Energy conservation in WSN through multilevel data reduction scheme

摘要

Lifetime is one of the major Quality of Service factors for Wireless Sensor Networks (WSN). As sensor nodes are generally battery-powered devices, the network lifetime can be extended over a reasonable time span by lessening the energy consumption of nodes. Reducing the amount of data transmission can effectively minimize the energy consumption, the bandwidth requirement and network congestions. In a WSN, denser deployment of nodes results in a high spatial correlation between data generated by
