摘要：In the application based wireless sensor networks (WSN) situation, energy and bandwidth of the sensors are valued resources and essential to consume proficiently. Data aggregation at the base station(BS) by individual nodes causes flooding of the data which consequences in maximum power utilization. To diminish this problem a new data aggregation technique has been proposed in this paper which has improved the performance of the low energy adaptive clustering hierarchy (LEACH) and stable election protocol (SEP) by using the intercluster based data aggregation also called hybrid data aggregation method, where grouping of nodes has been done on the basis of the available clustering techniques and grouping of cluster heads(CHs) is also done to utilize the features to inter cluster data aggregation. The proposed algorithm helps to reduce the energy consumption problem, aggregates and transmit the data in efficient manner. In addition, the additive and divisible data aggregation function has been used by the proposed technique at relay node and BS to minimize the power consumption and also controls flooding at BS. LempelZivWelch ( LZW) based data aggregation is also applied on the relay node to enhance the results further.
