Contrast to the two-dimensional directional sensor networks, the three-dimensional directional sensor networks increases complexity and diversity. External environment and sensor limitations impact the target monitoring and coverage. Adjustment strategies provide better auxiliary guide in the process of self-deployment, while strengthen the monitoring area coverage rate and monitoring capability of...
In three-dimensional space, the traditional algorithm of virtual force applies to continuous target tracking process is prone to problems of distraction and short time in keeping tracking of the target in the process of. This paper proposed a three-dimensional space deployment algorithm applies to continuous target tracking to solve these problems. The combine virtual force in this algorithm is generated...
Precision agriculture is a data-driven farming practice that uses intra-and inter-field information to optimize farming operations. The "brain" of precision agriculture is a decision support system (DSS) that acquires data from various sources, analyzes them, and recommends actions to farmers. Recently cloud computing has been used to improve the scalability and reliability of a DSS. Cloud-based...
OFDMA femtocells are generally accepted as a very promising solution for indoor coverage with high data rate. However, the lack of systematic schemes to effectively mitigate macro/femtocell hierarchical interference, fully utilize radio resources, provide quality-of-service (QoS) and fairness guarantee among users suffocate the performance realization of femtocells. In this paper, an Adapted Soft...
