The dynamic and shared nature of wireless medium imposes an adverse barrier to supporting QoS for video streaming applications in wireless networks. In this paper, we investigate a case study of video streaming in a wireless mesh network to obtain important observations on the factors which impact video quality in multihop wireless mesh networks. Based on our analysis of the case study, we propose...
Multi-radio nodes in wireless mesh networks introduce extra complexity in utilizing channel resources. Depending on the configuration of the radios, bad mappings between radio to wireless frequencies may result in sub-optimal network topologies. Static channel assignments in wireless mesh networks have been studied in theory and through simulation but very little work has been done through experiments...
Research in wireless mesh networks have been growing in recent years. Many testbeds have been created to study networking protocols in wireless mesh networks. In this work, we describe QuRiNet, an outdoor wide-area wireless mesh network deployed in a natural reserve. We describe various research efforts that have been leveraging the QuRiNet testbed. Several interesting measurement data are reported...
Despite the increasing number of wireless mesh network deployments and research, there is a lack of understanding on how robust these networks are in practice. In this paper, we perform a systematic experimental study to investigate the impacts of different factors on the unreliability of a mesh network and the sources causing such unreliability. We use packet loss rate as a metric for defining reliability...
802.11-based multi-hop wireless mesh networks have become increasingly prevalent over the last few years. Recently, a lot of focus has been on deploying monitoring frameworks for enterprise and municipal multi-hop wireless networks. A lot of work has also been done on developing measurement-based schemes for resource management and fault management in these networks. The above goals require an efficient...
The increased deployment of wireless mesh networks (WMNs) should be complemented by a robust resource management scheme that can provide performance guarantees to mission-critical applications. Several admission control schemes have been presented for wireless LANs and wireless ad-hoc networks. However, wireless mesh networks, with static wireless back-bone and multi-hop communication, pose new design...
