T2 - Proceedings of the 7th IEEE International Workshop on Practical Issues in Building Sensor Network Applications (SENSEAPP) 2012 PY - 2012 SP - 1 EP - 9 PG - 9 UR - https://m2.mtmt.hu/api/publication/2686930 ID - 2686930 AB - Contrary to laboratory environments, real-world wireless sensor network deployments face harsh conditions where motes can be lost during deployment or in operation, for several reasons. Motes mounted on animals can easily detach. Fixed motes could get displaced by environmental conditions, e.g., heavy rains. These motes could contain valuable data and/or equipment, but finding them out in the wild could be quite challenging. Similar challenges arise in the cases where the placement of nodes is not known a priori, and yet in-field interaction with them (e.g., for data downloading or debugging) is needed. We present MOTEHUNTER, a tool supporting in-field searching for motes, composed of: the Hunter, a special node with custom hardware and software and equipped with a directional antenna, and the Prey, which can be in principle any mote compliant with IEEE 802.15.4, although a special small-footprint software component can be integrated with the application to simplify the search. We illustrate the architecture of MOTEHUNTER and discuss our design choices quantitatively and qualitatively.

Several proposals have been made in the past to optimize it, yet little experimental studies have corroborated results. The aim of this work is to provide a comprehensive experimental comparison of different strategies for the construction and maintenance of the overlay topology in P2P-TV systems. To this goal, we have implemented different fully-distributed strategies in a P2P-TV application, called PeerStreamer, that we use to run extensive experimental campaigns in a completely controlled set-up which involves thousands of peers, spanning very different networking scenarios. Results show that the topological properties of the overlay have a deep impact on both user quality of experience and network load. Strategies based solely on random peer selection are greatly outperformed by smart, yet simple strategies that can be implemented with negligible overhead. Even with different and complex scenarios, the neighborhood filtering strategy we devised as most performing guarantees to deliver almost all chunks to all peers with a play-out delay as low as only 6s even with system loads close to 1.0. Results are confirmed by running experiments on PlanetLab. PeerStreamer is open-source to make results reproducible and allow further research by the community.

They are attracting an increasing attention from the research community, the developers and practitioners. In this paper we consider P2P streaming systems based on mesh overlays and focus on the matter of automatically adjusting peer transmission rate to match the demand of the system and not overloading the uplink capacity of peers. We propose Hose Rate Control (HRC), a novel scheme to control the speed at which peers offer chunks to other peers in order to cotrol peer uplink capacity utilization. This is a critical issue to deal with in heterogeneous scenarios like the one faced in the Internet, where peer upload capacity is unknown and varies widely. Presenting extensive simulation and actual experimental results, we show that HRC nicely adapts to the actual peer available upload bandwidth and system demand, so that users’ Quality of Experience is greatly enhanced.

We propose Hose Rate Control (HRC), a novel scheme to control the speed at which peers offer chunks to other peers, ultimately controlling peer uplink capacity utilization. This is of critical importance for heterogeneous scenarios like the one faced in the Internet, where peer upload capacity is unknown and varies widely. HRC nicely adapts to the actual peer available upload bandwidth and system demand, so that users’ Quality of Experience is greatly enhanced. To support our claims we present analytical proof of the stability properties of HRC first, then both simulations and actual experiments involving more than 1000 peers are presented to assess performance in real scenarios. Results show that HRC consistently outperforms the Quality of Experience achieved by non-adaptive schemes.

For the sake of simplicity, typical P2P-TV systems are designed and optimized following a pure layered approach, thus ignoring the effect of design choices on the underlying transport network. This simple approach, however, may constitute a threat for the network providers, due to the congestion that P2P-TV traffic can potentially generate. In this paper, we present and discuss the architecture of an innovative, network cooperative P2P-TV application that is being designed and developed within the STREP Project NAPA-WINE. Our application is explicitly targeted to favor cooperation between the application and the transport network layer.

The EU research project NAPA-WINE has devised an overall architecture for live video streaming that supports the needs of the users and content providers, while being respective of network-level needs, as reducing inter-AS traffic using ALTO-like services. In this document, we describe generic elements of this software architecture for P2P live streaming and derive the corresponding implications for standardizing a Peer-to-Peer streaming protocol.
