Recent advances in the fields of wireless technology and multimedia systems have exhibited a strong potential and tendency on improving human life by enabling smart services in ubiquitous computing environments. This paper investigates a mobile multimedia system through combining various technologies, such as wireless sensor networks, embedded multimedia system and node mobility. In particular, we will employ some powerful sensor node with both mobility and multimedia functionalities, which can be controlled by contextual information collected by other systems to enable interactive multimedia services. The new architecture is called mobile multimedia sensor network (MMSN) in this paper. A routing scheme named mobile multimedia geographic routing (MGR) is specially designed to minimize energy consumption and satisfy constraints on the average end-to-end delay of specific applications in MMSNs. Simulations verify the MGR's performance to satisfy QoS requirement while saving energy for MMSNs.
