Mobile Social Networks (MSNs) aim at forming virtual communities with mobile devices and sharing interest within the community, which has attracted extensive attention in both the academia and the industry in recent years. However, the limited radio coverage and the mobility of users in MSN challenge the design of efficient content delivery schemes. Based on the life regulation of users, this paper proposes a Contact Probability Estimating Model (CPEM) to select the carrier nodes and conduct optimal content forwarding in MSN. Moreover, a Contact Probability based Routing (CPR) protocol is devised to update and share information in a mobile community. Simulation experiments indicate that the CPR proposal is able to provide good performance for an ad hoc MSN in terms of delivery efficiency and reception delay.
移动社交网络(Mobile Social Networks, msn)旨在利用移动设备形成虚拟社区，并在社区内分享兴趣，近年来引起了学术界和工业界的广泛关注。然而，MSN有限的无线电覆盖范围和用户的移动性对高效内容传输方案的设计提出了挑战。基于用户的寿命规律，提出了一种接触概率估计模型(Contact Probability estimation Model, CPEM)来选择MSN中的载体节点，进行内容的最优转发。此外，设计了一种基于接触概率的路由(CPR)协议，用于在移动社区中更新和共享信息。仿真实验表明，该方案在发送效率和接收延迟方面都能提供良好的性能。

In this paper, new training sequence structure with adjustable parameters is proposed for the multiple timing offsets and frequency offsets estimation of cooperative device-to-device (D2D) systems underlaying hyper-cellular networks. By using the proposed training sequences, timing offsets can be estimated using a cross-correlation approach with good performance, and frequency offsets can be estimated using a signal subspace decomposition approach with low complexity. By designing the parameters of the proposed training sequences properly, estimation outliers can be effectively avoided.

Network virtualization is a hot research topic at the moment, and mobile networks are providing services to literally billions of people. Interestingly, the virtualization of complete cellular mobile networks has received little attention up to now, and base station virtualization is a crucial part here. To this end, we propose an architecture for a virtualized base station and examine how the important isolation requirement can be provided for such a base station. We show how resource flexibility can be realized at the radio layer while at the same time keeping a competitive environment intact, and finally present a solution to how the resource assignment to a virtual base station can be verified by the owner of this virtual base station.

Stereoscopic video streaming is emerging as an important technology for future multimedia services. The delivery of real-time high quality three dimensional video to consumers remains a significant challenge due to the scarce resources of the access networks. While real-time rate adaptation has been proposed as a straight forward and easy to deploy method of minimizing transmission losses, its impact on the perceived three dimensional video quality is yet to be studied in depth. This paper investigates the impact of Media Aware Network Element (MANE) on the perceived quality of stereoscopic video measured by Peak Signal to Noise Ratio (PSNR) to both views. Instead of losing packets randomly during the video transmission, the proposed scheme selectively drops packets of the enhancement layers form both views, minimizing the distortion of both views. The Double Exponential Smoothing mechanism is selected for forecasting the transmission data rate. The experimental results indicate that by applying the proposed adaptation scheme, there is a significant improvement on the objectively measured quality of the received video.

Dynamic power management techniques have been proposed in a number of recent approaches to reduce the energy consumption of telecommunication networks and devices. These techniques aimed at finding an optimal trade off between network performance and energy requirements. Control policies using energy-aware routing and traffic engineering can be used in order to extend these techniques to the whole network. However, the deployment of the energy-aware capabilities of heterogeneous networking is still unsystematic and impractical, as a standardized representation is still missing. To overcome such an issue, we introduce a novel framework, the Green Abstraction Layer (GAL), whose goal is to define a multi-layered abstraction interface for the hardware and physical resources. Within the GAL, energy management actions are directly performed. The GAL can be thus exposed to the platform-independent logical representation commonly used in network control protocols. Given the internal architectural complexity and heterogeneity of many network devices, the GAL approach is based on a hierarchical decomposition, where each level provides an abstract and aggregated representation of internal components. The general GAL architecture is currently under consideration for standardization in ETSI.

IP mobility management has a key role in wireless networking and mobile Internet. The existing IP mobility protocols are deployed generally in a centralized manner. All the data traffic passes through a centralized entity and all the bindings are managed at this entity as well. As the number of mobile users and the volume of their traffic increase, such centralized architectures may encounter scalability and performance issues. In order to cope with the rapid increase in mobile Internet traffic, various efforts from both industry and academia are being performed recently on specifying Distributed Mobility Management (DMM). DMM is expected to eliminate the limitations of current mobility protocols. In this paper, we present different DMM approaches based on MIPv6 and PMIPv6, providing global and/or local mobility support. Then, we carry out a qualitative and quantitative analyses. The analyses conclude the strong and weak points of the different approaches, comparing them with existing protocols. Both analyses encourage towards DMM as a promising scheme.

Cloud computation offloading is a promising method that sending heavy computation to resourceful servers on cloud and then receiving the results from them. In this paper, we study the offloading techniques and further explore the tradeoff between shortening execution time and extending battery life of mobile devices. A novel adaptive offloading scheme is proposed and analyzed based on the tradeoff analysis. And it can be realized thanks to the elasticity of cloud computing that the resources can be bought on demand. We have tried to find a server on cloud with a critical value of speedup F for a specified mobile device. When satisfying the requirement such as performance improvement by the system, it is worth sacrificing large F when taking economic factor into consideration.

We present our findings regarding the deployment of 60GHz Gigabit WLAN RoF enterprise networks operating under Medium Transparent-MAC protocols over existing GPON infrastructures. Two possible network scenarios are investigated: i) the GPON-plus-RoF approach considering the 60GHz RoF bus WLAN connected to a conventional GPON ONU, and ii)the RoF-over-PON, which fuses the GPON OLT with the MT-MAC Access Gate at the same Central Office (CO). Simulation-based throughput and delay results are obtained for both network scenarios, revealing the dependence of the 60GHz enterprise network performance on several network planning parameters such as the number of optical wavelengths being available to the enterprise network, the GPON dedicated bandwidth, the load of the enterprise network as well as the percentage of inter- and intra-LAN traffic, highlighting in each case the prevailing architecture.

The performance of communication protocols in vehicular networks highly depends on the mobility pattern. Therefore, one of the most important issues when simulating this kind of protocols is how to properly model vehicular mobility. In this paper we present VACaMobil, a VANET Car Mobility Manager for the OMNeT++ simulator which allows researchers to completely define vehicular mobility by setting the desired average number of vehicles along with its upper and lower bounds. We compare VACaMobil against other common methods employed to generate vehicular mobility. Results clearly show the advantages of the VACaMobil tool when distributing vehicles in a real scenario, becoming one of the best mobility generators to evaluate the performance of different communication protocols and algorithms in VANET environments.

The consumption of video in context of social interactions is becoming reality, as borders between television, video, microblogging and social networking are disappearing. This paper discusses the problem of quality of experience and synchronized video viewing across heterogeneous device and networks ecosystem. The proposed solution, which is still work in progress, builds upon network coding and traffic engineering to achieve maximum goodput across devices and networks, while preserving fairness between flows and meeting quality of experience requirements. The proposed approach has been designed for both real time and non real time content. We present preliminary results for the non-real case, in which the viewers use essentially FTP-like downloads to view and exchange the content.
