Opportunistic routing benefits from the broadcast nature of wireless communication and outperforms the packet losses occurring in a wireless environment, especially in the case of multicast. In this work, we present and evaluate the performance of an innovative video-aware multicast opportunistic routing algorithm in 802.11 two-hop mesh networks. We enhance a state-of-the-art opportunistic routing...
In this demo paper, we demonstrate and evaluate a novel Opportunistic Routing (OR) protocol for video multicast, namely Video-aware Multicast Opportunistic Routing (ViMOR), over 802.11 two-hop mesh networks. OR exploits the broadcast nature of the wireless medium and offers spatial diversity among the receivers. ViMOR extends MORE, a state of the art OR algorithm, by orchestrating packet transmissions...
In this paper, we propose and characterize the performance of a novel video-aware Opportunistic Routing (OR) algorithm for multicast, using a one-hop and two-hop forwarding scheme in 802.11 mesh networks. We believe that the OR approach exploits the inherent broadcast nature of the wireless medium and adapts very well in the lossy wireless environment. Inferring from the above, we extend a state of...
In this paper, we present an implementation design of a TDMA protocol for the canonical diamond-topology network containing a source, two relays and a destination (single unicast session). Getting inspired by the established Lyapunov-methodology, we propose an online strategy for the relay selection/scheduling problem. In contrast to existing works, we implement this strategy inside the proposed TDMA...
