Agro-meteorological parameters monitoring plays an important role in orchard management. For a project named `Digital Orchard' funded by local provincial government of China, a wireless sensor network was designed and developed with the aim of remote real-time monitoring and collecting of soil and atmospheric data. The system utilizes a wireless technology for data communication and data transmission...
Wireless sensor networks may be utilized for various application areas such as health, military, home, and so on. In the wireless sensor networks, data transmission typically relies on multi-hop communication with high packet loss rates on wireless links so that reliable end-to-end data transmission is desirable. Recently, in order to achieve desired Communication Reliability (CR) levels of the various...
Applying WSN (wireless sensor networks) technology to the fire safety can actualize wireless requirement, network, and intelligent fire monitoring. A wireless fire detection system based on WSN was described in the thesis, which can acquire data of temperature and smoke concentration. Fire detection nodes using SOC CC2430 as the control unit to realize the communication between nodes, the software...
In this paper, the authors propose a cross-layer security scheme for virtual MIMO networks. The scheme combines cryptographic technique implemented in higher layers with data assurance analysis at the physical layer to provide better security. The scheme can, of course, be used for a traditional non-cooperative MIMO network. First, the authors show an efficient key management system that can provide...
For the sake of avoiding the data abundance and balancing the energy consumption in wireless sensor networks, a data fusion clustering hierarchy based on data fusion (CHDF) is proposed. The clustering module and multi-hop tree are designed for data transmission. The result of simulation experiment shows that the proposed CHDF can balance energy consumption and prolong the lifetime of network.
