Prefetching Architecture for Hot-Spotted Network

Source: CiteSeer

ABSTRACT High-speed wireless access networks are studied for future wireless multimedia applications. In such an environment, a mobile host moving with high-speed like a car cannot have enough time for communication as the cell size will be very small and be configured discontinuously. In this paper, we propose a prefetch architecture referred as to Proactive Data Transfer for these networks. In this architecture, cellular network are also utilized for sending data prefetch request, and the data is prefetched at Prefetch Agent located in high-speed wireless networks. Proactive Data Transfer enables a user to start high-speed data communication as soon as she enters into the area. Moreover, throughput deterioration caused by congestion of backbone network can be alleviated. We also show the effect of proactive data transfer by experimentation.

    ABSTRACT: With the proliferation of WiFi technology, many WiFi net- works are accessible from vehicles on the road making ve- hicular WiFi access realistic. However, several challenges exist: long latency to establish connection to a WiFi access point (AP), lossy link performance, and frequent disconnec- tions due to mobility. We argue that people drive on famil- iar routes frequently, and thus the mobility and connectiv- ity related information along their drives can be predicted with good accuracy using historical information - such as GPS tracks with timestamps, RF fingerprints, and link and network-layer addresses of visible APs. We exploit such in- formation to develop new handoff and data transfer strate- gies. The handoff strategy reduces the connection establish- ment latency and also uses pre-scripted handoffs triggered by change in vehicle location. The data transfer strategy speeds up download performance by using prefetching on the APs yet to be encountered. Experimental performance evaluation reveals that the predictability of mobility and connectivity is high enough to be useful in such protocols. In our experiments with a vehicular client accessing road-side APs, the handoff strategy improves download performance by roughly a factor of 2 relative to the state-of-the-art. The data transfer strategy further improves this performance by another factor of 2.5.

    ABSTRACT: This paper proposes an ITS system that uses not only integrated cellular and ad hoc relaying technologies, but also users' mobility profiles. It focuses on a subsystem where cellular bandwidth is used mostly for control signals, and an ad hoc distribution network (ADN) is used for file downloading and video streaming. The paper formulates an optimization problem with the objective being to maximize the amount of data to be delivered to a moving vehicles via the ADN, and thereby minimizing the usage of the costly cellular bandwidth for data transfer. Three approaches based on non-linear and linear programs are described and compared, and simulation results indicate that a satisfying performance for file download applications can be achieved.

    ABSTRACT: This paper proposes a mobile computing prefetching method considering the user’s interest and the common popularity. For mobile computing environments, there exist restrictions as like bandwidth, latency and traffic. Since, in the present, we prefer the united multimedia mobile information service to the voice-based one, these obstacles are regarded as big problems. To solve those problems, a variety of techniquesas well as caching or prefetching have been studied. However most of them are not sufficient in providingthe amount of data that the user wants. We suggest a prefetching method to bring information early by using information about the user’s former interest and the popularity. Comparing to the previous methods in numerical results, the proposed method improves the prefetching performance to give the maximum effectiveness and reduces the failure rate of information searching.
