Cluster-based routes help data transmission in ad hoc networks.Mobile users are organized into a cluster for requiring common multimedia service.However, node mobility does not guarantee multimedia transmission.This study presents a measure of cluster-based route's stability based on a prediction of connection probability at a specific time in future.The selected route is sufficiently stable to enable clustered mobile users to receive time-consuming multimedia streaming in future.Inter-cluster connectivity maintenance schemes, including forward and backward connectivity methods to provide non-stop transmission, maintain inter-cluster links.Finally, analytical and evaluation results indicate that the proposed route chosen based on the connection probability scheme is effective and stable for transmitting multimedia streaming in ad hoc networks.
