Mobile learning with Bluetooth-based e-learning system

This paper introduces a Bluetooth-based e-learning system, which enables mobile learning from anywhere using a variety of devices, including cell phones, PDAs, and laptops. Different from current e-learning systems, which require the access to the Internet or other pre-established networks, the Bluetooth-based e-learning system can establish a wireless network on the spot in an ad hoc fashion. To accommodate with the characteristic of portable devices, the system is designed for low power consumption and low learning cost. With the help of the system, an instructor can receive instant feedback from the students and check students´ performance at any time. Students, on the other hand, can actively participate in the class and answer instructor´s questions in an easier way. The system architecture, security issues, and key techniques on establishing the communication between cell phones and computers using Bluetooth on Java 2 platform are explained in detail in the paper
