Abstract
Video streaming over wireless ad-hoc networks requires appropriate routing and rate allocation mechanisms that efficiently adapt to the characteristics of such environments. The special features of ad-hoc networks also motivate us to introduce proper mechanisms in video coding, error concealment and various related areas. In this paper, we propose a framework for video streaming over wireless ad-hoc networks which utilizes the cooperation among network layers to perform the mentioned activities. We discuss the key parameters to be noticed in such a framework and explore several approaches in video streaming and rate allocation and select the suitable methods for our purpose. Focusing on the retransmission of lost video frames in response to ARQ requests, we try to minimize the delay between sending the ARQ request and receiving the lost frame, by selecting a route in which a node assists us in video streaming. Simulation results show the feasibility and the efficiency of the proposed framework.
