Wireless sensor networks (WSNs) have started receiving enormous research incentives for its omnipresence in numerous applications. The Energy constraint of sensor networks has always been focus of researchers. Data aggregation is an effective technique to save energy and to enhance the lifetime for the sensor networks. Among various approaches, Hierarchical cluster-based data aggregation protocols are widely used due to high reliability and flexibility. But there is problem of unbalanced energy dissipation in cluster based sensor network. This paper addresses the problem of unbalanced energy dissipation in cluster based and heterogeneous sensor network in which Cluster heads (CHs) transmit data to the Base Station (BS) via multi-hop communication, proposes an energy efficient clustering algorithm for data aggregation (EECAD) in heterogeneous and for the characteristics of reactive WSNs. Besides, the algorithm adopts some measures to increase stability period of network and to save energy. The simulation results shows that EECAD exhibit better performance than LEACH and WB-TEEN in terms of energy consumption, network lifetime and balance energy dissipation.
