Innovative IP Routing Architecture for Bluetooth Scatternets: Addressing Inter-Piconet Challenges

This paper presents a novel architecture for IP networking within Bluetooth scatternets, addressing the limitations of the current LAN profile (BNEP) which fails to manage inter-piconet IP networking. We introduce a cluster-based on-demand routing strategy with the Master Relay Switch Routing (MRSR) protocol to facilitate IP forwarding between piconets. Our key design uses a piconet bridging scheme, treating each scatternet as a unified IP network with host-based addressing. We implemented this system using NS2 and extended it to the IBM BlueHoc project.
