For instance, aggregation can be used to estimate: the size of the network to dimension of Distributed Hash Table (DHT) structures, or to set a quorum in dynamic settings; the average system load to guide local loadbalancing decisions; the total network disk space in a P2P sharing system. In the particular case of Wireless Sensor Networks (WSN), due to energy constraints, data collection is often only practicable if aggregation is performed.&lt;/p&gt;
