Abstract
In recent years, the noticeable move towards using mobile devices (mobile phones and PDAs) and wireless technologies have made information available in the context of "anytime, anywhere using any mobile device" experience. Delivering information to mobile devices needs some sort of communication means such as Push, Pull, or mixed (Push and Pull) technologies to deliver any chunk of information (events, ads, advisory tips, learning materials, etc.). Events are the most important pieces of information that should be delivered timely wherever the user is. Agent-based technology offers autonomous, flexible, adaptable, and reliable way of delivering events to any device, anywhere, and on time. Publish/subscribe communication model is the basic infrastructure for event-based communication. In this paper, we define the need to mobilize the event notification process in educational environment and the possible categories of event notifications that students can receive from their educational institution. This paper also proposes a framework for agent-based mobile event notification system. The proposed framework is derived from the concept of pushâ??based publish/subscribe communication model but taking advantage from software agents to serve in the mobile environment. Finally, the paper provides a detailed analysis for the proposed system.
Highlights
Mobile devices are becoming popular in use nowadays as mobile computing and supportive mobile telecommunications network infrastructure (GSM, GPRS, UMTS, EDGE, Wi-Fi, and WiMAX) have emerged and rapidly evolve
(2) Logic Agent receives event data from the Detector Agent (DA), retrieves the list of interested students from the Database Agent (DB A), and sends [event data + list of students] to the MA. (3) Manager Agent (MA) receives [event data + list of students] from the LA and deliver event notifications to the target students' Personal Agent (PA), MA receives subscriptions from the PAs and sends them to the DB A to be stored into database
Manager Agent looks for Personal Agents (PAs) whose IDs match IDs of recipient students using the Directory Facilitator (DF), sends event notification to these PAs
Summary
Mobile devices are becoming popular in use nowadays as mobile computing and supportive mobile telecommunications network infrastructure (GSM, GPRS, UMTS, EDGE, Wi-Fi, and WiMAX) have emerged and rapidly evolve. Pull communication requires users to initiate requests for information This causes network overload, but it addresses privacy concerns associated with the Push approach [12]. Push technology is a great choice for delivering important events to users in a timely fashion. Besides timely Push service, events should be delivered according to users' interests. Event-based communication is mostly based on the notion of publish/subscribe model through which publishers publish events; these events are pushed to the subscribers according to their interests Such advantages need an intelligent and reliable approach; agent-based technology is a good choice. Agent-based technology offers autonomous, flexible, adaptable, and reliable way of delivering events to any device, anywhere, and on time.
