Location Aware Information Agent over WAP

Information agents on mobile computing environment should adaptively provide information based on the changing location of mobile users. The agent has to obtain user’s location dynamically, and respond him the information or service depending upon his geographical position. We propose a novel framework for location-aware information agent that operates on the Wireless Application Protocol (WAP) environment. There is a locating module that can obtain user’s location by GSM cellular network. A topology-based data model is devised to represent geographical information. Search algorithm can find location-dependent results from the topology graph. Search results are organized as dynamic documents, which are Wireless Markup Language (WML) cards and decks. Finally our framework is implemented with Ericsson WAP simulation environment.
