“…The work in [10] measures radio channels and analyzes general channel characteristics using statistical analysis. The work in [11] takes a statistical analysis approach to optimal design in mobile satellite broadcast systems. The proposed scheme in [12] performs QoS mapping between the application level and the user level by multiple regression analysis, which is a statistical analysis method.…”

We focus on mobile P2P multicast, in which mobile end nodes not only act as receivers but also relay the received stream forward to others. In mobile P2P multicast, negative effects caused by the change of available bandwidth and the disconnection of mobile nodes are propagated to the downstream nodes. To solve this problem, we developed a novel node-allocation framework using the multidimensional context parameters of each mobile node, which include available bandwidth, disconnection rate, and the remaining battery capacity. Considering the significance of each parameter, our method integrates these parameters into a single parameter called relay ability. Taking the relay ability into account, each node is allocated to the multicast topology to minimize the negative effects mentioned above. To test our method, we applied our framework to conventional P2P multicast topology and show the results from comparative evaluations through computer simulation.

“…It is assumed that the existing error correction techniques applied are sufficient to provide error free communication in the absence of deep fading and shadowing [22]. To further reduce the effects of segment loss due to deep fading and shadowing, time diversity is applied [23]. It can be achieved by inter-user or intra-user segment interleaving or both (Fig.…”

Abstract-UbiquitousInternet connectivity is very important in present environment. A lot of research has been done to extend Internet connectivity to vehicular ad hoc networks (VANETs). The biggest challenge to achieve this goal is the requirement of pervasive fully networked roadside infrastructure. This requirement is difficult to achieve especially during the initial deployment phase of vehicular networks and also in areas with scarce roadside infrastructure (such as along highways and in rural areas). This makes solutions that are solely dependent on roadside infrastructure impracticable to be implemented. Other solutions using cellular networks or symmetric satellite communication are either expensive or do not provide sufficient bandwidth. Further satellite communication suffers heavy losses in urban area and makes its use difficult in vehicular networks.We present a solution that complements the existing ones without requiring a fully networked roadside infrastructure. The solution uses satellite receive-only terminals and very few (widely spaced) roadside units to provide pervasive Internet connectivity. The solution is cost effective, incremental and practical. It can support TCP connection even when the uplink is interrupted for long durations of time. We present several different design options with varying degrees of error handling capabilities and different overheads and delays, which can be used according to the given environment.

y, has been retracted at the request of the author, because of a data entry error, which is fundamental to the study findings. As background, this was performance bound study based on the statistical output of a database of measures. The process involved the postprocessing of several variables and numerical data from different electronic sources aiming to extrapolate a statistical behaviour. In proceeding to design a follow-up study to this work, Daniele Tarchi went back to the original source file to abstract new data. In doing this he identified a 'cut-and paste' error in which the source data from different set have been incorrectly assigned to specific statistical processing procedures. This led to a critical error that then got carried forward and a fundamental misclassification of the findings in the final study group. This error fundamentally affects the results, which now do not fully support the conclusions.
