Participatory sensing has gained increasing attention in recent years as it is promising for empowering large-scale monitoring and knowledge discovery, leveraging a crowd of public smartphone workers. In a participatory sensing system, the platform recruits workers to participate in multiple sensing processes. However, sensing processes have limited budgets. A smartphone is only satisfied when it...
Specific to the heterogeneity of wireless sensor network, this paper studies the deployment method of heterogeneous WSN based on energy-balance in terms of the heterogeneous networks encompassing two types of nodes with different energy level. In detail, this paper established the network lifetime maximum model based upon energy heterogeneous nodes ratio and managed to solve the deployment proportion...
Brain-computer interface research focused on using scalp electroencephalogram(EEG) to control outer device. The key problem is to optimize the method of signal acquisition and signal procession in the BCI research field. Appropriate method is helpful to recognize the person's intent by EEG rapidly and accurately. A novel EEG acquisition method is proved in this paper. It is to acquire EEG assisted...
