As wireless connectivity is integrated into many handheld devices, streaming multimedia content among mobile ad-hoc peers is becoming a popular application. In this paper, we first introduce a mathematical model for calculating the probability of successfully streaming a multimedia object between two mobile ad-hoc peers. Unlike previous techniques that assume a constant wireless bandwidth or fixed node location, our work supports the 802.11 Auto-Rate Fallback scheme along with two popular mobility models: the random waypoint and the random walk mobility model. When delivery of the whole video content is of crucial importance, we introduce a novel streaming strategy to improve the probability of successfully streaming a video sequence based on our proposed mathematical model. This strategy takes advantage of the Scalable Video Coding scheme to adaptively select the number of enhancement layers to be streamed to the receiver. Simulation results show that our strategy can improve the probability to stream a media object by a maximum of 60% while keeping the video quality relatively high.
