In today’s information society, users are overwhelmed by the information with which they are confronted on a daily basis. For subscribers of wireless data services, however, this may present a problem. Wireless handheld devices, such as cellular telephones are connected via wireless networks that suffer from low bandwidth and have a greater tendency for network errors. In addition, wireless connections can be lost or degraded by mobility. This paper presents the MobiAgent approach to accessing and using mobile agents from wireless handheld devices. In this approach, users download wireless applications to their devices that help them access and use remote mobile agents using a delegation model. This approach enhances the functionality of services by being able to operate without constant user input, and therefore it helps wireless devices to overcome wireless network limitations such as low bandwidth and disconnection.
