Recluster-LEACH: A recluster control algorithm based on density for wireless sensor network

Leach protocol is single-hop without considering the location information and the remaining energy. Besides, the energy balance of network can be influenced by some unreasonable random cluster head selection, which will reduce the life time of the network. Based on LEACH, this paper proposes a Recluster-LEACH protocol based on node density, which considers the density of nodes inside the cluster and adopts the mechanisms like the cluster-based data fusion, the second selection of cluster head and appropriate multi-hop algorithm to optimize the protocol. The simulation shows that Recluster-LEACH can reduce the energy consumption during data transmission, enhance the energy efficiency and prolong the life time of the whole network.
