    [[abstract]]This study proposes a method of innetwork aggregate query processing to reduce the number of messages incurred in a wireless sensor network. When aggregate queries are issued to the resourceconstrained wireless sensor network, it is important to efficiently perform these queries. Given a set of multiple aggregate queries, the proposed approach shares intermediate results among
