Recent studies have preliminarily investigated and proven the feasibility and effectiveness of applying Content Centric Networking (CCN) principles to Mobile Ad-hoc Networks (MANETs) for content-oriented wireless communications in infrastructure-less mobile environments. However, existing designs may not achieve the full potential of CCN-MANETs. In this paper, we develop a content-centric communication...
Recent popularity of mobile devices increased the demand for mobile network services and applications that require minimal delay. 5G mobile networks are expected to provide much lesser delay than the present mobile networks. One of the conventional ways for decreasing the latency is caching the content closer to the end user. However, currently deployed methods are not effective enough. In this work-in-progress...
In recent years, as higher performance terminal equipments are spread, the amount of mobile data traffic is growing rapidly by using popularization of streaming services in wireless networks. To overcome this situation, it is considered that Access Points (APs) are deployed densely for capacity improvement. In such an environment, virtualization is a possible technique to use multiple APs efficiently...
Mobile Crowdsensing is a promising paradigm for ubiquitous sensing, which explores the tremendous data collected by mobile smart devices with prominent spatial-temporal coverage. As a fundamental property of Mobile Crowdsensing Systems, temporally recruited mobile users can provide agile, fine-grained, and economical sensing labors, however their self-interest cannot guarantee the quality of the sensing...
The consideration of mobile web page and service access for optimization schemes requires a detailed interpretation that goes beyond the commonplace evaluations of HTTP-delivered objects. Evaluating mobile browser interactions with popular web sites, we note that a non-negligible amount of data is delivered with HTTPS and web site interactions could almost exclusively rely on HTTPS delivery of their...
Opportunistic Mobile Social Networks (MSNs) are a type of delay-tolerant networks that are composed of mobile nodes with social characteristics. Most of current research on forwarding algorithms for MSNs leverages the properties of social networks, such as community and centrality. However, the fundamental property, interaction, has not received sufficient attention. The effects of interactions consist...
Mobile devices and wearables are becoming more popular everyday. Such devices are equipped with advanced hardware and software capabilities. While delegation and remote delivery of services for mobile and wearable devices are not new, such services are limited to framework specific applications, and, without a defined incentive model for cooperative service delivery. In this paper, we propose the...
Mobile Cloud Computing enables resource limited mobile devices to support rich application services. Among three types of cloud services, Infrastructure-as-a-Service (IaaS) clouds provides compute infrastructure for mobile applications on demand. In IaaS-based mobile clouds, latency and bandwidth requirements can considered as critical factors impacting Quality of Service (QoS). Opposed to centralized...
This paper presents an online algorithm for mobile user speed estimation in 3GPP Long Term Evolution (LTE)/LTE-Advanced (LTE-A) networks. The proposed method leverages on uplink (UL) sounding reference signal (SRS) power measurements performed at the base station, also known as eNodeB (eNB), and remains effective even under large sampling period. Extensive performance evaluation of the proposed algorithm...
The ubiquitous adoption of cellular technologies, such as, Long Term Evolution (LTE) and Wide-band Code Division Multiple Access (WCDMA) has not diminished the impact of Global System for Mobile communication (GSM) technologies. Despite 20 years of deployment, GSM still poses significant security threats to its users due to adversaries exploiting protocol vulnerabilities. In this paper, we present...
Data traffic has been increasing rapidly in recent years on mobile networks. Several methods using unlicensed bands for LTE are proposed to increase wireless capacity. Stand-alone unlicensed LTE is also proposed as a technology that provides LTE service with only unlicensed bands. In this paper, we propose distributed P-GW systems for stand-alone unlicensed LTE base stations that can provide future...
Development of the Next Generation Networks is ongoing process. The research community is focused on development of 5G network that will assure advanced communication. Solutions are argued on daily basis and are expected to be finalized around 2020. In this paper, we present an advanced transport protocol, designed to assure efficient data usage in the future 5G mobile networks. This transport protocol...
The evolution of the Internet of Things (IoT) has brought new security requirements in terms of communication services with respect to data transmitted in mobile networks. Although IoT middleware systems have been used to cope with the most relevant requirements demanded by different IoT applications, security is a special topic that is not mature enough in this kind of technology. E-health is an...
Due to dynamic wireless network conditions and heterogeneous mobile web content complexities, web-based content services in mobile network environments always suffer from long loading time. The new HTTP/2.0 protocol only adopts one single TCP connection, but recent research reveals that in real mobile environments, web downloading using single connection will experience long idle time and low bandwidth...
Lack of network availability or limited access to communication services are among the challenges that public safety officials and first responders could face during disasters. Networking infrastructure can partially (or sometimes fully) breakdown during a catastrophe. At the same time, unusual peaks in traffic load could lead to much higher blocking probability for critical communication. A possible...
