Now, a new class of data intensive application emerges, with the development of computer network and distributed systems. The system that deals with the application mentioned above is defined as Data Stream Management System (DSMS) by the authorities in the database research field. The research of communication mechanism between the distributed querying nodes of DSMS is a challenging and hot topic.Mobile Ad Hoc network (MANET) which is of dynamic topology structure and composed of unrestricted mobile nodes is concerned increasingly. It is also a very hot research topic about how to realize data reliable communication between the mobile nodes in Ad Hoc network and how to guarantee the QoS of data communication.Considering there is little research on distributed DSMS in the Ad Hoc network environment, and on the basis of current research results in their respective fields, a QoS-based multi-path Ad Hoc routing protocol and the DHT-based communication mechanism between querying nodes in distributed DSMS are brought out.Based on ARTs-DSMS data stream management system, the DHT-based data communication mechanism is analyzed, and it can provide underlying support for data communication between querying nodes and the execution of distributed querying plan; the QoS-based multi-path routing protocol can guarantee the quality of communication service in the Ad Hoc network. And the communication mechanism of distributed DSMS in the MANET environment is finally supported by the two strategies mentioned above.
