Abstract: One-hop routing is used in LEACH to establish data transfer path between first level cluster-heads and the base station, which consumes much energy. In order to save energy for wireless sensor networks (WSN), an energy-saving clustering routing algorithm(DD-LEACH) based on LEACH is proposed. DD-LEACH establishes data transfer path between all cluster-heads and the base station based on plane and multi-hop routing algorithms. In comparison with LEACH, DD-LEACH performs better in terms of energy dissipation and lifetime of networks, and eliminates the restriction of the scale of the cluster-head’s communication range.
