On-Demand Ad Hoc Routing with Modified Reverse Path Forwarding for Bluetooth
Lennart Isaksson, Markus Fiedler · 2004
Abstract — In an ad hoc network connection establishment is done to secure a path for routing packets from source to destination. This path is then maintained to secure further transmissions. In the case of Wireless Personal Area Networks (WPAN) which are more flexible, this is not usable. Some constraints in Bluetooth demand a more flexible on-demand ad hoc network compared to other types of ad hoc network protocols. Initially we found that creating a scatternet is not practically possible using Bluetooth version 1.1 as the slave/slave bridge is not implemented into the hardware. In this paper, we present a modified version of the Reverse Path Forwarding (RPF) algorithm to make it better suited for Bluetooth routing. The proposed Modified Reverse Path Forwarding (MRPF) algorithm allows for shorter message transfer times at the cost of additional overhead in the packets. I.
