Routing in Bluetooth Personal Area Networks

Abstract: It is proposed that a new role: Router Node is introduced to the Bluetooth Personal Area Network profile to enable multiple hops between piconets. A proposed structure that allows transparent piconet connection is illustrated. The resulting increase in data throughput is particularly important for scalable PAN communications where multiple hops between piconets are needed. A software system has been built as a “proof-of-concept ” of the Router Node construction. A prototype Bluetooth router program has been developed in the C program language. This will enable rapid realisation of a working Router Node in hardware and software. 1
