WSN is a wider range of network to collect the data and extract information from the physical world. The new technology is implemented in various fields of military, science, industry, commerce etc. The sensing quality produces the good results of accuracy and tolerance to hardware and external noise. In existing system two techniques are used namely sufficient set and necessary set. But, it does not reduce the transmission cost. In the proposed system, we develop suitable algorithms namely SSB, NSB and BB for intercluster query processing with boundary rounds of communications. There are three algorithms which dynamically changes of data distribution in the network and minimize the transmission cost. In the wireless sensor networks, the sufficient set of data with two-tier hierarchical and tree structure network topologies. Hence, the experimental results show that the proposed algorithms reduce the data transmission significantly. According to various conditions which give the near optimal solutions with high performance.
