Abstract
As advances of CMOS technology, low cost cameras and microphones have accelerated the development of Wireless Multimedia Sensor Networks (WMSNs). The data size of multimedia information is much larger than that of sensor networks. It is required to use efficient protocols on WMSNs to reduce power consumption for multimedia data transmission. The overhearing method is used to transfer multimedia data to reduce transmission overhead to transmit next packets during the unused time interval. The proposed method has been verified its performance by simulations and experiments. The results shows that the transmission rate of the proposed method 50% higher than that of End-to-End protocol. And the transmission time is reduced up to 50%. The packet delivery ratio of the proposed method is 99.7% or higher. Also the small number of nodes makes higher efficiency for overhearing and the longer waiting time to send next packet is required when the number of nodes is increased. ?
