Special issue on mobile social networks

Social networks contribute a significant fraction of Internet traffic, and increasingly this traffic is in support of mobile social networking using smart phones. This situation has spurred considerable recentresearch interest in mobile social networks. Social networks have been studied for decades, although most of the earlier work in this area addressed issues lying outside the scope of technological networks. […]

Virtual device passthrough for high speed VM networking

Supporting network I/O at high packet rates in virtual machines is fundamental for the deployment ofCloud data centers and Network Function Virtualization. Historically, SR-IOV and hardwarepassthrough were thought as the only viable solution to reduce the high cost of virtualization. In previous work [15] we showed how even plain device emulation can achieve VM-to-VM speeds of millions of packets […]

Exploring Stock Market Using Twitter Trust Network

As social networks are becoming more and more popular, more and more data are available from them. Researchers are now trying to extract useful information from these big data. One possible usage of social media is to investigate stock market. There are two major events to measure in stock market – price change and trade […]

Digging the innate reliability of wireless networked systems

Network reliability of wireless networks exhibits a prominent impact in successful advancement of the networking paradigm. A complete understanding of the network reliability demands its in-depth analysis, which is yet to be attempted in the literature. Therefore, we present a comprehensive study on the network reliability in this paper. Our step-by-step stochastic study, from node-level to […]

A home cloud-based home network auto-configuration using SDN

In recent years, the prevalence of network devices such as smartphones, smart appliances, and various sensors has increased. As a result, interest in and demand for home networks has steadily increased. So, auto-configuration problems in home networks are very important and must be addressed, because some household members will not be familiar with the Information Technology (IT) devices […]

Improving spam detection in Online Social Networks

Online Social Networks (OSNs) are deemed to be the most sought-after societal tool used by the masses world over to communicate and transmit information. Our dependence on these platforms for seeking opinions, news, updates, etc. is increasing. While it is true that OSNs have become a new medium for dissemination of information, at the same […]

A measurement model for trustworthiness of information on social network services

Due to the spread of unreliable online information on social network services (SNS), the users are faced with a difficult problem for determining if the information is trustworthy or not. At present, the users should make a decision overall by themselves for trustworthiness of information. Therefore, we need a way to systematically evaluate trustworthiness of information on […]

CoopRED: Cooperative RED for software defined networks

Recently, Internet is an essential part for human life, and several problems lead Future Internet. Software Defined Networks (SDN) is a representative approach in Future Internet. We propose Cooperative Random Early Detection (CoopRED) to avoid inefficiency in core routers when incoming traffic generates congestion. Our scheme selects packets that will be dropped in the bottleneck link, and […]

A Dynamic Networking Substrate for Distributed MMOGs

This paper proposes a distributed and dynamic networking architecture for massively multiplayer online games (MMOGs). The MMOG networks deal with the challenge of update message exchange among a large number of players that are subject to both mobility (constant change of virtual location) and churn (joining and leaving the physical network at will). Ideally, a player’s update […]

On Availability-Performability Tradeoff in Wireless Mesh Networks

It is understood from past decade of research that a wireless multi-hop network can achieve maximum network throughput only when its nodes operate at a minimum common transmission power level that ensures network connectivity (availability). This point of optimality where maximum availability and throughput is guaranteed in an interference-optimal network has been the basis of numerous design […]
