LARP: a novel routing protocol for the Bluetooth scatternet

In this paper we design an efficient location aware routing protocol (LARP) for the Bluetooth scartternet. Taking advantages of the location information of all nodes, LARP reconstructs the routing path dynamically and minimizes the number of hops between the source and the destination of the scatternet. Besides, the paper also presents a hybrid routing protocol (HLARP), which minimizes the routing path for the scatternet, taking location information of some nodes. Experimental results show that both of our protocols are efficient enough to construct the shortest routing paths over a multi-hop scatternet and bandwidth and power consumption are least as compared to other routing protocols that we have considered.
