Tree Based Data Aggregation in Sensor Networks Using Polynomial Regression
Overview This paper proposes a Tree based REGression algorithm, (TREG) that addresses the problem of data compression in wireless sensor networks. By function approximation based on multivariable polynomial regression and passing only the coefficients returned by the regression function instead of aggregated data, TREG achieves the following goals; the sink can get attribute values in regions devoid of sensor nodes for attribute values that show smooth spatial gradation; and readings over any portion of the region can be obtained at one time by querying the root instead of flooding those regions, thus incurring significant energy savings. As size of the data packet transmitted from one tree node to another remains constant, the proposed scheme scales well with growing network density.
