Recent trends have suggested convergence to Wireless Sensor Networks (WSNs) becoming IPv6-based. To this effect, the Internet Engineering Task Force has chartered a Working Group to develop a routing protocol specification, enabling IPv6-based multi-hop Wireless Sensor Networks. The current effort of this working group is development of a uni-cast routing protocol denoted RPL. RPL constructs a "DAG-like" logical structure with a single root, at which the majority of the traffic flows terminate, and assumes restrictions on network dynamics and traffic generality, in order to satisfy strict constraints on router state and processing. This paper investigates the possibility for providing (effi-cient) network-wide broadcast mechanisms in WSNs, using the logical structure already provided by RPL. The aim hereof is to not impose any additional state requirements on WSN routers already running RPL. This paper presents two such broadcast mechanisms for RPL routed WSNs, and evaluates their performances. As part of this evaluation, the paper compares with MPR Flooding-an established efficient flooding optimization, widely used in MANETs.
