Abstract
According to the characters of the WSNs and its application, a new data transmission scheme, i. e., dynamic data transmission, is proposed. In this scheme, sensor nodes can predict the change of an object in the light of its history data, then decide the rate of transmitting data by the prediction. Based on the scheme and introducing the energy-aware routing method, two improved algorithms are developed from directed diffusion algorithm: directed diffusion based on dynamic data transmission and directed diffusion based on dynamic data transmission and energy-aware routing. The simulation results show that the algorithms proposed are significantly superior to previous scheme in various aspects like load balancing and lifetime elongation.
