“…However, the approaches described in [6] [7] rely on advanced MAC/PHY protocols (such as IEEE 802.11ae) and the resulting algorithms have currently not been implemented. The multicast distribution on Wireless Mesh Networks is addressed in [8] and [9] but the suggested solutions rely on proposed advanced features for the data-link layer. [10] presents a collaborative algorithm for video streaming and cross-layer optimization, but it requires that all the WMN, including the user number and the load, is under full control.…”

Improving P2P streaming in Wireless Community Networks

Wireless Community Networks (WCNs) are bottom-up broadband networks empowering people with their on-line communication means. Too often, however, services tailored for their characteristics are missing, with the consequence that they have worse performance than what they could. We present here an adaptation of an Open Source P2P live streaming platform that works efficiently, and with good application-level quality, over WCNs. WCNs links are usually symmetric, or at least asymmetry is not by design as it is in ADSL, and a WCN topology is local and normally flat (contrary to the the global Internet), so that the P2P overlay used for video distribution can be adapted to the underlaying network characteristics. We exploit this observation to derive overlay building strategies that make use of cross-layer information to reduce the impact of the P2P streaming on the WCN while maintaining good application performance. We experiment with a real application in real WCN nodes, both in the Community-Lab provided by the CONFINE EU Project and within an emulation framework based on Mininet, where we can build larger topologies and interact more efficiently with the mesh underlay, which is unfortunately not accessible in Community-Lab. The results show that, with the overlay building strategies proposed, the P2P streaming applications can reduce the load on the WCN to about one half, also equalizing the load on links. At the same time the delivery rate and delay of video chunks are practically unaffected.
