Sensor networks have severe energy constraints

redundant low-rate data

and many-to-one flows.The traditional end-to-end routing algorithms are usually central and are not adapted for sensor networks.A distributed data-centric clustering hierarchical algorithm is proposed

which uses the energy-core concept to perform aggregation of data in the network and to reduce the amount of information that must be transmitted to the sink.Simulations show that

compared with the traditional end-to-end algorithm

this algorithm can significantly reduce energy dissipation.Compared with the data-centric algorithm without clustering

the data-centric clustering hierarchical algorithm offers better performance gains in complexity and scalability

while still being energy efficient.
