Enhancing lifetime of sensor nodes should be considered as the key design objective in Wireless Sensor Networks (WSN). A sensor node can only be equipped with a limited energy supply and it loses its energy during data communication. In some application scenarios, replenishment of energy resources might be impossible since the sensor nodes are distributed in remote environment. Hence, the nodes lose...
Because of the limited battery power of wireless sensor network node, energy conservation is a key issue. This paper improves LEACH algorithm. Through taking into account the energy state and one-hop neighbor nodes of nodes, the improvement algorithm optimizes cluster head selection, and effectively reduces the possibility that the low energy or poor location nodes are elected the cluster heads, further...
