As mobile ad hoc networks (MANETs) become more present, new ways of data exchange become feasible. This paper presents the case of multidimensional querying in wireless ad hoc networks. New challenges both in comparison with querying of relational data in MANETs and respective multidimensional querying in infrastructure based wireless networks are outlined. The main objective is the optimal execution of a multidimensional query, in terms of generated traffic, access time and energy consumption overhead. In order to address these topics, we introduce a simple and collaborative query propagation and data dissemination protocol, exclusively tailored for multidimensional data. Extensive performance evaluation validates the efficiency and robustness of the proposed protocol.
