Monitoring and controlling microclimate in a greenhouse becomes one of the research hotspots in the field of agrometeorology, where the application of Wireless Sensor Networks (WSN) recently attracts more attentions due to its features of self-adaption, resilience and cost-effectiveness. Present microclimate monitoring and control systems achieve their prediction by manipulating captured environmental...

Different from the previous duster-based structure, in this paper, we present a grid-based load-balanced routing method (GLRM) that aims to use a controlled sink to achieve load-balance in a non-uniform distributed network. Cell-header election of each cell is based on three parameters, i.e. the number of data packets that nodes need to relay, the Euclidean distance to the mid-point of cells and residual...

In this letter, we consider cooperative spectrum sensing with the presence of malicious users. The detailed detection performance and sensing efficiency are formulated to analyze the impact of the incorrect information on the sensing system. To cope with the misleading effect of the malicious users, we further propose to implement the authentication mechanism to filter out the incorrect information...
Verifying data integrity in a ubiquitous environment is challenging due to its features such as self-organised, data-centric, and dynamic topology control. In this paper, a method for protecting data integrity is present by inserting and extracting digital watermarking information into and from most significant bits (MSBs) of original data. The method has been implemented in a real ubiquitous environment,...
Target classification is an important enabling technology for the monitoring task in transportation sensing networks. In the paper the magnetic signal and seismic acceleration signal are collected, analyzed and transmitted for a mobile road target. A classification algorithm based on the sensor network is proposed, which adopts a peak and valley pattern of hybrid detection signals from different sensors...
