  7. Abstract:
  8. Nowadays, deployment of peer-to-peer video streaming systems over wireless mesh networks has attained increasing popularity among a large number of users around the world. In this thesis, we present an efficient peer-to-peer live video streaming architecture over multi-hop wireless mesh networks. In our proposed architecture, we take the physical topology of the network into account and based on a distributed locality-aware neighbor selection algorithm in the overlay construction phase, we generate an efficient mesh-based overlay on top of wireless mesh networks. In locality-aware neighbor selection algorithm, instead of choosing randomly, peers find their best neighbors based on their distance. It means that the overlay neighbors are either the direct physical neighbors or located at a short distance. A prominent feature of our work is to simulate wireless mesh networks based on IEEE 802.11s standard, which makes our simulation more realistic. Our preliminary simulation result shows that peers by using a locality-aware neighbor selection algorithm instead of random neighbor selection algorithm have an approximately lower video distortion, which gives them a chance to experience a better video quality. Also, our proposed locality-aware neighbor selection algorithm reduces startup and end-to-end delays in the network
