Low-power routing protocol of data aggregation -based for wireless sensor networks

In order to result the problem of low-power routing for wireless sensor networks, a data aggregation routing protocol with minimum transmission cost spanning tree was proposed, Data from sensor nodes was transmitted to the root node to sink node within the same sensor area. Data aggregation and transmission to the in-network sink along the shortest path is in accordance with principles of least energy consumption and energy equilibrium. Simulation results show that this protocol produced a transmitted data volume decreased by 50%-80% and a low propagation time delay.
