With the continuous progress of rural construction, the problem of rural drinking water pollution is increasingly prominent. In view of water pollution, a design of rural drinking water monitoring system based on wireless sensor networks is proposed that nodes take STM32 as the core chip and WLK01L39 as well as its peripheral circuits are used as wireless communication modules and Beidou S1216 is...
Recent significant research on wireless sensor networks (WSNs) has led to the widespread adoption of software-defined WSNs (SDWSNs), which can be reconfigured even after deployment. In this paper, we propose an energy-efficient routing algorithm for SDWSNs. In this algorithm, to make the network to be functional, control nodes are selected to assign different tasks dynamically. The selection of control...
One of the most important aspects of a wireless health monitoring system is the security of data. In this paper, security attacks against the complete transmission chain of a medical health monitoring system are enumerated and classified based on their threat to three security principles: confidentiality, integrity and availability. The communication chain is divided in a standard way into three tiers...
Smart home must use the ubiquitous computing environments and also the care systems. Accordingly the home which is smart must contain an internal network, an intelligent control and a home automation. The internal network is the priory basis; it can be wire, cable and wireless. It enables communication of sensors and actuators with each other providing services to humans. We described you how we had...
