Cross-layer and one-hop neighbour-assisted video sharing solution in mobile ad hoc networks

Fast resources discovery and high Quality of Service (QoS) guarantee are the key determinants for efficient Mobile P2P (MP2P) video sharing. In this paper, we propose a Cross-Layer and One-Hop Neighbour-Assisted Video Sharing (CNVS) solution in Mobile Ad Hoc Networks (MANETs). By making use of cross-layer approaches to bridge the overlay and the MAC layer and with the help of dissemination assisted by one-hop neighbours, CNVS intelligently builds the resource-centric self-organization node cluster group. In order to meet the QoS requirement, by making use of video resources access cost model, each peer can disconnect a less efficient connection with the original supplier and choose a peer that provides a low access cost as the new supplier. Simulation results also show how CNVS achieves lower average end-to-end delay, less average number of hops for video data delivery, lower routing overhead and packet loss rate, and higher network throughput than another state-of-the-art solution.

Topology-based data dissemination approaches for large scale data centric networking architecture

Massive information flows are generated from interactive processing and visualizations. To efficiently support information transmission over the Internet, information centric architecture has been recently proposed. In this paper, we consider an information centric architecture, called the data centric networking architecture to provide communication services to big data, where a service identifier is used to name the data objects. We propose different approaches for the dissemination of data objects in a large-scale data centric network. In particular, we propose various approaches to link the data dissemination approach with the topology of the Internet. Further, we evaluate the proposed approaches with respect to data delivery efficiency, round-trip time improvement, and deployment cost. Based on the results obtained from this study, it can be shown that by disseminating data objects to small ISPs, the data delivery efficiency can be significantly improved within an acceptable deployment cost.
