Abstract: Wireless sensor network consist of spatially distributed autonomous sensor nodes to monitor physical or environmental conditions (i.e. temperature, sound, atmospheric pressure etc.) for various applications. The major designing issue with WSN is resources utilization. Subsequently, work will be carried out on clustering, routing and securing node’s information for data transmission. The proposed work will be focus on minimizing power utilization during the data transmission in wireless sensor network. A data aggregation with different methods will be investigated for reducing power consumption.
Keywords: Multi Level Network Data Aggregation, clustering methods, energy efficiency, wireless sensor network.
