Understanding user behavior of mobile Internet is vital for network infrastructure planning and radio resource allocation. In this paper, we investigate the spatial-temporal characteristics of users' access behavior and mobility patterns based on a data set collected from a cellular network in a city of China. We first propose a method called Maximum Distance Criterion (MDC) to distinguish users'...
Licensed-Assisted Access (LAA) using Long Term Evolution (LTE) is a promising solution to alleviate the problem of scarce spectrum resources by extending to the unlicensed band. However, co-existence mechanisms should be carefully taken into consideration to provide fair co-existence to other LAA and 802.11 based Wi-Fi networks that operate on the same unlicensed carrier. In this paper, we focus on...
The tremendous popularity of smart phones and electronic tablets has spurred the explosive growth of high-rate multimedia wireless services. To alleviate the huge infrastructure investment in the exponential growth of mobile traffic and improve local service flexibility, device-to-device (D2D) communications have been considered for the next generation mobile telecommunications. This has triggered...
Node mobility in a vehicular network is strongly affected by driving behaviour, such as the choice of route. Although various route choice models have been studied in the transportation community, the effects of preferred routes on vehicular networks have not been discussed much in the networking literature. In this work, we set out to understand the effects of different parameters, such as route...
As the mobile Internet gradually penetrates into the daily life, it is becoming the most important way people acquire information. Statistical characteristics of users' data access behavior can be used as the foundation for optimization of network deployment, or even trigger new business models. In this paper, distribution patterns of the subscriber's data access behavior have been discussed both...
Previously, a multi-homed NEMO architecture has been proposed to improve the reliability and aggregate the bandwidth of MR by simultaneously using multiple wireless links. In this work, we propose a novel protocol called ETOM (Enhancements for TCP On a Multi-homed mobile router) to improve the performance of sending a single TCP connection over multiple wireless links on a MR. ETOM consists of three...
In this paper, we investigate the mobile P2P file-sharing problem, and proposed a mobile P2P content distribution architecture. Due to mobile specific influence factors, a hybrid architecture has been employed. We assume that the P2P mobile terminal can publish, index and retrieve resources on the Index Server, and collect the real-time state and cache content resource through Resource Management...
Vehicular Network is becoming increasingly popular in recent years, in which vehicles constitute a wireless mobile network. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) are two different modes of communication in a vehicular network. Some measurement studies have previously been undertaken to understand the feasibility of using WiFi for V2V and V2I communication. Recently WiMAX is...
A novel fast link establishment method based on the combination with Multi protocol Label Switch (MPLS) and mobile agents(MA) for handoff during the mobile IP communication proceeding is proposed. By using the mobile agents for fast automatically information transforming the method can reduce the delay time dramatically. Simulations show that the transmission delay can be reduced to 27 to 41 percents...
