have surfaced whether to shift its research focus to business and operation related aspects and move access technology int...

OF THE THESIS TCP Servers: A TCP/IP Offloading Architecture for Internet Servers, using Memory-Mapped Communication by Kalpana S Banerjee Thesis Director: Liviu Iftode TCP Server is a system architecture aiming to offload network processing from the host(s) running an Internet server. The TCP Server can be executed on a dedicated processor, node or intelligent network interface using low-overhe...

In broadband access networks, one application may compete for the bandwidth of other applications, thus degrading overall performance. One solution to this problem is to allocate bandwidth to competing flows based on the application type at the gateway of the home network. Unfortunately, applicationbased quality of service (QoS) on a home network gateway faces significant constraints, as commod...

Locally caching contents at the network edge constitutes one of the most disruptive approaches in 5G wireless networks. Reaping the benefits of edge caching hinges on solving a myriad of challenges such as how, what and when to strategically cache contents subject to storage constraints, traffic load, unknown spatio-temporal traffic demands and data sparsity. Motivated by this, we propose a nov...

The limited battery life of modern mobile devices is one of the key problems limiting their use. Even if the offloading of computation onto cloud computing platforms can considerably extend battery duration, it is really hard not only to evaluate the cases where offloading guarantees real advantages on the basis of the requirements of the application in terms of data transfer, computing power n...

Energy consumption of radio access networks is related to the speed and volume of mobile data traffic. Finland aims to achieve two conflicting targets by 2015, the one of 100 Mbps user data rate provision to nearly all citizens and the other of the reduction of Information and Communications Technology industry carbon footprint. The purpose of this paper is to evaluate the energy consumption fo...
