Sinossi

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Typically, there are three types of nodes in WSN: normal sensor nodes, aggregators, and a querier. The aggregators collect data from a subset of the network, aggregate the data using a suitable aggregation function and then transmit the aggregated result to an upper aggregator or to the querier who generates the query. The querier is entrusted with the task of processing the received sensor data and derives meaningful information reflecting the events in the target field.
