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 det-erminants 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 intel-ligently builds the resource-centric self-organ-ization 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 pro-vides a low access cost as the new supplier. Simulation results also show how CNVS achi-eves lower average end-to-end delay, less ave-rage 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.
