EURASIP Journal on Wireless Communications and Networking 2011 2011 159 EURASIP Journal on . http content 2011 1 159 Wireless Communications and Networking a SpringerOpen Journal RESEARCH Open Access Mobile multimedia sensor networks architecture and routing Min Chen1 Chin-Feng Lai2 and Honggang Wang3 Abstract 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.
