摘要：The availability of smart sensors equipped CMOS cameras made it possible to capture and transmit multimedia data ubiquitously. The real-time performance is essential in many applications including surveillance and healthcare monitoring in multimedia sensor networks (MSNs). One of the real-time performance indicators is to transmit the packets within their deadline. Furthermore, in information-rich, battery-powered, and resource-constrained MSNs, it is a challenging problem to extend network lifetime decreasing communication cost. In previous researches, periodic
message exchange for neighbor information maintenance leads to reducing network lifetime. This paper presents a power-aware data transmission for real-time communication in MSNs. The proposed scheme not only provides real-time performance, but also conserves energy consumption through efficient transmission and without periodic message exchange. The simulation results show the effectiveness of the proposed scheme in achieving the desired deadline success ratio and prolonging the network lifetime.
