Water regime monitoring wireless sensor network

Abstract

The invention discloses a water regime monitoring wireless sensor network and a node deployment method thereof. The wireless sensor network has a double-chain type topology structure, and comprises an information management center, sink nodes, rainfall sensor nodes, water level sensor nodes and gate level sensor nodes, wherein the rainfall sensor nodes, the water level sensor nodes and the gate level sensor nodes are deployed nearby the sink nodes and exchange information with the sink nodes in a multi-hop mode. According to the node deployment method, node deployment positions are determined according to energy consumption, and the sensor nodes and the sink nodes are deployed by adopting optimized interval double-chain structures with unequal intervals, so that the energy consumption of each sensor node is balanced, the phenomenon that the sensor nodes 'die' earlier if the sensor nodes are closer to the sink nodes is avoided, the energy consumption of the nodes in the network is greatly optimized, the sensor nodes in each area in the network use up own energy at the same time as much as possible, the life period of the whole network is effectively prolonged, the reliability is improved, and the aim of reducing maintenance is fulfilled.

Description

technical field [0001] The invention discloses a water regime monitoring wireless sensor network and a node deployment method thereof, belonging to the fields of wireless sensor networks and electronic measurement and control. Background technique [0002] With the development of my country's economic construction, hydrological forecasting and water resources management are becoming more and more important in the national economy: the automatic water regime forecasting system can measure and report water regime data such as rainfall to the information center in real time, and provide services for the water conservancy department. Providing a large amount of hydrological data has played an important role in providing accurate and scientific data for flood control and disaster prevention and mitigation. At present, many water regime monitoring and forecasting in my country mostly adopt the method of ultrashort wave transmission. This method has problems such as high constructio...
