Agent Based Adaptive Management of Non-Homogeneous Connectivity Resources

In this paper, a middleware architecture that enables transparent inter-operability between two different wireless networks is presented. In particular, access to the communication channel is maintained by adaptively switching between GPRS (General Packet Radio Service) and Bluetooth interfaces, both established automatically with the assistance of an RFID tag. The access channels are continuously monitored, allowing the device to switch to the Bluetooth interface, whenever this lower-cost alternative is available. A preliminary field trial has been set up, which has demonstrated the effectiveness of the approach in supporting seamless handover procedures within a heterogeneous network as envisioned for future wireless communications systems.
