Service composition is an effective approach for large-scale multimedia delivery. One of the challenge issues is how to choose services to build a multimedia delivery path from source to destination based on user's requirements. In previous works, user's requirement is represented as one fixed functional path which is composed of several functional components in a certain order. Actually, there may be several functional paths (deliver different quality level multimedia data, e.g. image pixel, frame rate) that can meet one request. And due to the diversity of devices and connections in pervasive environment, system should choose a suitable media quality delivery path in accordance with context, instead of based on one fix functional path. this paper proposes LDpath which aims at delivering multimedia data to end users with lowest delay. It chooses services to build delivery path hop-by-hop and the generated path matches one of the possible functional paths, which essentially achieves the context aware multimedia delivery. Furthermore, the amount of data transmission deeply affects delay, thus, LDpath considers data volume changing as one of the metrics of service selection. Experimental results show that LDpath is an effective approach for multimedia delivery in pervasive space.
