By analyzing the many ways to monitor the reservoir water, we put forward a real-time monitoring of water resources in a more effective solution. In this solution, the Mobile Peer-to-Peer Technology (MP2P) is proved to be an effective means to administer a large number of mobile devices, whose are used to monitor the water resources in the reservoir. Because it could break the area limit of Information Island, and realize the interaction among all kinds of information in the mobile devices. This Technology builds up a universal solution for the mobile resource acquisition, query, synchronization, caching, prefetching, creating and maintenance information interactive routing, which reduces the maintenance cost of resource index table for the mobile devices, and improves the communication efficiency of the Wireless network. The simulation experiments show that the reservoir management platform constructed by MP2P technology has better efficiency than the ones by the existing technology.
