We are going to focus on the technique for collecting data from sensor nodes that increase the lifetime of wireless sensor networks. In early day's research, every sensor nodes collect raw data from the environment and directly send it to the base station.So more energy are consumed to transfer all these raw data to the sink. In proposed scheme, many different sizes of clusters are created. Each cluster has different number of cluster members and single cluster head. Here number of raw data is collected by each cluster member and then all that cluster members perform local approximate data collection technique on raw data within their cluster. Each cluster member find local approximate data value and send these approximate values to their cluster head .Now cluster head performs global approximate data collection technique on local approximate data values and find global approximate value.Now send this global approximate value to the base station. The approximate data collection approach reduces the redundant data within the networks and makes the wireless sensor networks more energy efficient.
