Wireless sensor network consist of small sized low powered wireless nodes has spreading over a geographical area which can collaborate each other for control application. Each application consists of a control center which aggregates data from all the sensor nodes within the network. Usually data aggregation is done to compress data and save energy which introduces a possibility of time efficient method to gather data. Delay occurs often during data aggregation due to the wireless interference. The existing graph based model facilitated the improvement of efficiency, but could not reflect the superimposed effect in wireless interference and it neglected the interference of nodes beyond a certain range.
