The femtocell concept is an emerging technology for deploying the next generation of the wireless networks, aiming at indoor coverage enhancement, increasing capacity, and offloading the overlay macrocell traffic. Nevertheless, one of the most critical issues in femtocells deployment is the potential interference, thus mitigating the overall system capacity. Inspired by the cognitive radio tech...

Cloud radio access network (C-RAN) and Mobile Cloud Computing (MCC) have emerged as promising candidates for the next generation access network techniques. MCC offers resource limited mobile devices to offload computationally intensive tasks to the cloud, while C-RAN offers a technology that addresses increasing mobile traffic. In this paper, we propose a protocol that allows task offloading an...

In this paper, we present and evaluate the effect of two mode selection schemes for device to device (D2D) enabled areal netwroks. The two schemes are based on a threshold received signal strength (RSS) and an average threshold D2D distance between two given users to select the D2D mode. While one scheme triggers the D2D mode based on distance values only, the other scheme can trigger D2D mode ...

This paper addresses the bottleneck of the conventional video streaming using the client-server approach, and an innovative centralized peer-to-peer approach is proposed. In order to achieve the best perceived quality of service, combination of layered source coding and distributed network adaptation is proposed in this paper. The proposed technique features centralized management, guaranteed p...

The base motivation of Mobile Cloud Computing was empowering mobile devices by application offloading onto powerful cloud resources. However, this goal can’t entirely be reached because of the high offloading cost imposed by the long physical distance between the mobile device and the cloud. To address this issue, we propose an application offloading onto a nearby mobile cloud composed of the m...

The vertical handover decision strategy in the heterogeneous wireless networks is very challenging issue because it needs to deal with many different radio access networks and make decisions for vertical handover calls between them. Due to traffic offloading the decisions for vertical handovers to WLAN hotspots in heterogeneous wireless networks are very important because they impact the QoS of...

Due to the explosion of smart devices, data traffic over cellular networks has seen an exponential rise in recent years. This increase in mobile data traffic has caused an immediate need for offloading traffic from operators. Device-to-Device(D2D) communication is a promising solution to boost the capacity of cellular networks and alleviate the heavy burden on backhaul links. However, dir...

Mobile computation offloading means transfer of execution of mobile software computation outside of the actual device. In this paper, we use a context-driven approach to analyse and design offloading systems. We conduct a literature survey of the types of offloading, supportive architectural models and existing frameworks to propose taxonomies of mobile offloading from viewpoints of an overall ...

As the main gateway for network traffic to a server, the network interface card (NIC) is an ideal place to incorporate diverse network functionality, such as traffic control, protocol offloading, and virtualization. However, the slow evolution and inherent inflexibility of NIC hardware have failed to support evolving protocols, emerging applications, and rapidly changing system/network architec...
