Design of the Node System of Wireless Sensor Network and Its Application in Digital Agriculture

The performance and quality of services in wireless sensor networks WSNs depend on coverage and connectivity. Node placement is a fundamental issue closely related to the coverage and connectivity in sensor networks. Node placement influences the target ...

When cluster heads transmit their data to the sink via multi-hop mode, the cluster heads closer to the sink are burdened with heavy relay traffic and tend to die early. In this paper, taking both sink mobility and node deployment into account, we ...

This paper proposes a novel design of self-reconfigurable environment data monitoring system based on wireless sensor network (WSN). The system consists of three parts: sensor nodes, sink node and data monitoring center. The design supports a reliable ...
