Influence of roaming on real-time traffic in wireless networks

Resumo

This paper briefly presents an ongoing work on the roaming techniques used in wireless LANs and their impact on real-time services. Both 802.11 and Bluetooth are considered but only 802.11 offers a standardized support of mobility, which can be implemented in different ways. In the future, we want to design and implement a software layer above the existing Medium Access Control, which would allow real-time traffic to be guaranteed over standard wireless network adapters. This study will help in identifying and evaluating the implications of roaming and its impact on the quality of real time services.
