Abstract

To reduce energy consumption in wireless multimedia sensor networks

a greedy algorithm about sensing direction adjustment is proposed which enhances network coverage and reduces the sensing overhead.A type of compression cost estimation method is also described to minimize the node's power on transmission and the network lifetime is optimized according to the regularity of multimedia event stream.Simulation results show that this method obtains satisfactory performance on prolonging networks lifetime.
