The invention provides a resource organization system and a resource query method applicable to a wireless mobile grid. The resource organization system is mainly divided into three levels including a local node internal resource information layer, a virtual fleet (VF) internal resource information layer and a whole network resource information layer between virtual fleets. When resource query is carried out, a local primary resource information high-speed cache is queried first, then a secondary resource information high-speed cache is selected and queried, and finally a local main-control command node sends inquiry requests to main-control command nodes of other VFs according to broadcast. According to the invention, the characteristics of a wireless communication system between wireless mobile grid nodes and the characteristics of resource utilization are fully utilized, the resource organization form is of a three-layer structure, and efficient resource organization and resource property query are achieved through a two-stage high-speed cache mechanism. Compared with the prior art, the invention greatly reduces the number of messages required by resource combination and query, and improves the efficiency of resource query and the anti-damage performance of resource organization and query.
