A Cost Effective Compressive Data Aggregation Technique for Wireless Sensor Networks

In Wireless Sensor Network (WSN) there are two main problems in employing conventional compression techniques. The compression performance depends on the organization of the routes for a larger extent. The efficiency of an in-network data compression scheme is not solely determined by the compression ratio, but also depends on the computational and communication overheads. In Compressive Data Aggregation technique, data is gathered at some intermediate node where its size is reduced by applying compression technique without losing any information of complete data. In the previous work, the authors have developed an adaptive traffic aware aggregation technique in which the aggregation technique can be changed into structured and structure-free adaptively, depending on the load status of the traffic.
