Constructing a Cluster-Based M-Learning Architecture in Mobile Ad Hoc Networks Using MPEG-21

Nowadays, owing to the convenience of mobile devices in our surroundings such as the PDA (personal digital assistant), cell phones, and laptops, there is a tendency toward m-learning (mobile learning) in anywhere. However, m-learning has many constraints including the computing power of mobile devices, network quality of services, and suitable learning tools. Especially, how to provide an effective and convenient platform on different mobile devices is a troublesome problem. In this paper, we propose a cluster-based m-learning architecture to achieve dynamic learning groups, and exploit MPEG-21 methods to carry out the goal.
