In this paper, we propose a method to deliver video for multiple wireless mobile users with different quality requirements. In the proposed method, we assume several proxies and wireless access points in the network. There are overlay links between these nodes, and certain amounts of bandwidths are reserved in advance. Each proxy is capable of executing multiple transcoding services and forwarding services. The original video sent from the server is transcoded into various quality by these services, and delivered to user nodes with the required quality along the service delivery paths. In this paper, we propose an algorithm to construct the service delivery paths which minimize the weighted sum of computation power for transcoding and the bandwidth consumed on physical links on the overlay network. The proposed method can treat user mobility where each user node moves to a range of another access point. Also, users of the proposed system can change quality requirements anytime. Through experiments with simulations, we show the usefulness of our method.
