The availability of unlicensed spectrum coupled with the increasing popularity of wireless communication has given rise to wide range of wireless technologies. The overwhelming success of mobile devices and wireless communications is stressing the need for the development of wireless mobile application services. Device mobility requires services adapting their behavior to sudden context changes and being aware of handoffs, which introduce unpredictable delays and intermittent discontinuities. Heterogeneity of wireless technologies (Wi-Fi, Bluetooth) and many versions of the same complicate the situation, since a different treatment of context-awareness and handoffs is required for each solution. This paper presents development of a new integrated architecture for communication between an intelligent tag and a hand held mobile phone using different heterogeneity architectures and a multiple purpose access point under heterogeneous platforms. This paper addresses all issues related to dynamic adaptability, heterogeneity, coexistence and context switching between the wireless technologies.

Keywords: Wireless Communication, Bluetooth, Wi-Fi, Heterogeneity, coexistence, intelligent tag.
