Abstract: For different application areas, there are different technical issues that researchers are currently resolving. Sensor devices use small, low-powered and limited battery. So, recent researches have underlined the efficient energy saving protocol. Clustering techniques in WSNs are very popular and effective solution for saving energy. This study shows an energy effective clustering and data management for aggregation based on W-LEACH (Weighted-Low Energy Adaptive Clustering Hierarchy). W-LEACH is a data-stream aggregation algorithm for WSNs that extends LEACH algorithm, one of popular cluster-based hierarchy protocol. This study proposed the new method to get weights of each sensor nodes in order to increase the lifetime of network. We simulate our new algorithm to evaluate the effects of newly added weighting factor and compare the network's performance in terms of lifetime.
