Design issues of wireless sensor networks in ubiquitous learning

Wireless sensor networks have become an evolving technology that has a wide range of potential applications in ubiquitous computing. In ubiquitous learning environment, education is happening all around the learner but the learner may not even be conscious of the learning process. Wireless sensor networks play an important role in collecting learner's contextual information in ubiquitous learning. Firstly, we described communication architecture of wireless sensor networks in ubiquitous learning. Then, we analyzed critical design issues of wireless sensor networks that are specific to ubiquitous learning, especially on heterogeneity, localization, and synchronization. Finally, we pointed out conclusions and open research issues with regard to wireless sensor networks in ubiquitous learning.
