Abstract	Wireless Mesh Networks (WMN) have been widely deployed for last-mile network connectivity due to their flexibility, ease of use and low-cost deployment. When used in conjunction with peer-to-peer data transfer solutions, many innovative applications and services such as distributed storage, resource sharing and live video delivery can be deployed without any centralized administration. However, in order to achieve good quality of service in wireless environments, it is important that the associated peer-to-peer overlay is not only aware of the availability, but also of the location, of its peers and services. Focusing on the quality of video delivery, this paper first presents a wireless location-aware Chord-based overlay mechanism for WMN (WILCO) based on a novel geographical multi-level ID mapping and an improved finger table. Then, a novel segment seeking algorithm is proposed to make use of the location-awareness of the associated peer-to-peer overlay to locate and retrieve requested video segments from the nearest peers in order to improve video quality. Simulation results show how the proposed peer-to-peer video delivery solution for WMN outperforms existing state-of-the-art solutions in terms of video quality.
