Abstract

Advances in mobile telecommunications and device miniaturization call for the provision of standard Internet services to mobile clients. In addition, mobility suggests new classes of services that consider the client location and adapt to the limited capabilities of portable access devices. Service provisioning requires not only ubiquitous device connectivity but also novel infrastructures to support location tracking, automatic resource discovery in the device locality, service management during device disconnection and roaming, and service tailoring to heterogeneous device characteristics. The Mobile Agent properties of mobility, dynamicity, asynchronicity, and autonomy make the MA programming paradigm peculiarly suitable for developing novel middleware for mobility-enabled services. This article presents a middleware in which MAs act as mobile proxies for portable devices over the fixed network and dynamically adapt service provisioning to fit the specific characteristics of their companion devices.
