In wireless sensor networks, directly sending large amount of data to the sink node may cause several problems. So, the data collection is a basic task in wireless sensor network. Certain application needs approximate data collection. In this paper, the authors focus on to collect a data approximately and efficiently with limited energy. So, they propose a technique called ADC (Approximate Data Collection). It divides a sensor network into cluster and determines data association on each cluster head. It performs global approximate data collection on the sink node according to model parameters uploaded by cluster heads.
